Follow a healthy lifestyle with proper diet and exercise. Keep the blood glucose levels as near to normal as possible. High levels of blood glucose may damage large blood vessels over time. High levels of blood insulin may also cause harm for people with type 2 diabetes. Keeping the blood glucose levels in the normal range can prevent or delay blood vessel damage.
Smoking narrows blood vessels over time and also increase the levels of fats in the blood.
Control blood pressure. High blood pressure can be an early warning sign of blood vessel damage. Blood pressure should be checked regularly. Losing weight and cutting salt from the diet can lower blood pressure. If the blood pressure is very high, medication should be had.
