Diabetes and Heart Disease

How Diabetes and Heart Disease Are Related

Diabetes and heart disease are related. Chronic high blood sugar in diabetics leads to narrowed arteries, higher triglycerides, high blood pressure, and lower levels of HDL, the "good" cholesterol. These all lead to increased risk for heart disease, including heart attack and stroke.

Type 2 diabetes is the most common form of diabetes. Unfortunately, there are many people who have the disease but have not been diagnosed. Diabetes, regardless of type, requires treatment in order to minimize the risk of heart disease and other health complications. Untreated diabetes can lead to more severe atherosclerosis and it may occur at an earlier age.

Another complication occurs when diabetes has also caused nerve damage. Nerve damage can block or decrease the sensation of pain that would normally occur with a heart attack. As a result, symptoms of the heart attack may not be recognized, and may be thought to be something much less serious, such as an upset stomach.

To minimize your risk of heart disease:

If you notice signs of diabetes or you are in a higher-risk group (see: What Causes Diabetes?), make an appointment with your doctor to be screened. A simple blood test can determine whether or not you are diabetic.

Keep blood glucose levels tightly controlled. A diabetes treatment plan will include a healthy diet, regular exercise, and in some cases, oral medications or insulin may also be needed. Check your blood glucose levels regularly to make sure they stay within the target range set by your doctor.

Improve your cholesterol levels. LDL, or the "bad" cholesterol, should be lowered since it can clog arteries, leading to heart disease. HDL is the "good" cholesterol and it helps to keep your arteries clear.

You can improve your cholesterol levels by losing weight, limiting the amount of fatty foods you eat, and leading an active lifestyle. Many cookbooks of "heart- healthy" meals and snacks are available. For some people these steps may not be enough and medications are available to help control cholesterol levels.

Keep blood pressure under control. Diabetics are at increased risk for high blood pressure, another risk factor for heart disease. Once again, diet and exercise can help to keep blood pressure in normal ranges. Alcohol consumption should be limited. Medications are also available.

Lose weight if you're overweight. People who carry extra abdominal fat are particularly at higher risk for heart disease. However, if you're overweight (regardless of where you carry the extra weight), losing weight will be beneficial. It can help lower high blood pressure and high blood glucose, and increase the body's sensitivity to insulin.

Be active. Get regular exercise (check with your doctor first to make sure it's safe). Try to exercise every day, or at least most days of the week. Exercise helps helps to control blood sugar, cholesterol, blood pressure, and aids in weight loss.

Don't smoke. Smoking can cause blood vessel damage. Combined with diabetes, it also doubles your risk of developing heart disease.

Diabetes and heart disease are related. Action is required to minimize the risk of developing heart disease. Your doctor and diabetes educator can help you create an individualized treatment plan to keep your diabetes under control and decrease the risk of diabetes-related complications.
