Diabeto Device - The new kid on the block

Diabeto - Your friend in Diabetes!

Today is an exciting day for people with diabetes as the hotly anticipated Diabeto Device is now ready for pre-order! Diabeto have launched their impressive indiegogo campaign where you can find all the info you will need to know about the product, the ideas behind it and the dedicated team that created it. It really is impressive - You should definitely check it out! 

I have to say that I have been waiting for this device to hatch and spread its wings for what seems like forever (in reality only 2 and a bit years) and I’m really excited that it has finally happened, not only because I desperately want one, but because I’ve seen how hard the team have worked to make this a fantastic product available for people with diabetes. 

The overall aim of Diabeto is to make diabetes management easier for us, to give us a tool that is empowering, to give us insights into our blood glucose levels and what affects them and to help us to have a better quality of life.

What I like about this device (and that's before I've even laid my hands on one) is that is was created by people who went out of their way to involve people with diabetes in the design and build process. All too often I use products or apps and I'm left wondering how much real patient or carer input has gone into them, but with Diabeto I know that it's a product for people, not just for a condition. This is something that's very important to me as the diabetes/tech industry continues to grow and I think many companies could learn a lot from these guys.

Team Diabeto

Diabeto comes in 2 parts - The birdy device (see pics) and an app. The bird plugs into your blood glucose meter and sends (via bluetooth) your blood glucose info over to the app on your smart phone. Readings are then stored onto a secure cloud server so you can access them. Simples! 

Here are some of the features that I really like: 
  • The device itself really appeals to me. It's fun, small and doesn't look like a medical device. Great for kids but I'm almost 29 and I would definitely use it
  • It can be used on the go
  • The app allows you to track more than just your glucose. You can track your mood, insulin, carbs and activity as well as review your blood glucose log.
  • You choose how much or little you want to track
  • The app will plot a blood glucose graph for you so you can pick up trends and patterns. This can then be sent to your health care team in pdf format - putting the patient in the drivers seat
  • The app is free and available on iOS and pebble watches. Android users (myself included) hopefully won't have too long to wait for the app
  • Readings are secure in the cloud
  • Diabeto is compatible with 25 blood glucose meters and the team are working on making it compatible with more
  • Diabeto uses open source hardware meaning that schematic, design files and a bill of materials can be downloaded and used by anyone - The Diabeto team wins some serious cool points for opening it up to the community!

Take a look at the indiegogo campaign for more details on the device and also details on how you can pre-order your very own Diabeto. You'll see that you can also get the device at a special price - The first 100 birds are only $49 (usual price $59)!!

They also have a range of cool perks should you wish to support and contribute to Diabeto including:
  • $1 - A thank you for being part of the family gets you regular updates and your name on the website's 'Thank You' page
  • $15 - Diabeto stickers and your name on the website's thank you page
  • $25 - Diabeto Rockstar t-shirt
  • $29 - Rockstar T-shirt and sticker pack  
and there are a whole load of great offers on Diabeto packs!

Medtronic MiniMed 640G and SmartGuard Technology

Yesterday I went off to Medtronic’s UK head office expecting to continue with our usual blogger and patient advocacy meetings. What I didn’t know was that I was actually going to be given an exclusive preview and test run of the new Medtronic MiniMed 640G insulin pump and CGM system with new SmartGuard technology! Now that's what I call a good day! 

As a Medtronic patient advocate I have been working alongside them, with a group of other patients and carers, to help them move into the world of social media and digital health care, and to offer an insight into what patients really want from diabetes technology. This in itself bought me the opportunity to travel to Amsterdam last year to blog about their Diabetes Junior World Cup, and here I was again, with yet another opportunity!

I should explain something else… I’m not currently a Medtronic user, but what I really like about the company is that this doesn’t matter to them. I have diabetes, I live with it day in day out and I have views about it – the products that I do or don’t use (often this is out of my control anyway) doesn’t matter to them. This, of course, doesn’t mean that I won’t be a Medtronic user in the future and with the new and exciting MiniMed 640G technology, I could be easily persuaded.

So… enough about me… the 640G is what you need to know about!

The MiniMed 640G is a sensor augmented insulin pump. Medtronic has a vision and that is to create an artificial pancreas and their 640G is the next step towards achieving that vision. Their aim is to create technology that gives people more freedom, improved safety and better health when it comes to diabetes. We know that many companies have this same aim but this product (from what I saw) really does deliver those aims.  

