High sugar level after exercise

[gulabs]

Wanted to share an abnormal sugar levels that I have noticed recently. In the morning my sugar level was around 8.2, I did some breathing exercise and measured glucose levels again, I expected it to be lower than 8.2 but surprisingly it was 12.5. I didn't eat anything in between. I have also noticed similar abnormal readings after walk/exercise. Anyone has similar experience

When were you diagnosed as my readings stayed the same for some months before they dropped off. They started to settle when I began losing weight and diet

Welcome to the forums @gulabs

What type of diabetes do you have and are you on any medication for it?

I find my readings are often affected by the dawn phenomena (my liver releases glucose first thing to help me get active for the day) and I have to inject insulin even if I don't eat breakfast. (I'm T1 so make none of my own).

As regards exercise, heavy exercise at the gym (eg weights) generally pushes my levels up, whereas a walk pushes them down.

As allready suggested read up on the dawn phenomenon. I have it and find that doing exercises raises my BS in the morning. For me it does not matter if I do low intensity exercises or high intensity. When I do the same exercise after the dawn phenomenon peak (say after 13:00) it does not raise my BS.
When you say you see abnormal readings after walking/exercising. What time is that? Morning or afternoon?

Hi. I find a walk after a carby meal flattens out the sugar spike and prevents it from getting as high as it otherwise would (presumably because my body is making use of the sugar). Going to the gym is a bit different. Initially I get a blood sugar spike (which is I guess what you saw). After a while though - and precisely when varies (it can take anywhere between 20m to an hour) - my blood sugar will then dip. I think what is happening here is that my body initially tries to provide higher blood sugar levels to fuel the exercise, but after a while uses up these supplies, which is when we see the levels dip.

Due to my current level of (un)fitness, any exercise causes a stress response, so I get a big sugar spike. My sugars then typically stay higher for up to 24hrs. My hope is this will diminish as my fitness improves.
