The relationship between diabetes and heart health is significant. People with diabetes are at a higher risk of developing heart disease, which can lead to serious complications like heart attacks or strokes. High blood sugar levels can damage blood vessels and nerves that control the heart, making it essential to manage diabetes effectively. Regular check-ups with your GP and lifestyle changes, including a healthy diet and regular exercise, can help reduce the risk of heart problems. The NHS emphasizes the importance of monitoring your heart health as part of diabetes management.
