The "I can..." of insulin pumps - Diabetes Week 2014

The theme of this year's Diabetes Week is 'I can...'. Here's a guest post I was invited to write for the Diabetes UK blog.

When I was thinking about this year's theme of 'I can' I was reminded of a conversation I had with someone last week about insulin pumps. It was something that they were being encouraged to consider, but like pretty much everyone else (myself included) their initial reaction was uncertainty. Uncertainty over being connected to something 24 hours a day. Uncertainty about relying on a fragile piece of technology to keep them alive. Uncertainty about how it would make them feel and how others might view them. Uncertainty over whether it would actually improve anything at all. In short, they didn't really think it was for them.

I know those feelings well. I had them all, and many more besides. I was 'pump averse' for many years. My clinic suggested that it might help with my recurrent hypoglycaemia, but could never really articulate how that might happen. All I could see was a big bunch of (what I thought were) downsides.

In the end, for me, it was reading the experiences of pump users online that convinced me to give it a go. The day to day nitty gritty of how it helped them. Now I'm not saying that insulin pumps are for everyone. Some people wouldn't want to touch one with a barge pole, others do just fine on Multiple Daily Injections and are completely happy as they are. But if it is something you are considering, here are a few 'I can's that an insulin pump has given me to add to your thinking:

If I want to go to bed at 5.0mmol/L, I can.
Ahhhhh basal! I have been through quite a few basal insulins in my 25 years of pancreas-impersonation. In the old days we were always advised to have a snack before bed. Why? Well because in all likelihood your basal-du-jour was going to be a bit over-enthusiastic in the early hours and could well plunge you into an overnight hypo. It was many years before I discovered 'basal testing' (systematically adjusting your basal insulin by fasting tests so that it just holds you steady) but try as I might, even with fancy schmancy analogues I could only ever get my basal 'near enough' on MDI. A bit too much here, not quite enough there... make up the differences with meal doses and guesswork. With a pump, the flexibility of multiple basal patterns which can be tweaked and changed with almost infinite precision mean that I can adjust things so that I am actually starting from a level playing field. To my mind, basal is the bedrock of my BG levels. If my basal is out, even by just a little bit, my meal doses and corrections just do not play fair. So I no longer have to worry about stocking up on carbs before bed, because my basal insulin should hold me level and when I need less insulin overnight I get less. Where I need more just before breakfast, I get more.

If I want to give a really accurate dose, I can.
My doses on MDI were often a bit 'ballpark' to be honest. I have always counted carbs and altered my doses based on what I am eating, but I usually rounded up or rounded down to make things easy. Plus I would use insulin:carbohydrate ratios that meant I didn't have to get a calculator out all the time. The Accu-chek Expert was a great tool on MDI for tweaking doses, but I was still using a 'whole unit' pen so there was a degree of rounding even then. Now I can bolus in decimal places. And those tiny tweaks of insulin here or there do seem to make a difference. True enough my carb estimates are still often done by eye, but at least one part of the puzzle is now being calculated and delivered precisely.

If I want to stop here for lunch, I can.
This was the biggest surprise for me. Rediscovering spontaneity. I began pumping with an fairly entrenched anxiety about being hooked up to something 24/7. I know almost no one who has not had that when considering an insulin pump. Many people say that within a few weeks (days for some people) they become completely at one with their new robot pancreas and never give it a second thought. I can't say that it was quite so quick for me, but certainly in less than six months I had stopped noticing being attached at all and my emerging 'unthought' behaviours (like automatically hooking it to a t-shirt when getting changed) meant I never really gave Artoo another thought. If you are newly on an insulin pump and it still feels a bit of a nuisance or 'in the way' hang in there. Where was I? Oh yes... Spontaneity. So I was well prepared to dislike being attached, but I really hadn't expected that attachment would turn out to be such a bonus. Out on a wander on holiday... get a bit distracted and it takes rather longer than anticipated... Oh this pub looks nice, shall we stop for lunch? What would have always previously been "No we can't, I didn't bring my pens with me" has simply become "Yes!". Wherever we are now I always have my 'kit' with me, and while I used to like the idea of being able to leave all this stuff on a table and just walk around 'like a normal person', personally I have come to realise that I feel much more 'normal' if I can eat whatever I fancy whenever I want to, without having to remember to bring a case full of gubbins with me everywhere.

