Diabetes and the Exercise Effect

You have experienced the 'Exercise Effect' on blood sugar levels.
How Exercise Affects Blood Sugar Levels
Blood sugar levels change throughout the day for all of us. We may wake up with low sugar, which is eased by a healthy breakfast containing fiber and protein. After lunch our sugar levels might rise a bit, and by late evening we usually have our highest readings of the day. This pattern of blood sugar increase is common to the diabetic, the pre-diabetic and the non-diabetic alike, although the levels are generally highest for the diabetic.
These changing levels are responsive to the demands we place on ourselves each day. If we remember that our bodies utilize glucose to create energy, that pattern makes sense. The more active we are through the day, the greater the demands for glucose.
For the person with diabetes, there is impairment of either the release of insulin by the pancreas or the acceptance of insulin by the cells, or both. Because of this, the amount of insulin circulating in the bloodstream is insufficient to cause the cells to accept all of the glucose the body produces.
When we exercise, the body demands even more glucose than usual for its exercising muscles. The liver responds to this increased demand and releases glucose. Without receiving any additional insulin, the glucose is not processed into the body' Continue reading
