Diabetes: it is a systemic metabolic disease characterized by chronic hyperglycemia caused by a variety of reasons.

It is mainly caused by the defect of insulin secretion or insulin action, which will lead to the metabolic disorder of glucose, fat and protein in the body, thus causing multi system damage.


The etiology and pathogenesis of diabetes are extremely complex and have not yet been fully defined. In general, genetic factors and environmental factors (including age, lifestyle, lack of exercise, etc.) jointly lead to the occurrence of diabetes.

3 stages to go through:

The first stage: the stage of normal glucose tolerance, but there have been pathological and physiological changes related to diabetes;

The second stage: abnormal glucose tolerance stage (i.e. pre diabetes), a metabolic state between normal blood glucose and diabetes;

The third stage: diabetes.

Harm to human body:

The obvious feature of diabetes is hyperglycemia, and long-term hyperglycemia can bring various hazards to the body, such as:
