Is there any exercise I should avoid?

If you have diabetes complications, some kinds of exercise can make your problems worse. For example, activities that increase the pressure in the blood vessels of your eyes, such as lifting heavy weights, can make diabetic eye problems worse. If nerve damage from diabetes has made your feet numb, your doctor may suggest that you try swimming instead of walking for aerobic exercise.

When you have numb feet, you might not feel pain in your feet. Sores or blisters might get worse because you don’t notice them. Without proper care, minor foot problems can turn into serious conditions, sometimes leading to amputation. Make sure you exercise in cotton socks and comfortable, well-fitting shoes designed for the activity you are doing. After you exercise, check your feet for cuts, sores, bumps, or redness. Call your doctor if any foot problems develop.
