If You Have Diabetes, It Can Increase Your Risk of Heart-Related Issues, but These Tips Can Help
It's no secret that managing blood sugar levels is a key part of staying healthier when you have diabetes. But do you know why keeping blood sugar under control is so important? High blood sugar can take a toll on many parts of the body over time, especially the heart. In fact, people with diabetes are at a much higher risk for heart disease and stroke than those without the condition.
The connection between diabetes and heart health may not seem obvious, but understanding it can help you make choices that protect your heart for years to come. Here is some insight into how diabetes can affect your heart, as well as what you can do to keep your heart healthier.
How diabetes affects your heart
Diabetes creates changes in your blood vessels and circulation that may result in:
- Blood vessel damage. High blood sugar can injure the lining of the large blood vessels that provide circulation to your heart and brain. Over time, they can become stiff or narrowed, which makes it harder for blood to flow freely. This increases the risk of heart attacks and strokes.
- Weakened heart muscle. Diabetes also causes narrowing of the small blood vessels going directly to the heart muscle, making it harder for the heart to pump blood effectively. This can lead to heart failure, which may cause fatigue, swelling and shortness of breath.
- Other health issues. People with diabetes often also have high blood pressure, high cholesterol or obesity. Each of these conditions adds strain to the heart and speeds up damage.
Because diabetes can damage nerves, some people don't feel classic warning signs of heart trouble, such as chest pain. That means heart disease may be more advanced by the time it's discovered.
Steps you can take to protect your heart
The good news is that while diabetes raises your risk of developing cardiovascular issues, there's a lot you can do to protect your heart. Small daily habits make a big difference and these tips can help:
- Keep blood sugar in range. Monitoring your levels, following your care plan and taking medications as prescribed all help prevent damage to your blood vessels.
- See your doctor regularly. Routine visits give your care team a chance to check your blood pressure, cholesterol and kidney health, as well as run tests to spot heart problems early.
- Eat with your heart in mind. Fill your plate with fruits, vegetables, whole grains, lean proteins and healthy fats. Cutting back on processed foods and sugary drinks helps too.
- Stay active. Moving your body helps in many ways. It improves how you use insulin, lowers blood pressure, helps control weight and boosts overall heart health. Even a daily walk counts.
- Maintain a healthy weight. Losing even a small amount of weight can improve blood pressure, cholesterol and blood sugar levels, all of which lighten the load on your heart.
- Quit smoking. Smoking damages blood vessels and speeds up heart disease. Quitting is one of the best things you can do for your heart and overall health.
- Manage stress. Chronic stress can raise blood pressure and make healthy habits harder to follow. Find ways to relax, such as deep breathing, meditation or talking with friends.
Diabetes may raise your risk for heart problems, but by understanding the connection and taking steps to manage your health, you can keep your heart stronger. Focus on what you can control — like blood sugar management, diet, activity and stress reduction — and partner with your doctor to stay on track. Small choices add up, and each step you take is a step towards a healthier heart now and in the future.
