Insulin is a hormone that helps your body's cells get the energy they need from sugar. When insulin is not able to do its job, too much sugar builds up in your blood. Over time, this extra sugar in your blood can lead to problems with your eyes, heart, blood vessels, nerves, and kidneysClick here to see an illustration.. It also makes you more likely to get severe illnesses or infections. When diabetes causes other problems, they are called complications.

Diabetes and its complications can change your life. Living with health problems caused by diabetes can be an ongoing struggle.

What are the symptoms?

Your symptoms will vary depending on which complications you have.

  • Heart disease can cause chest pain (also called angina) or shortness of breath when you exercise. You may have other symptoms, such as dizziness or lightheadedness, shoulder or stomach pain, or a racing heartbeat. Some people don't have any symptoms until they have a heart attack or a stroke.
    • If the nerves related to feeling and touch are affected, it can cause tingling, numbness, tightness, burning, or shooting or stabbing pain in your feet, hands, or other parts of your body, especially at night. It is possible that you may not notice an injury, especially on your foot, until a severe infection develops. A bad foot infection can spread up your leg and into your bones. If this happens, the affected limb may need to be removed (amputated).
    • If the nerves that control internal organs are damaged, you may have digestion, bladder, or sexual problems. You may also sweat a lot or too little, feel dizzy or weak, or faint when you stand up. It may become hard to tell when your blood sugar is low.
  • Kidney disease may not cause any symptoms at first. As time goes on, you may have swelling in your feet and legs and, later, throughout your body. It can also cause high blood pressure over time.

How are they treated?

The treatment for complications focuses on stopping or at least slowing down the damage. Depending on the problem, treatment may include medicine, surgery, or other therapies. Early treatment for a complication can help slow the damage and may prevent other problems.

Here are eight steps that people with diabetes can take to help keep health problems from getting worse.

  1. Keep your blood sugar within your target range. Part of your daily routine includes checking your blood sugar levels regularly as advised by your doctor.
  2. Eat a balanced diet. And, if you are overweight, reduce your calorie intake so that you can lose some weight. Losing as little as 10 to 20 pounds can improve your blood sugar levels. There are many ways to manage how much and when you eat. Your doctor, a diabetes educator, or a dietitian can help you find a plan that works for you. Making these lifestyle changes may make you feel better and help control your blood sugar.
  3. Exercise regularly. Aim for at least 2½ hours a week of moderate activity. Exercise helps control your blood sugar by using glucose for energy during and after activity. It also helps you to stay at a healthy weight, lower your total cholesterol, raise your HDL (good) cholesterol, and lower high blood pressure.
  5. Don't smoke. Smoking increases your risk for heart attack, stroke, and many other serious problems.
  6. Control your cholesterol and keep your blood pressure lower than 130/80 by exercising regularly, eating a balanced diet, and taking medicine if necessary.
  8. Have routine checkups every 3 to 6 months (or more often if needed), and watch for signs of other problems. During these visits, your doctor will review your treatment and look for other problems. Also be sure to see your eye doctor and dentist regularly.
