What is the link between high blood sugar and heart disease?

High blood sugar, or hyperglycemia, can significantly increase the risk of developing heart disease. When blood sugar levels are consistently high, it can lead to damage in the blood vessels, increasing the likelihood of atherosclerosis, where arteries become narrowed and hardened. This condition can result in a heart attack or stroke. It's especially important for British South Asians, who have a higher prevalence of diabetes, to monitor their blood sugar levels regularly. The NHS provides resources and support for managing diabetes effectively, which can also help in protecting heart health.
