Question:
Hello, I have read in a few places that you absolutely should not exercise when your bg is above 10mmol. Why specifically is it a no-no? None of the books said why, just don’t okay!

I’ve never been entirely clear on that myself. I know that sometimes when you exercise, your bg goes higher first, which puts you at risk of DKA/HHS, but I dunno. — dx as Type 1 in Mar 00, joyfully pumpin’ since October!

The way it was explained to me is this. Your body perceives exercise as an emergency call for resources. If your blood glucose is below 250mg/dl, your body interprets conditions to be normal and responds by utilizing the glucose in your bloodstream. Your blood sugar then falls. However, if your blood glucose is above 250mg/dl, your body interprets conditions to be abnormal and responds by telling the liver to convert stored glycogen into glucose. The result is that your blood sugar goes UP. There’s also a corresponding release of cholesterol and triglycerides. Maybe I’ve got the details screwed up, But I’m pretty sure exercising when you have high bg makes the bg go up.

If hyperglycemia is present, one may not have enough insulin circulating in the blood stream, or the current insulin present is not capable of acting very strong which is more likely to occur the first few hours after a meal in type 1 diabetics who use low amounts of a Regular insulin with larger amounts of a longer acting insulin as compared to the type 1 diabteic who uses larger amounts of a Regular insulin with smaller amounts of a longer acting insulin. I’ve always seen blood glucose respond much easier to exercise when larger amounts of Regular insulin has been used as compared to the opposite regimen. The time frame for this type of situation to occur is typically the hours right after a meal. If there is not enough insulin circulating in your bloodstream, or if the insulin present is too weak, your blood glucose cannot get into the cells to provide energy needed and glucose begins to accumulate in the bloodstream. Sometimes during exercise, the liver erroneously believes that your cells are starved for glucose and sends more into your bloodstream. Since there’s not enough insulin to effectively work with, you accumulate more and more blood glucose, leading to hyperglycemia and ketoacidosis. This condition is of particular concern for people with IDDM. Individuals with NIDDM are not at as great a risk for exercise-induced hyperglycemia. If there is adequate insulin circulating in the blood stream which can effectively be utilized, glucose uptake into the cells can be accomplished, and the body will go ahead and use what glucose is available rather than the liver kicking out more glucose which can result in even higher blood glucose and ketoacidosis.

Thanks for all your good answers. Under my circumstances (well my fiance’s actually) it’s first thing in the morning, after morning insulin (actrapid), so there would be plenty of insulin in the bloodstream, it’s just residual high blood sugar, if you know what I mean. Sound to me like exercise under these circumstances would not be bad, and could even be a good thing Unfortunately it’s too dark after work to go cycling, else we could do that.