The 640G uses a new technology called SmartGuard. SmartGuard is designed to give people advanced protection against hypoglycaemia and hyperglycaemia. The intelligent system has been based on the wants and needs of people who already use the Paradigm Veo insulin pump, providing better blood glucose control and safety, especially when it comes to nocturnal hypos – something that I think worries us all from time to time.

The system is similar to Medtronic’s Paradigm Veo but, as I said, it’s far more advanced. The Veo has a low glucose suspend function in which the pump will turn off insulin delivery for up to 2 hours if a person's blood glucose levels reaches a pre-set low glucose threshold. However, the new SmartGuard tech will turn off insulin delivery before a person's blood glucose hits the low glucose threshold, therefore avoiding hypoglycaemia. It does this by predicting a persons blood glucose levels 30 minutes before they are going to drop (providing they are also using an Enlite CGM - Continuous Glucose Monitor). The prediction is based on how quickly the person’s levels are dropping. The pump will alarm/vibrate to alert the person that the insulin delivery will then be turned off (for a minimum of 30 minutes) and will stay off until their blood glucose starts to rise again or until they feel better and manually override the system to turn their insulin delivery back on. 

When insulin delivery is turned off to avoid a hypo this means that all insulin is turned off - basal and any bolus programmes that are running - e.g. dual wave. If the person would prefer to eat/treat before the auto-suspend starts then they can stop the suspend function and treat the impending low like they usually would. The user is very much in control of how the system works. 

A high threshold can also be set, in which the pump will alarm/vibrate if a person is going to reach their high level, therefore allowing them to manage the impending high (correction, temp basal increase etc). The pump will not automatically deliver more insulin if a person is reaching their high threshold - This is what a closed loop system (artificial pancreas) is but the technology isn't quite there yet.

One important question that was asked by fellow blogger Mike (@everydayupsdwns) was; What happens if a person’s blood glucose drops below the pre-set low glucose threshold but does not rise again within the 2 hours that the insulin delivery has be turned off for? The answer is that the pump will only turn delivery back on after 2 hours if the person has physically interacted the pump e.g. pushed a button, therefore the pump is recognising that the person is aware of the hypo. If, for example, they are unconscious and do not press any buttons, the insulin delivery will be suspended for a further 2 hours, so 4 hours in total. After those 4 hours… well I just hope that the person would be found by then.

We joked that the pump could have technology like cars do which alerts the emergency services if it is involved in an accident and its location. I actually think this is a brilliant idea. Maybe something for the future, eh :) 

We were told that the algorithm that is used in the SmartGuard technology was the same that was used in the Pilgrim Study in which 80% of hypos were avoided during exercise. The remaining 20% were due to levels that were dropping at a very fast rate which resulted in the persons blood glucose levels hitting their low threshold marker. 

This brings me to alarms and vibrations. In the situation Mike mentioned above, alarms will be set off by the pump to alert a person that they are heading towards, or have reached, their low glucose threshold, therefore hopefully alerting someone else to the unconscious person. It’s a scary reality, but something that we do need to think about as people with diabetes.

The alarms can be turned off though! If you’re sitting in a meeting or your child is in assembly, or if you just want to sleep the whole night through (and you’re other half too!) the low and high threshold alarms can be turned off to avoid that beep beep beeping. The person using the 640G can turn the alarm off themselves, but this doesn’t mean that the low or high thresholds will be turned off. It just means that if a person is heading for a hypo then the pump will deal with it without alarming. If a person turns off the hyper alarm then the pump will not be able to do anything about the levels heading up. Sounds a little scary doesn’t it… Turning off the alerts and letting a device do its thing... but as @LwSweetpea88 pointed out – It’s hard to trust new technology, but you don’t know what it will be like until you’ve tried it.

