elevated Blood sugar levels after exercise
Why is it that sometimes my blood sugar levels rise after walking. First thing in the morning,about an hour after exercise and not eating anything my b/s level goes up by about 4-5 points.
star queen, you really need a class in exercise physiology
churchlady1, your blood sugar will vary, sometimes changing by 10-15 points, just based on normal human metabolism (stress, temperature, etc). Generally, low intensity exercise will decrease blood sugar. Higher intensity exercise (which sometimes can even be walking for some individuals who are deconditioned) can have a tendancy to increase blood sugar. Sometimes individuals can wake up with higher blood sugar due to what is referred to as "the dawn effect". This is a normal physiological state caused by the release of stress hormones early in the morning.
If you are diabetic, the general rule of thumb is that if your blood sugar is between 100-250 it is safe to exercise. If it is less than 100, eat 15 grams of carbohydrate, and recheck your blood sugar in 15 minutes. If your blood sugar is 250+ and you have urinary ketones present, delay exercise until it is below 250.
The reason why we don't want people exercising if their blood sugar is <100 is because they can go hypoglycemic.

When you exercise, the muscles in the body needs more energy to perform. If you have not eaten any food, sugar in the form of Lactose is secreted by the muscle to give the muscle the energy it needs. If this sugar is not used up during exercise, the sugar is still in the blood and will test higher for an hour or so before being used up by other bodily activities. If you eat before exercise, the sugar from the food intake will take care of the needs of the muscles and get used up before the muscle needs to secrete Lactose so the blood sugar in the blood will test lower. hope this helps
