Diabetes and Your Heart

Diabetes and Your Heart

Diabetes and heart disease often go hand in hand. Learn how to protect your heart with simple lifestyle changes that can also help you manage diabetes.

Heart disease is very common and serious. It’s the leading cause of death for both men and women in the United States. If you have diabetes, you’re twice as likely to have heart disease or a stroke than someone who doesn’t have diabetes—and at a younger age. The longer you have diabetes, the more likely you are to have heart disease.

But the good news is that you can lower your risk for heart disease and improve your heart health by changing certain lifestyle habits. Those changes will help you manage diabetes better too.

How Diabetes Affects Your Heart

Over time, high blood sugar can damage blood vessels and the nerves that control your heart. People with diabetes are also more likely to have other conditions that raise the risk for heart disease:

High blood pressure increases the force of blood through your arteries and can damage artery walls. Having both high blood pressure and diabetes can greatly increase your risk for heart disease.

Too much LDL (“bad”) cholesterol in your bloodstream can form plaque on damaged artery walls.

High triglycerides (a type of fat in your blood) and low HDL (“good”) cholesterol or high LDL cholesterol is thought to contribute to hardening of the arteries.

None of these conditions has symptoms. Your doctor can check your blood pressure and do a simple blood test to see if your LDL, HDL, and triglyceride levels are high.

These factors can also raise your risk for heart disease:

· Smoking

· Being overweight or having obesity

· Not getting enough physical activity

· Eating a diet high in saturated fat, trans fat, cholesterol, and sodium (salt)

· Drinking too much alcohol

People with diabetes are also more likely to have heart failure. Heart failure is a serious condition, but it doesn’t mean the heart has stopped beating; it means your heart can’t pump blood well. This can lead to swelling in your legs and fluid building up in your lungs, making it hard to breathe. Heart failure tends to get worse over time, but early diagnosis and treatment can help relieve symptoms and stop or delay the condition getting worse.