A few quick bits about the MiniMed 640G

  • It will be available in the UK, Sweden, Denmark and Australia – I believe it will be launched in early February (the 2nd)
  • It’s licensed for use by children 
  • It needs a calibration at least every 12 hours
  • The sensor life is 6 days
  • If a person decided to restart the sensor past the 6 days then it may well result in a calibration error – if the sensor has 2 calibration errors then it will stop working
  • Low level auto-suspend had a minimum suspend time of 30 minutes
  • Insulin delivery will only be turned back on when the trending arrows on the receiver are pointing up (meaning that glucose levels are rising sufficiently)
  • There are a choice of high and low alarms
  • There is an alarm if the user’s blood glucose levels do hit the low threshold (though the aim of SmartGuard is to avoid hitting this threshold)
  • The user can choose to have no threshold at all
  • The pump pairs (via radio frequency) with the contour next link USB blood glucose meter
  • The pump has a bolus wizard, the blood glucose meter does not
  • The blood glucose meter can tell the pump to deliver manual insulin doses (decided by the person using it) or pre-set doses - e.g. 2 or 4 units
  • The pumps come in cool colours (and I think look a little like iPods)
  • It’s not too big and not too small – comes with a clip and you can also buy Lenny the Lion rubber protective cases for it! 
  • The pump has a colour display screen
  • The display on the pump has colour coded icons which let the user know if they are running low – e.g. the battery will be green, amber or red depending on how much battery is left 
  • The screen is a lovely size (really important for me as my retinopathy means I’m always squinting at my tiny pump screen)  
  • Both pump and CGM are waterproof  
  • The system uses the Enlite sensor & guardian link transmitter (the transmitter has been improved - so we were told)
  • The pump has a 'back' navigation button! This may seem like a small detail but my current pump does not have this, meaning I have to scroll through all options if I miss the option that I want
  • 5 basal settings can be used, temporary basal rates can be set and the pump has options for bolus doses to be delivered in different ways (e.g. dual wave)
  • The pump does not need to be used with CGM - It can be used as a stand alone insulin pump (obviously this will leave the user without the option of the low and high thresholds, alerts and CGM trace etc)
  • CGM data can be uploaded via Medtronic's software package, CareLink, and sent to your diabetes team
  • People will be able to purchase supplies through Medtronic's e-shop

Something I haven't mentioned is price... and that's because I don't know it. I did ask the question and I was told that it wasn't a huge step away from the Veo and enlite sensors as a combination, but we will have to wait for more information on that one. 

That brings me to the end of the scribbled notes that I took during the meeting... I suppose the only question I need to ask myself based on what I saw and know is would I use it? 

My answer (if self-funding and CCGs didn't have any influence over my decision) is yes, without a doubt! I'm fed up of waking during the night with low glucose, worrying about what my levels are doing and if I'm going to need to treat a hypo during a meeting or whilst I'm on placement. I'm fed of of the growing fear that one day I might need an ambulance call out or that my driving licence might be taken away from me, that I might end up in a dangerous situation due to my diabetes. I'm also bloody fed up with my constant battle with hypos and exercise! But that's a whole other story.

I hope this blog has been useful to you... I'm aware that I have been using notes to write much of this blog but I hope what I have said is accurate. I'm sure Medtronic will be releasing more information soon, but until then please feel free to share this with anyone who might be interested!

Diabetes – My Beautiful Disaster

Diabetes – My Beautiful Disaster

There is no knowing when you hear those words spoken,
“Your body, we can’t repair, you will remain broken.”
What this would touch was a mystery to me,
They said it may disable or kill… we shall see.

The years, they slipped by and yet there was nothing,
The admissions, the warnings, they must have been bluffing.
I’m invincible you see, with a layer so strong,
You can tear it down, but I will build it up, though I know that it’s wrong.

“She won’t accept or apply or attend” they said,
“This girl, she’s too stubborn and full of neglect.”
But what clouded my thoughts were those words once spoken,
“Your body, we can’t repair, you will remain broken.”

More years, more admissions, more avoiding the concern,
Then one day it hit, it was time for my turn.
“You’ll be blind within the year” they said, as I lay on a table,
Their masked faces above me, poised with tools, I was unstable.

I drifted away, sleeping soundly as they worked,
Waking to the pain, and a weak voice that once lurked.
“You need to control this, you need to get better,”
“Don’t hold yourself back, it’s now or never.”

Alongside that voice was another much stronger,
“Don’t let them control you, you’ll be free no longer”.
Remember those words that were once spoken,
“Your body, we can’t repair, you will remain broken.”

Why try, why fight, why bring myself pain,
This life thrust upon me, I had nothing to gain.
They said it themselves, there was nothing to give
The fight it would take, would it help me to live.

The months, they passed by, I was reluctant at first,
It’s not fair, why me, why had I been cursed.
I resented my body, my thoughts and my actions,
But I needed to fight, face my fears, escape distractions.

The years they passed by, no blindness in sight,
Had I won a small battle, had I lead the fight.
The fear resides inside me, the tales spoke the truth,
I wish I’d acted sooner, before exhausting my youth.

I took a stormy journey, filled with disappointment and blows,
But on the other side of this disaster is a beauty that grows.
And so, to those words that were once spoken,
It’s my body, it’s my fight and your words… they can be broken.

The Language of Diabetes

I’ve been thinking recently about the way that I talk about diabetes and the way that others communicate with me and also about me. Language is a very powerful tool used in discussions about diabetes, and a person’s choice of words can greatly impact on a patient and the way that they manage their condition.