If I want to have 20 boluses/corrections/snacks in a day, I can.
Well strictly speaking I always could have, of course. But in reality I never did. There is something so easy and effortless about push-button dosing that I am far more likely to add in a fraction of a unit here or there during a day when I recognise that I probably wouldn't have bothered to get a pen out, airshot, dial up and inject. This has increased freedom around snacks too. Where I previously found them just to be too much of a hassle on MDI, almost always resulting is a BG wobble in one direction or other (depending on whether I had bothered to bolus or not) I've had much more success with the effortless mini-doses a pump offers. It's easier, so I bother to do it.

If I want to run a marathon (or just vacuum the stairs), I can.
Again, this was something I more or less tamed with MDI, but the additional options available on a pump, like the ability to set a 'temporary basal rate' for several hours, have added considerable 'polish' to many of those day-to-day conundrums of physical activity. I am far less likely to see my BG levels dip below my target range when exercising these days and I'm buying far less Lucozade!


Just a few things of the top of my head. I'm sure most people on pumps could write their own list. Of course diabetes is still annoying and frustrating quite a lot of the time. A pump is not a magic bullet and it still involves a fair bit of faffing about. But for me having a pump has made a tighter set of BG levels more possible, with less effort and far, far fewer nasty lows.

If you are struggling with wrestling your diabetes into some sort of submission and have been offered a pump as a possible way forward I'd suggest giving it a go.

If I can do it... You can.

Diabetes Week - Artificial Pancreas Project

It's Diabetes Week in the UK this week and after my rather forlorn post about the apparent disappearance of C8 medisensors non-invasive CGM last week I was pleased to read this little update on the Artificial Pancreas Project (APP) from Diabetes UK today.

It's still reasonably early days, and to my mind we are still quite a way off a 'real' management solution, but step by step people are cautiously being allowed to hand over the reins overnight to an automated system in their own home rather than under strict lab conditions with technicians standing by the bedside clutching Lucozade and NovoPens.

For those of you who have *no* idea what I am going on about, the Artificial Pancreas Project is seeking to 'close the loop' between two clever bits of diabetes kit. A Continuous Glucose Monitor (CGM) that can measure glucose levels and an insulin pump that can provide varying doses of insulin. In fact most people who happen to see my pump tend to assume that we are there already, and assume that a pump will just somehow 'know' how much insulin is needed and provide it automatically. Sadly it's not quite that easy, and while an insulin pump is a brilliant therapy option it does still require a fair amount of effort, guesswork and to be honest more than a little luck in balancing all of the hundreds of variables involved in day-to-day BG tomfoolery.

Part of the problem with the APP of course is that the technologies involved are improving, but still rather less than perfect. Continuous Glucose Monitors make an estimate of blood glucose levels based on glucose concentration in interstitial fluid (the stuff sloshing around between cells in tissue). This tends to lag a bit behind actual BG values, and those lucky enough to have access to CGM will know that what you are really getting is 'trend' information rather than the accuracy* of blood-based fingersticks. CGM manuals/marketing are usually pretty clear that any doses/corrections made should be done after confirming results with a fingerstick test. But the closed loop system needs to use this very same stream of trend information in order to make dosing decisions.

Currently the human trials of the APP are showing relatively promising results for looking after things overnight. To know that you had a smart system carefully tweaking your levels while you slumbered would be fantastic, but of course a full Artificial Pancreas would have to go much further and tackle the thorny issue of mealtimes. Personally I think we are a looooong way off that. For one thing current 'rapid' analogue insulins are hopelessly inadequate for the task. They take far too long to get going (1 hour for corrections to start taking effect anyone?) and act over far too long a time period to give a bunch of electronics, however smart, the ability to take over entirely.

What I would hope for instead is a commercially viable 'smart pump' which combines much of the effort and user knowledge/experience that currently goes into effective pump use, but with automated AP trickery to take the edges off the errors and irritations of daily pancreas impersonation. A system whereby you would bolus for meals, set TBRs for activity and generally do the basics, but the pump would be constantly monitoring how things were going and have the ability to tweak things and make corrections to keep things on a more even keel.

