They have gone up as high as 16! When I exercise in the morning they stay low.I split my background insulin into a 7am and 7pm dose, so when I go to exercise in the afternoon after work, my background is running low. When you exercise, if there's not enough insulin in your body, your muscles can't take in energy. As a result your liver dumps sugar in to the blood to try and give you the energy you need, leading to high blood sugars.I am DAFNE trained and my doc advised me to deal with this problem by having a snack worth more than 10g carbohydrate before the gym, which you have to inject quick acting insulin for. This would keep my body topped up with insulin whilst doing teh exercise. Based on DAFNE you would have to choose a snack and insulin dose which would bring your blood sugar to around 10 when beginning the exercise.I never have time to do this though, so trying to stick to exercise first in the morning now.Holly</blockquote>
