I was speaking with someone who is thinking about starting to Loop the other day. I explained my own experiences – how simple the set-up had been (even after I’d delayed it for six months because I thought I wouldn’t be able to do it), how it is completely changed the way I think about diabetes, how much less time I have to dedicate to dealing with the daily frustrations of diabetes, how the highs and lows have been evened out and how glucose rollercoasters are a thing of the past.

‘So, you never have highs and lows? Ever?’ he asked me.

‘No; that’s not completely true,’ I said. I am frequently guilty of being evangelical about diabetes technology, and wanted to be sure that I wasn’t overselling DIYAPS. ‘After all, I still have diabetes!’

I have my range set to 4mmol/l – 8.0mml/l. It’s the mythical range that was presented to me as the ultimate goal the day I was diagnosed. It’s quite a tight range – I know that – and I probably could afford to ease up on that upper range. My target is 5.0mmol/l (it used to be 5.5mmol/l – another mythical number).

The reality is that for the very vast majority of the time, I am within that range, and hovering around that target number. If I was to check my Dex as soon as I woke up each morning, it would be boringly somewhere between about 4.8mmol/l and 5.3mmol/l.

But I still do spent time outside of the target range. The thing about Loop is that in most cases, I can explain the reasons when that happens.

I had a hypo the other night. A pretty terrible one, actually. I can’t remember the last time my Dex read LOW, but that was what I was staring at when I checked the app after my phone started screaming at me. I double checked with a finger prick and sure enough I was low. Really low. I treated (over treated) and was fine a short time later, albeit with a rebound leading to numbers I’ve not seen in a very long time.

How did that happen? Well, let’s start with the double bolus I gave myself. For some reason, I decided that the chicken soup with noodles I was eating for dinner needed not one, but two boluses. That was mistake number one. Mistake number two was not eating as much as I thought I was going to because I had a teleconference starting, so I left about half of my dinner in the bowl. Mistake number three was not realising mistake number one. And mistake number four was not doing anything to address mistake number two.

Following? Diabetes is fun!

The low resulted in an ‘eat-the-kitchen’ hypo that saw me eat six jelly beans, wait fifteen minutes and then recheck my glucose levels. Just kidding. I drank half a litre of juice, ate three bowls of breakfast cereal, chomped on a tube of fruit pastilles and then started attacking a homemade fruit bun my mum had delivered earlier in the day.

Because I was dying and all the carbs in the kitchen were the only way to prevent that happening.

The high that followed could be easily explained (see: juice, cereal, pastilles, fruit bun).

Other highs on Loop can usually also be explained quite simply. If I under bolus, I know pretty quickly, and Loop has already started doing its thing anyway to remedy that.

Stubborn highs generally mean one thing and one thing only: Renza, change your cannula. And as soon as I do, numbers come back into range fairly quickly.

Out of range numbers these days aren’t due to the unpredictability of diabetes. These days, they come down to one thing and one thing only: human error. My human error.

I trust Loop more than I trust myself. It is way smarter, completely and utterly unemotional, and an absolute workhorse, making adjustments every five minutes as required. It doesn’t get tired or busy or distracted. It understands numbers better than I ever will.

This is the cool tech I need to help me keep my diabetes moving. Of course, I still need the warm touch – the human connection – to help me make sense of my life with diabetes. But not having to think or do the diabetes numbers nearly as much gives me time and headspace I didn’t know I had. It keeps my numbers in range for the vast, vast majority of each day. And it means far fewer errors. Errors that I used to make all the time.

I am, after all, only human. Loop, on the other hand, is not.
