Diabetes mellitus is a common endocrine metabolic disease, of which type 2 diabetes is the most prevalent. Currently, the incidence of type 2 diabetes is on the rise worldwide and has become a serious threat to people’s lives. According to statistics, there are about 113.9 million Chinese adults suffering from diabetes, and the percentage of overweight or obese people reaches 65%, about 74.4 million. Obviously, obese people are more likely to get diabetes, but why is that? If you want to know why you have diabetes, you have to know the principle of diabetes. Diabetes is a group of metabolic diseases characterized by high blood sugar. In the case of the most common type 2 diabetes, the insulin produced by the patient’s body is less effective and cannot effectively suppress blood sugar, resulting in high blood sugar. In normal people, blood glucose rises temporarily for a period of time after eating, when the body begins to secrete insulin, which, through insulin receptors, stores excess glucose and suppresses glucose production, bringing blood glucose values back to normal levels. In type 2 diabetes, because insulin is not strong, it can neither effectively prevent glucose production nor convert most of the excess glucose into storage, resulting in high blood glucose and glucose loss. One of the main reasons why blood sugar tends to rise in obese people is that he has more fat cells, but the number of insulin receptors carried by itself is relatively fixed, and as more and more fat is added, the receptors are relatively reduced, thus leading to a decrease in insulin sensitivity to blood sugar. In order to reverse this situation, the pancreas began to work non-stop to speed up the release of insulin, but over time, the pancreas collapsed, the function also failed, and finally can not effectively inhibit the rise of blood sugar, also suffered from diabetes. In addition, most of the obese people do not like to exercise, and often overeat, which is very unfavorable to the internal metabolic system of the body, it is easy to cause blood sugar to rise. Even if at first all body functions are still normal, and so on time, the metabolic system will be overwhelmed, and eventually evolved into diabetes, fatty liver, high blood pressure, high blood pressure and other diseases. So fundamentally, in addition to special causes such as congenital heredity, diabetes has a great deal to do with one’s lifestyle habits. The two habits of inactivity and overeating make the body fat and overwhelm it, and various diseases come slowly. Especially after the age of 40, the body functions are going downhill, the risk of morbidity is greater. See here you are still hesitant to lose weight? You should know that weight loss is not only to add points to the appearance, but also to reduce the burden on the body, so as to live a healthier life, after all, there is a good body to live a more exciting life.
