How does exercise lower blood sugar levels?
Pathophysiology please. I know that during exercise glycogen is broken down for energy. THe circulating glucose in the blood then needs insulin or else hyperglycemia occurs. SO how are blood sugars lowered during exercise?
And if you have blood glucose over 250 mg/dl, why should you delay exercise? DOesn’t exercise lower blood sugar levels?
Blood sugars are lowered during exercise in normal people by way of glycolysis. The need for energy from the cells causes your metabolism to rise, which in turn causes sugar to be pulled from the blood and into the tissue cells.
If your blood glucose level is over 250 mg/dl, then you’re likely hyperglycemic. This is a serious problem if you’re a diabetic, although normal people can have issues with this too if they don’t have enough insulin. Too much sugar in the blood can cause a diabetic shock if you start exercising. Basically, there’s all this sugar in the blood, you start exercising and you aren’t breaking down all that sugar floating around, and your body freaks out.
Most of these are really only issues that affect diabetics. If someone has a bad diet, however, this can also apply.
