Hi -
I'm 46yo, fairly fit, T1 for 20 years. Currently injecting Fiasp + Levemir. Blood sugar moderately well controlled, though I can see peaks of up to 20 occasionally (every few weeks), and will hit 11-13 after meals, though that comes down fairly quickly. I'm on a Libre, so can see the peaks. I try and do an hour a day of exercise in the evenings on work days - mostly cycling, though also one run/week, and weekends I'll do a longer walk or bike ride.
My Diabetes team are very keen on me doing more carb counting than I do at the moment. I'm less sure than they are that it's a great idea. Here's my reasons :
I've informally carb counted for years - I've got an idea of how much food corresponds to how much insulin, and will happily change doses to fit what I eat. (though my normal meals are fairly regular, so portion size and hence insulin dose don't change much through the week)
The biggest thing which affects the amount of insulin I need is exercise. On a working day, I can take 20u of Fiasp + 12u levemir with breakfast, do a 2km walk, and be stable through the day sitting at a desk, with a couple of snacks. On a weekend day if going for a walk in the hills (eg 10mi), or on a cycling day, I can take 8u of Fiasp, same Levemir and then have to eat through the day after the carbs from breakfast have gone.
On the second day of little exercise (eg it's raining a lot) sugars start to go a lot higher too - that 20u + 12u might go up, or additional injections, and the snacks have to cut down a lot, despite being hungry.
This tells me that accurate carb counting can be completely irrelevant - there isn't a sensible starting point for accurate insulin/carb calculations, so my informal guesswork is actually good enough.
What I'd like to do is be able to adjust my insulin a bit more dynamically, but obviously that's hard with the basal on a long acting insulin - once that's taken, I can't reduce it, so I've got to eat to correct instead. But my diabetes team insist accurate carb counting is the important thing before we can look at other options.
Any thoughts?
(obviously this is just a brief summary, there's a lot more to say, so I'm not after detailed analysis, but an idea if I'm wildly inaccurate or if others have experienced similar issues would be useful)
cheers,
clive