During a recent consultation with a diabetes Professor, he described my blood glucose levels using the words “bad behaviour”...

Red White and Blue - The Eye Of The Ninja

I wanted to blog about diabetic retinopathy and my red white and blue vision... past present and possibly future.

Part one - A non diabetes related issue diagnosed my retinopathy.

In September 2009 I suffered from terrible headaches which lasted for 2 weeks - non stop they pounded on my head day and night, making me nautious, dizzy, tearful and obviously quite distressed. You'll all be relieved to know that this part is not diabetes related! 

After the the first 2 days I went to my GP and was told to take pain killers. I had been doing this anyway, but I didn't want to go against the advice of my GP, so I continued with the pain killers. I returned days later quite desperate but was told that pain is a good thing, that I needed to know it was there to be able to assess if it was getting better. I repeated the visit again a few days later with a swollen eye (Quasi Modo style) and was given cream.

After 2 weeks I finally gave in and went to A&E. I had an MRI scan which showed that I had a lump of swollen tissue behind my right eye which was so large that it had worn a hole through my skull and was pressing on my brain. So much for the eye cream eh?! I was told that cancer was a possibility, and a biopsy would be done to diagnose. After the biopsy the headaches left, the swelling settled, I had a funky zig zag scar on my eye lid (still got it) and I was referred to a specialist eye hospital in London called Moorefields.

So where does my diabetes come into this? I was told when first admitted that I had early stages of retinopathy and I would need laser treatment. I was told that the swollen tissue could be diabetes related, but it might not be and it would be assessed. I didn't see anyone for my diabetes while I was there or after I was discharged. Naievely I thought that if people weren't worried enough to see me or talk to me about my diabetes and the first stage of retinopathy, then I didn't need to worry. Naievity is the bigggest regret that I will ever have.

Back and forth I went; seeing different specialists, having my eye poked and prodded, photos taken to be used for educational purposes. scans, blood tests etc but nothing came of it. The last corrospondance that I had was a letter that I was copied in to. It explained that the nature of the swelling was extremely agressive but it had gone as quickly as it had come. I wasn't diagnosed - no one knew what it was, and that was it. Done. Finito. Months of panic stress and worry were followed by silence. Not complete silence though, I was still reviewed every six months - eyes checked, progress was made and no more talk of retinopathy. I thought I was in the clear. I thought I was invinciable!

Little did I know that my journey was only just beginning...

I hate hypos

Recently I've been noticing, a lot more than usual, how my diabetes makes me feel. In the last few days the highs have been making a big impact and it wasn't until a few days ago that I remembered one of the biggest reasons for why I used to purposely keep my blood glucose levels high - The hypos... I hate them.

They crop up at awkward moments (in a meeting, exam, during a date, important presentation etc) but I always try to carry on as normal.

They mean I have to eat sugary snacks after exercising – this seems counter-productive to me. 

They’re never the same – some are surprisingly easy to deal with and some are just plain nasty, taking me down in every way they can.

They cover me, my clothes, my bed etc in cold sweat. Having to leave the room so I can take off my top isn't always easy/appropriate/legal(?).

They give me the giggles at a time when I shouldn’t be giggling. This is usually during one of those awkward moments mentioned above. They also make me cry in public or turn into an angry ______ (insert word).

They make my legs turn to jelly and my head turn to lead - waking up with low blood glucose levels means a day of suffering from a headache that doesn't leave, no matter what you do. This is known as a 'hypo hangover'.

They put me on edge, making me overly aware of how I feel and what's happening. I start to be very careful about what I say or do. Even moving a cup requires all my concentration at times. 

They give me 'hypo hair'. This is when you wake up from a low blood sugar with what resembles a birds nest on top of your head, usually with that lingering damp feeling (see cold sweat hypo). 

They ruin a run of good blood sugars. Obviously, good blood sugars aren't appearing on my meter at the moment, but on the occasion when I do have a good run (and I feel oh so proud about it), a hypo messes up all that hard work I've done.

Diabetes is tough

I was prepared for clinic yesterday. I knew what I wanted to say and how I wanted to say it. I had planned to have a serious talk about my diabetes control and management, an honest and open discussion that would provide insight into how I could work with my consultant to get to where I wanted, and needed, to be. I had rehearsed it over and over in my head the night before and in my head the outcomes had been good.

As I sat in the waiting room I flipped my phone over and over in my hands, looking at the new art work on the walls. For that brief moment I felt calm and composed, soaking up the vibrant colours as I felt my heart beat slow down. When I was called in by my DSN I realised I wouldn’t be seeing my consultant that day. No problem – My DSN was always kind, understanding and never judgemental. I was in good hands.

I started to talk. I admitted to letting things slip, pointed out my mistakes and gave my own suggestions for I could rectify them. I was asked how I knew things had slipped, and I realised I didn’t. We tried to get blood for a HbA1c – it didn’t happen. I sat sobbing, as always, whilst the nurse tried to reach a vein before it moved. I felt selfish as I walked back through the busy waiting room. Why should I be crying when every one of these patients is going through the same (if not more) as I am. Why should they see my tear stained face as they sit, probably feeling anxious themselves, waiting for their turn. How selfish of me.

The tears didn’t stop. “Is it the blood test or something else?” I was asked. Soon I was crying harder. I talked and talked, letting everything come out. What I wasn’t doing, what I was doing, why I was choosing to make those decisions, why I’m scared, what my future looked like, what’s stopping me from asking for help. I was asked what I wanted to do next. I didn’t want to do anything. I didn’t want to set any goals, plan for the future or create any expectations. I just wanted someone, somewhere, to be aware for when I am ready. I left my DSNs office and in the corridor were a group of consultants, amongst them was my consultant. I looked at him with my mascara stained eyes and then looked at the floor. One of the things I hate most about diabetes is that it makes me feel I’ve let him down. People will say this is a silly but it’s how I feel.

Later that night I had a text. “Everything ok? Clinic looked tough?”

Everything’s not ok but clinic isn’t tough. Clinic is a safe place, it does its job and more. It’s diabetes that’s tough.

Asking for help

I find that my biggest struggle when it comes to diabetes is asking for help. Those who know me well know that I can occasionally be incredibly stubborn (or as those people would say, a massive pain in the arse) and that admitting that I may be in over my head, or even just wandering down the wrong path, is very unlikely to happen. Then, I reach that moment when my persistent denial or refusal to accept that a situation has reached the point where I should have handled things differently, ends with me reluctantly accepting the help that has been there from the beginning. Often too late.

I was born in the 80’s and in the 90’s was plunged into a world of Brit pop, girl power and iconic independent feminists! Perhaps I take things to the extreme by being so very reluctant to accept help, perhaps it was (and always has been) a way to keep some distance between myself and my health care professionals or perhaps I just don’t want people to know that I’m not as good as I think I am, or as good as I would like to be.

It’s funny how people handle things in different ways. I could, with open arms, welcome and embrace the support and advice that is available to me. Hell, my health care professionals are the best around and I know that there would never be an instance where I would be turned down should I need them. I could suck it up, shake my hair, shout “girl power” and get right back in the game… but isn’t it scary to know that getting back in the game requires one of those big conversations. One that involves admitting that there is something wrong. It’s never as easy as clicking your fingers and hey presto – the broken pieces have been fixed.

The other option, the easy way out (or so it seems) is to walk. Walk away from the problem, from yourself and bail when things get too real.

One of the things that I do is to drop hints, rather than admitting that things are on a downward spiral. It’s a well-known fact that health care professionals, whilst training, attend detective classes… right? Just like when they’ve qualified they take a year out to practice mind reading… Obviously, dropping hints to a consultant who works god knows how many hours a day and has god knows how many patients to see, is the right way to go about addressing a problem. No? How about spending time with them, dancing around the subject of diabetes, dipping in and out, trying to pluck up the courage to speak up only to leave 45 minutes later the same as before?

Ok, so I know that’s not the way to go about things but isn’t it scary to admit something… something you wanted to deal with yourself but can’t… then have someone confirm and reiterate it? Not only that but to then have it confirmed with blood, with data from a questionnaire, with patterns on a graph, with a letter to your GP and a copy sent to your home? Knowing that the problem you once had will always be with you wherever you go... on file as a constant reminder. I think for me, the biggest blow is realising that I’m not as self-sufficiant as I once thought. After 12 years of living with diabetes I should expect to be getting something right, to be finishing at least a few days out of the week feeling well and in control... not worrying about what the next day will bring. On the other hand though, doesn’t being scared just mean that I’m human? Fear is a universal human reaction, right?

I suppose when it comes to health there are really only two choices. To own it… or to abandon it. Either way, I think that admitting you’re not heroic is when you’re the most heroic of all.

FreeStyle Libre - data download

I just wanted to post a few examples of the charts that you can download straight to your computer from the Libre. 

I'm really impressed with the variety available and I feel that this is the first time I've really understood my data. Previously I've been presented with those horrible spaghetti lines that come muddled together on one graph, with only different colours to tell the days apart. I used to sit with my consultant and let him do all the work when it came to picking out patterns - He's always rocked at that part anyway!

