My readings have gone up from about 7/8 to 12+
Hi
@Tipe2too When have you been checking your readings?
For many people exercise raises bg levels that's normal and something you want it means you are using up stored glucose from the liver which causes the increase.
The hot weather can raise bg levels. As can a restless night due to the muggy weather. Then as others have mentioned the "dawn phenomenon" your liver dumps loads of sugar into your system to kick start your day add that to a hot morning and a sleepless night and its a triple whammy.
For so many of us we are left to fend for ourselves with this condition and its through trial and error we find out what works for us. Stress can play a part even something as simple as worrying about your blood sugars being raised, can raise your blood sugar.
Just a thought are you carb loading before exercise?
