1, genetic factors. Many people think that type I diabetes is hereditary. In fact, type II diabetes is more hereditary. People with a family history of diabetes need special attention.

2. Obesity. Obesity is the most important inducing factor of diabetes, and it is related to the distribution of body fat. Central obesity, that is, having a big belly, has the greatest relationship with diabetes. In addition, this correlation is greater for men than for women. In other words, a man with a big waist and a big belly is the most dangerous sign of diabetes.

3. High-fat diet. There are many studies in this field, and it is basically clear that high fat intake, especially high saturated fat intake, will greatly increase the incidence of diabetes.