However the charts and info that the Libre displays has been a huge eye opener and for the first time I feel that I can make changes to my insulin without the help of my diabetes consultant! I'm like my very own diabetes Health Care Professional (without the letters behind my name)! 

Patient Power!! 

Daily patterns

Glucose pattern insights

Monthly Summary 

Daily Log


Weekly Summary

There are also options to view meal time patterns and user data. The software is really easy to use - Just download it from www.freestylelibre.com and connect your Libre to your PC/laptop via the USB cable provided with the reader. 

As I said, I'm really impressed with way that my data has been presented and the different options I have to view it. It's very empowering and I love knowing that I don't need to go through the routine of making an appointment to see my consultant, heading to my diabetes clinic, battling to download my data via the system they use and then sitting with my consultant whilst he number crunches and I go cross eyes looking at the screen.

I'm currently giving a BIG thumbs up to Abbott!

FreeStyle Libre - Flash Glucose Technology

FreeStyle Libre… The new diabetes product that has been the talk of the town, or certainly the Diabetes Online Community (DOC), for the past few weeks.

The technology itself is called flash glucose. It isn’t marketed as a CGM (Continuous Glucose Monitor) or a blood glucose machine, it’s something different… something completely new (and very interesting) to the diabetes market. The way that the Libre works is by reading glucose levels through a sensor that can be worn on the back of the upper arm for up to 14 days. The sensor itself (approximately the size of a two Euro coin) measures glucose every minute in interstitial fluid through a small (5.0mm x 0.4mm) filament that is inserted just under the skin of the arm. A touch screen reader is then used to scan (flash) over the sensor (it can scan through 4cm of clothing) which then gives the user their blood glucose result in a pain free, discreet and convenient way, as many times as you like - No finger stick calibration is needed. A historical trace is then formed over time and the also reader shows the user which direction their blood glucose is heading in – Steady, slowly going down, rapidly going down, slowly going up or rapidly going up.

The Freestyle Libre has been marketed as;

A revolutionary new glucose sensing technology for people with diabetes”

“A significantly advance the field of glucose monitoring”

“Offering a convenient and painless way to get more frequent glucose readings, which should help to improve diabetes management

But we all know that marketing means nothing to a consumer these days if it’s not backed up with genuine user reviews and opinions, especially when it comes to a medical device that we, people who have diabetes and don’t just talk about it, need to use on a daily basis… need to trust every second that we are using it… So that’s why Abbott (the pharmaceutical company behind the FreeStyle Libre) invited me and a group of other people with Type 1 diabetes to London last week, to be amongst the first in the world to be able to try the Libre before it hit the shelves! 

What does the Libre look like?

Ok, so I was given a starter kit to take home with me – 2 sensors and a reader. The shiny yellow packaging with an orange butterfly is familiar to me and told me that it was an Abbott product (I have a few Abbot products at home), but packaging is just a barrier to me getting to what I want and really doesn’t mean much to me at all. After ripping my way through that barrier, I found inside the sensor box the sensor itself (in sterile packaging), an inserter (also in sterile packaging) and an instruction manual. Inside the reader box is the reader, a battery charger and USB cable, along with user guides, starter manuals etc.

The sensor itself, when on my arm is about the size of a £2 coin and about the thickness of 2x £2 coins. It has a super sticky adhesive to make sure it doesn’t ping off and that’s all you can see. The needle comes straight out with the inserter and gets throw in the sharps bin (if you geta Libre you will need one of those MASSIVE sharps bins).

The reader is relatively small (see pic below), easy to hold or pop in a pocket or handbag and is very lightweight. It feels like it would bounce if it hit the floor (this is something I won’t be testing out!), the screen, if you push gently on it, is quite flexible and doesn’t seem like it would break if you accidently left it in your back pocket and sat on it. Saying that though, it does feel a bit… cheap. Though at the price it rocks in at I wouldn’t expect to be holding something that would give the iphone 6 a run for its money!

The reader only has 1 button, it has a large colour screen that’s also touch screen, a decent sized text for those who, like me, refuse to wear their glasses, and it well lit (more about the reader later). A nice surprise that I wasn’t expecting when I opened it is that it can also test blood glucose in the way that most of us are used to, with a finger prick, and is also a blood ketone meter!

The Libre doesn’t come with a case or any accessories to ‘funk’ it up but from what I’ve seen, people in the DOC are pretty good at doing that themselves and I’m sure it won’t be long before some of the more creative people have pimped their Libre's.

Is it comfortable? Does it have to be worn on the skin?

