Diabetes And Exercise

Tweet People with diabetes are encouraged to exercise regularly for better blood sugar control and to reduce the risk of cardiovascular diseases. The reason for this is that muscles which are working use more glucose than those that are resting. Muscle movement leads to greater sugar uptake by muscle cells and lower blood sugar levels. Additional benefits of exercise include a healthier heart, better weight control and stress management. Exercise is the common term used to describe any bodily activity that enhances or maintains physical fitness and overall health and wellness. Why is exercise important? As well as strengthening the cardiovascular system and the body’s muscles, many people exercise to keep fit, lose or maintain a healthy weight, sharpen their athletic skills, or purely for enjoyment. Frequent and regular physical exercise is recommended for people of all ages as it boosts the immune system and helps protect against conditions such as: Heart disease Stroke Cancer and other major illnesses In fact, it is known to cut your risk of major chronic illnesses/diseases by up to 50% and reduce your risk of early death by up to 30%.

    Does anybody know what kind of an effect exercise has on your fasting blood glucose levels? Specifically, I mean, what if you were to do a crossfit workout and then 20 minutes later get your blood drawn for a lipid analysis and fasting glucose level test. Would your blood glucose be higher (I'm thinking that your body is metabolizing lipids AND glucose to fuel the workout and there could be some extra glucose still floating around in the blood stream.)
    Also, what happens if you fast for say, 9 hours, instead of 12? Are the levels likely to be that much higher, do you think?

    Many factors involved. Diabetic? If so, type 1 or type 2. On insulin?
    In nondiabetics glucose levels can remain fairly constant. Type 1s (or type 2s taking insulin) may have an increased risk of exercise-induced hypoglycemia.
    Basically, during exercise (up to around the first 25-30 minutes), the body decreases insulin secretion and increases glycogen breakdown into glucose to meet the increased energy demands.
    The problem with insulin-dependent diabetics is that since they are injecting insulin, the body has no way of downregulating insulin secretion. This means less glycogen is broken down into glucose. The result? Low blood sugar or possibly hypoglycemia.
