- Your feet and skin can develop sores and infections. If it goes on too long, your foot or leg may need to be removed. Infection can also cause pain and itching in other areas.
- Diabetes may make it harder to control your blood pressure and cholesterol. This can lead to heart attack, stroke, and other problems. It can become harder for blood to flow to the legs and feet.

Take Control of Your Diabetes
It is important to keep your blood sugar, blood pressure, and cholesterol in a healthy range. You should learn the basic steps for managing diabetes and staying as healthy as possible.

All these may help you keep complications of diabetes away.
You will need to check your blood sugar level to see how you are doing.