It’s very comfortable! I can’t feel a thing when I’m wearing it, sleeping on the side that it’s on or when I’m moving my arm (not that I madly flap my arms around anyway!) The only time I’ve felt it is when I pulled my handbag strap up my arm and caught it but that didn’t hurt, I was just aware that I did it.

When I asked the Abbott staff if it could be worn elsewhere I was told no, only on the back of the arm for now. This has been the 1st time for me that I’ve had anything on my arm (I've never injected there or inserted a pump cannula) so I wasn’t overjoyed at the thought but as I said, I can’t feel it and often forget it’s there.

How much does it cost?

The starter kit containing 2 sensors (lasting 14 days each) and a reader costs £133.29 +VAT

The reader on its own costs £48.29 (with a 2 year warranty) +VAT

A sensor on its own costs £48.29 +VAT

Note – People with diabetes don’t pay the VAT on medical products. Please get in touch with Abbott for more info about this.

Did it hurt putting the sensor on?

Not at all! I didn’t feel a thing and I was really surprised by this! I’m used to feeling a pinch and a slight sting when I insert my insulin pump cannula but the Libre was pain free – everyone else who tried one that day said exactly the same. One of the staff from Abbott who was there on the day watched me as I inserted the sensor and said that I scrunched my face up just before putting it on. I must have been anticipating a sharp scratch, but I was very pleasantly surprised.

When can I get one?

We were told that the Libre will be available to buy online from the end of September/early October. You might want to contact Abbott yourselves nearer the time to see if they have a specific launch date.

What does the reader do?

As I said before, the reader is used to manually scan over the user’s sensor in order to see an instant blood glucose reading - all information is stored for 90 days. The reader also has many options to view the data depending on what you want to know.

The main screen, after scanning, shows the time, battery left, amount of time before the sensor ends, the glucose reading, the trace history on a graph and an arrow to show which direction your blood glucose is heading. Other options include; a logbook, daily graph (with options to look back over other days), average glucose in 4 time blocks (going back 7, 14, 30 and 90 days), daily patterns, time in target (also above and below target) and your personal target range, low glucose events (anything below 3.9mmol/l) and sensor usage showing the amount of times you have scanned.

All of this information can then be downloaded to your computer via a USB which is included. I’m yet to download but I’ll blog about it when I do.

How easy is it to set up?

It was really easy! I’m not one to read instructions but for this I wanted to make sure that I didn’t cock it up so I did have a look at the enclosed manual. Step by step the process of inserting the sensor is explained with text and pictures – If I can do it, anyone can!! When it came to setting up the reader you just need to follow the instructions on the screen – date, time, target blood glucose etc. and you’re all set! The reader takes 60 minutes before you can scan for the first time (and I imagine this is the same when starting with a new sensor) but has a lovely countdown clock letting you know when it will be ready for use. As far as makig changes goes I’ve been able to re-set the time on my reader and adjust my glucose target with no problems. There is only 1 button on the reader, which makes navigation through the menu’s quick and easy, the rest is done via the touch screen.

Who can use it?

The Libre will be available to people in the UK, France, Germany, Italy, Netherlands, Sweden and Spain. Currently Abbott are only able to sell the Libre to people over the age of 18, though they did stress that they are committed to actively pursuing its use in patients under 18. Watch this space!!

Will I still need to prick my fingers?

Personally I have been using my old blood glucose meter but not as often as I was. For me, I need to use my old blood glucose meter to calculate my insulin:carb doses and correction doses, my meter also bluetooths that information to my insulin pump, therefore eliminating the need to go rummaging around in my bra to press buttons on my pump when I’ve stashed it in there.

Abbott did stress that if someone is making decisions about taking insulin based on a reading from the libre they should check their blood sugars on a separate meter as there is a 5 minute time delay from the number you see on the screen to what your glucose level is. There is an option for Health Care Professionals to work with patients who use the Libre which will allow them to set the Libre up to give insulin suggestions, however I haven’t been able to try this feature yet as I’m not working with my HCP with my use of the Libre. Abbott did say that they are trying to reach as many HCPs with the Libre as possible so they can help patients if they have any questions or want to discuss their diabetes management alongside using the Libre.

Something I’ve also been doing when using the Libre and testing my glucose on my meter is comparing the results to see what difference there is in the given readings. So far I haven’t noticed differences that are jumping out at me and suggesting that the Libre is way out when it comes to accurately measuring my blood glucose. As I mentioned earlier, we need to be able to trust technology, which is why I’m comparing it to other meter readings on occasion.

How accurate is it?