Now that really would be something.




* It should be noted, of course, that fingerstick BG tests in themselves are not particularly accurate and only really serve as a general guide as to what is going on.

Scapegoats, Lobbyists and the Perfect Storm

Apologies for the recent flurry of posts. It's been one of those weeks! Last night I watched the first of the BBC's 3-part documentary 'The Men Who Made Us Fat' (available for the next three weeks on BBC iPlayer).

I had been eagerly awaiting the programme since reading an article in the Guardian that someone tweeted a link to (thanks Louise!).

I was not disappointed.

It makes me wonder if this is the year that people will look back on in the future as a real turning point in the public's understanding of the obesity crisis. This programme, the article and several others in the media in recent weeks are finally focussing on factors other than saturated fat when talking about problems with the modern western diet.

The programme focusses on the decisions made in the US in the 1970s which profoundly affect the current mainstream thinking on dietary health and what we eat today. Decisions which in the end seem far more based on economics and agriculture than health. I can't pretend to be any kind of expert on these things, having only a passing interest, but it was amazing for me to listen to a programe that (for once) did not just bang on about fat in the diet when talking about the western world's weight problems. Unsurprisingly Ancel Keys influence on the subject was covered. He, famously, took against saturated fat. According to the programme, on a trip to the UK in the 1950s he began to believe that saturated fat was at the root of the major health issue of the time - heart disease (cue grainy black and white pictures of toothy children scoffing fish and chips). He then set about proving his theory.

I have heard the name Ancel Keys many times before. I have seen his work vilified and passionately defended on several diabetes forums. Sadly, in the end I don't think it matters what he actually said or wrote at all. His proposals seemed to be based on a mediterranean-style diet with plenty of fresh veg and olive oil and only moderate carb intake. What happened is that when it came to the question, "What is causing all this heart disease, fat or sugar?" the incredibly powerful industry lobbyists had their scapegoat. Saturated fat became the enemy. There was no 'saturated fat' lobby. No specific industry to protect or promote. The incredibly powerful Sugar Association in the US (powerful enough it seems, to prevent the World Health Organisation from setting a maximum limit on recommended sugar consumption), and the political might of the US agricultural industry swept everything before them. The portions got bigger... The stuff we ate got sweeter (sometimes with lovely shiny 'low fat' labels)... The snacks were more relentlessly available... and our self control was, frankly, not up to it.

I'm not (quite) cynical enough believe that the soft drinks/processed food industry chose the cheaper corn syrup/glucose-fructose syrup/HFCS as sweetener of choice knowing that it turned off leptin, the chemical in your brain that tells you when you've had enough to eat. I don't think the fast food giants and food manufacturers cared about anything other than increasing their market share and selling more and increasingly refined and processed products. Having said that, it was with horrifying inevitability that the spokesperson for the US soft drinks industry said that she did not believe her industry's products had anything to do with the crisis in the western world's waistlines (despite being the single largest source of calories in the US diet).

For the last 40 years we have been told that fat is the enemy, saturated fat in particular. Carbs are good. Fat is evil. Attention is now finally veering towards sugar. And if you consider the 'Tsunami' of glucose that hits the bloodstream when eating sugary foods to be a bad thing, then perhaps it is worth reflecting that many of the things I have been told are 'starchy' and 'slow release' have proved anything but under examination from my blood glucose meter (even with the benefit of modern 'fast acting' analogue insulins to tame them).

I'm not some kind of be-sandalled ultra low carb evangelist. To be honest I have profound reservations about the extremes of viewpoint in any kind of discussion. But in a world where people with type 2 diabetes (essentially an intolerance to carbohydrate) are continually told that they must base every single meal they eat on the very substance which most rapidly raises blood glucose and threatens to fry their eyes, feet and kidneys it was refreshing to watch a programme that raised serious questions about our addiction to carbs in general and sugar in particular. At the risk of sounding like my parents - once again it seems that 'moderation' is the blindingly obvious, crushingly simple answer.

The next edition of the programme considers ballooning portion sizes. I can't wait!

Are you 'Type 1 Aware'?

