What causes diabetes

1. Genetic factors: diabetes has familial genetic susceptibility. However, the heredity still needs the effect of external factors, which mainly include obesity, reduced physical activity, unreasonable diet structure, virus infection and so on.

2. Obesity: obesity is an important cause of diabetes. Especially easy to cause type 2 diabetes. Especially abdominal obesity. The main mechanism is that obese people have obvious hyperinsulinemia. Hyperinsulinemia can reduce the affinity between insulin and its receptor, resulting in the inhibition of insulin action and insulin resistance.

3. Lack of activity: physical activity can increase tissue insulin sensitivity, reduce weight, improve metabolism, reduce insulin resistance, relieve hyperinsulinemia and reduce cardiovascular complications. Therefore, the decrease of physical activity has become an important factor of type 2 diabetes.