This is a tricky one... Upon meeting with Abbott we were told that they were very confident that the Libre was more accurate than the current technology out there, The first day went very well and after making comparisons with my trusted accuchek blood glucose meter I was impressed at how close the readings were - only 0.2mmol/l out at the most!

As the days went by this gap slowly widened and I did begin to question the accuracy (taking into account the 5 minute time delay) and if I would base any insulin calculations on the information given by the Libre.

About 30 minutes ago though I flashed and had a reading of 3.7mmol/l (hypo). I didn't feel low so I checked on my meter as Abbott had recommended we do to make sure we weren't
making decisions solely based on one reading and saw that my meter read at 4.0mmol/l. Which was correct?? I grabbed a third meter which showed 4.5mmol/l! I flashed 20 minutes later and the Libre says my glucose is 3.3mmol/l... I don't feel hypo at all and 2 meters say I'm not, but do I risk not treating in case the Libre is correct? What if I wanted to get into my car? Do I now need to wait 40 minutes based on the Libre but not the machine that I have used and trusted every day for the last year?

I think you would need to make up your own minds on this one... 

What if a sensor doesn’t work?

We were told that if any problems occur with sensors or readers then to get in touch with Abbott who will replace or refund. The staff that I spoke with said that they are confident that the readings won’t ‘drift’ over the 14 days but if someone does find a problem then to contact their customer service team.

My Pros and cons:


  • Convenience - It's so quick and easy to pull the reader out of my pocket or bag, flash it over my arm and look at the reading that shows I just 1 secon
  • It's a pain free way to check blood glucose
  • It has boosted my confidence - I feel much more able to get on with my day knowing that I can easily check my glucose as and when suits me
  • I can 'flash' as many times as I like
  • I can see how certain foods affect my blood glucose
  • I can see which direction my glucose is heading in which enables me to act accordingly
  • I can see trends that I've never seen before - in the last few days I've seen that my overnight glucose is between 9-15
  • It's comfortable to wear and insert
  • It enables me to download 90 days worth of data which I can analyse myself and send to my diabetes team if necessary
  • It's incredibly cheap in comparison to some technology (some readers cost hundreds!)
  • It's easy to set up - I often worry about this as I'd hate to make a mistake and not be able to use it
  • It's aesthetically pleasing - colour screen, charts, large text etc.
  • It's not bulky - one of my worries about having something 'stuck' on me is that it will be obvious through clothes. My pump is easily stored in my bra and I'm pleased that the Libre sensor is discreet enough to cover with clothes if I wanted to
  • The battery life seems to be good, though this will depend on how many times you 'flash'
  • It doesn't need a finger prick calibration
  • It is enabling me to self-manage better and is making me feel much more involved in my diabetes care now that I am more aware of what my blood glucose is doing - It's strange how 'in the dark' I felt when restricted to finger pricking a certain amount of times a day


  • If you don’t scan for more than 8 hours you can’t see a trace history – on the rare occasion I do sleep for more than 8 hours
  • Low glucose events – recorded when bg gets to 3.9mmol/l or below but I often feel hypo when my glucose goes below 4.5 – this eliminates some of the personal element
  • I could become reliant on the technology
  • It could cause me to become obsessive about testing my glucose levels
  • It doesn’t completely eliminate the need for finger prick testing
  • It offers the option to test blood glucose and blood ketones but doesn’t include a lancet, test strips or ketone strips
  • If my HCPs didn’t want to help me with the Libre/didn’t buy into the idea then I couldn’t use all of the options available to calculate insulin doses (to allow access the insulin calculator need HCP access code)
  • When making notes I can only put rapid acting insulin in whole numbers – Not accurate for pump users as we can use 0.1 units etc. on pump and some insulin pen users can use 0.5 units
  • Not as many options for looking at trends as my current meter - accuchek combo which offers daily, weekly, charts, scatter graphs, pie charts, standard deviation etc.
  • Can only put on back of arm – I much prefer using my stomach
  • And the biggie... I can’t afford it. Yes it’s an amazing price compared to current diabetes technology that can be self-funded but as a student who isn’t able to work full time, I can’t spare £96 a month.

So... would I buy this product (if I wasn't a poor student?) At this point in time, the jury's out on that. This is only my 3rd day of using the sensor and apart from the mixed messages with my hypo(?) I have been very impressed. I plan to make a few video blogs throughout the next few weeks so please keep an eye out for more updates. I hope this blog has been helpful for you! If you can afford it then perhaps it might be worth trying it out for yourself as the initial start-up cost is much lower than CGM technology... everyone is different and this may be the product you've been looking for!
