Diabetes and heart disease
What is heart disease?
Heart disease is a group of diseases which can arise when blood vessels become so narrow that the amount of oxygen-rich blood reaching the body’s organs is reduced. Diabetes increases the risk of heart disease because high blood glucose levels can damage the walls of blood vessels. This damage can increase the likelihood of fatty material (such as fat and cholesterol) in the blood vessels and eventually, the build-up of fatty material can cause the vessels to become narrow. This, in turn, can lead to reduced blood flow.
When this happens, there can be a lot of force pushing the blood against the walls of the blood vessels, which is also known as high blood pressure. When your blood pressure is high, your heart and the blood vessels have to work a lot harder to move blood around the body. Over time, this causes damage to the heart and can lead to events like irregular heartbeat, heart attack or stroke.
What causes blood vessels to narrow or clog?
- High blood pressure
- High cholesterol
- Drinking too much alcohol
- Not eating a healthy diet
- Not getting enough exercise
Lowering your risk
If your type 2 diabetes is well controlled, then your risk for developing heart disease is reduced. Type 2 diabetes is a lifelong disease. Taking care of both your diabetes and heart health in the long-term involves eating a healthy diet, exercising regularly and monitoring your blood glucose levels.
