MedicineNet.com - Diabetes and Exercise

Diabetics need to check their blood sugar before and after exercising. Diabetics who do not check their blood sugar run the risk of hypoglycemia which can cause dizziness, as well as other complications. Just because you are a diabetic doesn't mean you can't exercise. But it is important to check with your doctor before beginning any exercise program, especially if you are over the age of 35 and run the risk of heart complications.
