Why Do Blood Glucose Levels Sometimes Go Up after Physical Activity?
When you exercise your muscles need more glucose to supply energy. In response, your liver increases the amount of glucose it releases into your bloodstream. Remember, however, that the glucose needs insulin in order to be used by your muscles. So if you do not have enough insulin available, your blood glucose levels can actually increase right after exercise. Basically, stimulated by the demand from your exercising muscles, your body is pouring glucose into your bloodstream. If you do not have enough insulin available to "unlock the door" to your muscles, the glucose cannot get into your muscles to provide needed energy. The end result is that glucose backs-up in your bloodstream, causing higher blood glucose readings.
Exercises to Lower Your Blood Sugar
How It Works
When you do moderate exercise, like walking, that makes your heart beat a little faster and breathe a little harder. Your muscles use more glucose, the sugar in your blood stream. Over time, this can lower your blood sugar levels. It also makes the insulin in your body work better. You'll get these benefits for hours after your walk or workout.
Just remember you don’t have to overdo it. Strenuous exercise can sometimes increase blood sugar temporarily after you stop exercising. Very intense exercise can cause the body to make more stress hormones which can lead to an increase in blood sugar.