As part of Diabetes Week in the UK, D charity heavyweights Diabetes UK and JDRF have launched a brilliant video which asks the question 'Are you Type 1 Aware'? It focusses mainly on those who develop type 1 diabetes in childhood and clearly explains the very obvious symptoms which are all too easy to ignore and/or be dismissed by busy GPs as parent paranoia. Having been diagnosed in early adult hood I know myself that it was several months of feeling really rotten before I finally decided I should go and get myself checked out by a GP.

Alarmingly some of the parents in the video share how close to death their children were before they were finally properly diagnosed.

Please share this video with your family, friends, parents, teachers and anyone you know who works with children or young people. You could save a life.

Family support for T2s

Way back when this blog was just beginning Jane wrote about the lack of support offered to families and partners of adult diabetics. Quite rightly there seems to be support available for parents of children with diabetes, but for those diagnosed in adulthood there seems little in place in terms of help and education unless partners, spouses or carers are able to push their way into appointments with the patient.

It seems that bastion of high street chemistry Boots is trying to change that, at least for the families of people living with type 2 diabetes. Research undertaken by Boots and supported by, among others, Dr Katharine Barnard, Health Psychologist and Senior Research Fellow at the University of Southampton suggests that families could be pivotal in supporting and motivating someone with type 2 diabetes, who at the very least should have access to good information about how their diabetes is treated and what sort of checks they should be receiving.

With 80% of the NHS’s 9.8 billion annual UK diabetes bill being spent on treating complications*, mobilising the wealth of latent support represented by these willing family members could prove a powerful weapon in better management of Type 2 Diabetes and in improving lives. Eight in 10 (81%) family members say they’d use extra support if it were available which is why Boots UK has launched a new Diabetes Information Service that not only provides support for people living with the condition, but also valuable advice and guidance for their families to help them start having better conversations.

* largely preventable

I get a bit nervous when these kinds of organisations start wanting to dish out advice to people with type 2 diabetes. Partly because I see so many people on internet forums who have a terrible time coping with their type 2 based on some of the questionable advice they get from their healthcare professionals! There was also a fairly disastrous campaign by Lloyds recently which provoked quite a lot of disquiet among diabetics by failing (as is often the case) to properly differentiate between types of diabetes.

I really hope this initiative goes well. A family which understands the crucial role carbohydrates play in the management of type 2 diabetes is less likely to say, "Oh surely that won't matter?". A family that understands how difficult type 2 can be to control is less likely to think, "It's only diabetes, just take a tablet and carry on as before". A family which all eats the same diet together make it easier for the person with diabetes to stay on the wagon. A family that understands the potential consequences of poor control will be better at motivating their loved through the dark days.

I haven't had a chance to see the Diabetes Information Pack, and have only briefly looked at the the information on the Boots WebMD website. Thankfully I didn't see much evidence of the usual "people with type 2 diabetes must eat lots of starchy carbs" nonsense, but I can't guarantee it isn't there lurking in the shadows so be wary. Encouragingly they also suggested that self-testing is important in the management of everyone with diabetes (well they do sell the equipment after all). If only we could get GPs around the country to feel the same way.

If you have a family member with type 2 diabetes how able do you feel to offer support? Comments please!

Disclosure: I was sent 'press release' information about Boots new Diabetes Information Service, but was not paid to write this post (I wish!)

Making Connections - Diabetes Week guest post on DUK Blog

I was delighted to be asked to write a guest post for the Diabetes UK blog as part of Diabetes Week 2012. Diabetes UK’s theme this year is ‘Make a Connection’ – here are two takes on that:

1. Making connections is the worst thing about diabetes

Diabetes is, for want of a better word, *incredibly* annoying.

I can’t really comment on the vagaries of type 2 – though I have read enough comments from people trying to wrestle their type 2 control into submission to realise that it is at least as contrary and inconsistent as type 1. Let’s be honest, there are days when type 1 diabetes can seem to be deliberately out to get you. Some days it just seems to get it into its head to ‘go off on one’ and there is simply no reasoning with it. Confusion and contradiction abound.

It doesn’t help that on other days, weeks even, it can seem to be entirely reliable and meekly obedient. Behaving the way the doctors say it should. Ratios and factors all present and correct.

