Certain types of exercises can be harmful for diabetics. So, it is necessary that you speak to your doctor before starting an exercise program and undergo diagnostics like a treadmill test. Your doctor would then be able to tell you what kind of exercises you need to avoid. Diabetics should choose those exercises, which fit easily in their routine. Uniform intensity of exercise is vital as it allows you to maintain adequate blood sugar levels.
Your blood sugar level may drop or rise beyond acceptable levels during exercise. It is recommended that you have someone monitoring you while you exercise as you may need help. Never overdo the exercises, and if you have to build on intensity, do it in a stepwise fashion gradually over a few days. Ensure that you check your blood sugar levels before and after exercise. The blood glucose in your body varies with exercise and if unmonitored you might be inviting diabetic ketoacidosis leaving you dangerously dehydrated.
If you have ketones in your urine and the blood sugar level is over 250 mg/dL (milligrams per deciliter) 8 hours after consuming food, refrain from exercise. If the sugar level is 300 mg/dL without ketones in your blood, exercise with caution. Low blood sugar is also not good before you set out to exercise. If the level is below 100 mg/dL, eat a carbohydrate snack, and if it is below 70 mg/dL, avoid going to the gym.
