Can diabetes cause congestive heart failure?

[tanyajack]

In healthy people, insulin keeps the blood sugar level relatively constant. However, for those vulnerable to type 2 diabetes, the body gradually loses its sensitivity to insulin. This leads to chronically elevated blood sugar levels, also known as impaired glucose tolerance. Uncontrolled diabetes can damage the artery walls and contribute to coronary heart disease. People who are obese are more likely to develop type 2 diabetes than people of normal weight. Australian Aboriginal and Torres Strait Islander peoples have much higher rates of diabetes than other Australians, even at lower body weights.
