7.8 with no breakfast or early morning brew at 8am. Struggling at the moment, straight to the gym 90mins relatively tough workout. 750ml water during and decaf coffee 1 brown sugar after. Home 20 mins later BS of 8.5. No idea what I’m doing wrong.
Hi
@chrispem, welcome to the forum.
You don't say how long you've been diagnosed, but reassured that you are probably doing nothing wrong at all! Diabetes is frustrating and random at the best of times, but so far as I can see, its also highly personalised, because everyone's response to sugar and carbs in food is different, at different times, depending on what else is going on. And add hard exercise into the mix, and you have a whole new variation to factor in.
What took me a while to discover was that some types of exercise can actually raise my blood sugar quite significantly in the moment, for example a 30 minute swim could take my BG from around 6 to 8 or 9, even without any food being taken. This alarmed me a bit to start with, but its simply the body getting ahead of itself and pumping sugar out of its stores to enable it to do cardio exercises. Even when you stop exercising, the BG will go to repair the tissues and recover, so will get used up relatively quickly, rather than floating around for a while in the blood which is what causes the damage. I also discovered that a gentle walk after lunch, would take my BG down quicker, because the rate I was burning blood sugar was faster than the amount going into the bloodstream. So now I no longer worry about the raise in BG with exercise, it just happens and so long as I don't try and over compensate (like with a bag of crisps or a choc bar) its not a problem. Ultimately, the exercise is good for my system, mentally and physically, so I just carry on and ignore the temporary rise in BG.
The other thing I never do now is take any kind of neat sugar if I can possibly avoid it. There are so many other reasonably palatable sweeteners which will not add to the BG numbers, even brown sugar is neat glucose and will cause me a sharp rise. So I avoid like the plague, despite my previous breakfast of choice being porridge, brown sugar and cream!