It doesn’t even help that of all the chronic conditions, diabetes is one of the most livable-with. If I was going to have to have a chronic condition, diabetes would be pretty high up the list of ones I’d choose.

I can remember comments I got from friends and colleagues in the years soon after diagnosis, “Oooh, I could NEVER inject myself! I don’t know how you can...” – as if that were the hard part! The injections, the testing, the clinic appointments… These are all minor inconveniences. Even carb counting is easy enough and becomes second nature after a short while.

The really tricky thing about living with diabetes is the number of variables involved in the day-to-day running of things – and all the inter-related connections between them. Whenever my levels go all over the place there always seem to be 101 possible causes, lots of head scratching and false-starts before things settle again. Only to go out of kilter a few weeks later.

The body is amazingly good at controlling blood glucose levels. Really, spectacularly good. Most ordinary people wandering about have NO idea of the complex goings-on inside them. The ebb and flow of hormones keeping blood glucose levels within a tiny range no matter what they eat or what they do. It’s only when you suddenly have to start playing at being your own pancreas that you realise how amazing the body is.

The difficulty for us, of course, is that the body is SO good, that it’s a pretty tough act to follow. If the body usually kept blood glucose levels somewhere between 2-20mmol/L we’d all be laughing . But there’s a lot to juggle when you are trying to ‘do it yourself’ and live up to the body’s high standards. The grams of carb eaten... The dose of insulin for those carbs... The likely speed of absorption of the carbs... Likewise the likely absorption profile of the insulin. Not to mention the background insulin required to cover output from the liver, or for that matter, the liver suddenly deciding that this hour, or day, or week needs far more (or less) glucose than normal. Activity? Illness? Stress? Ambient temperature? It’s a wonder we ever get a decent level.

It’s worth remembering that when you are having a bad week. Playing at being your own pancreas is a big ask. We won’t always have all the information. What worked brilliantly last month won’t necessarily work as well this week (because this week is, of course, slightly different in a million seemingly inconsequential ways).

There is never going to be a ‘right’, only ever a ‘right for now’. The best we can do is keep on testing, writing things down, looking for patterns and chasing the moving goalposts.

2. Making connections is the best thing about diabetes

Diabetes is, for want of a better word, *incredibly* annoying.

It can also feel like quite a lonely place to be. For perhaps 18 years I lived my diabetic life supported by friends and family, but without really knowing anyone else with diabetes. I’d met only a handful of people with type 1 in my life, and stumbled across a few more with type 2, but none of their experiences seemed to relate to a diabetes that was anything like mine.

After a while the suggestions and comments from my clinic team were all very well, but they didn’t seem to fit with what I was experiencing – or worse still, were things I’d already tried and knew didn’t work for me. I was having a few too many highs, a few too many lows (but then doesn’t everyone?). My HbA1c was OK-ish. I didn’t seem to be frying my eyes too rapidly. I supposed I convinced myself that this was as good as could be expected.

But then a few years back I had an unusually nasty hypo (long story, short trip to A&E). Suddenly my understanding changed. Good enough was no longer good enough. We began to write this blog as a family, to begin to think about diabetes in a slightly more ‘front of mind’ way.

I began testing far more frequently, writing everything down, looking for patterns. I began to look around for other people to compare notes with. Found and read some amazing blogs written by people with diabetes from all over the world. Joined forums where I could ask questions, read experiences, or just generally rant and moan about the silliness of it all.

There is nothing like making connections with other people who instantly ‘get it’.

There is no question you can ask that will be considered too silly or too obvious.

There is nothing like reading a post written by someone on the other side of the world who is able to express exactly how you feel about a shared experience.

There is nothing like sharing one of your experiences, only to give someone else a ‘lightbulb moment’ over something they have been struggling with for years.

There is nothing like sitting around a table at a social event and having everyone pull out a BG meter before eating.

Making connections gives you access to the latest thinking and approaches from clinics all around the country (or all over the world).

Making connections makes you feel less alone.

Making connections makes diabetes easier to live with.

There are hundreds of people all over the world (and just around the corner) who know what it’s like to face what you are facing every day. Who can encourage you and support you. Who can make your diabetes easier to manage.

Go and make some connections of your own.
