Cardiovascular disease (CVD) is a long-term complication of type 1 diabetes (T1D).

CVD includes coronary heart disease, cerebrovascular disease, and peripheral artery disease. Chronic high blood sugar and other risk factors can affect blood vessels, placing people with T1D at a higher risk of developing cardiovascular disease.

T1D and cardiovascular disease

Cardiovascular disease is increasingly understood to be an important health issue for people with T1D. Risk factors that can lead to CVD include high blood sugar, high blood pressure, and kidney disease.

Additionally, despite the common (mis)perception that people with T1D are lean, the T1D population lives with obesity—another CVD risk factor—at rates comparable to non-diabetic people.

High blood sugar is one reason CVD is more common and occurs at an earlier age in people with T1D, but there may be other features of T1D that accelerate CVD which are yet to be discovered.

Preventing cardiovascular disease

For people living with T1D, eye disease is a troubling reality, but early detection and timely treatment can reduce the risk of blindness by over 95 percent.



Nearly one out of three people with T1D develop kidney disease. Fortunately, most people with T1D and kidney disease don’t end up with kidney failure.
