Before exercising, your glucose levels should be around 100 to 200 mg/dl. Check your glucose levels before, during, and after the exercise program with a glucometer. Inject insulin in the area (limb) which is not being exercised at least one hour prior to exercise.

Diet is key in glucose regulation; seek out a nutritionist to ensure that you are eating for optimum health. Note that exercise can decrease your need for insulin or oral hypoglycemic agents.

High blood glucose (hyperglycemia) is a blood glucose greater than 250 to 300 mg/dl with symptoms of increased urine, thirst, nausea, and rapid pulse. Allow your glucose level to fall to normal before exercising. Low blood glucose (hypoglycemia) is a blood glucose of 60 to 70 mg/dl or less, with symptoms of headache, nausea, irritability, and extreme hunger. If glucose level is less than 100 mg/dl, ingest carbohydrates before exercising. Always carry with you fast-acting glucose foods, such as raisins, fruit juice, sugar cubes, or Life Savers�. Additionally, eat complex carbohydrates, such as crackers.
