We are all familiar with obesity and diabetes. Nowadays, the number of obese people in China and the world is increasing rapidly, and diabetes has become a common disease, becoming the second killer among diseases that now obscure human health! The number of people suffering from diabetes is also increasing year by year! Many people do not know the relationship between diabetes and obesity, they are like “blood brothers”. Studies have shown that obesity is one of the most important risk factors for the development of type 2 diabetes. In people who are chronically obese, the prevalence of diabetes increases significantly, up to four times that of the general population. On the other hand, among type 2 diabetics, 60% are obese. Moreover, the longer the time of obesity, the greater the chance of diabetes. Also, the risk of diabetes for people with abdominal type obesity is much greater than for people with hip type obesity, because the waist-to-hip ratio is proportional to the incidence of diabetes, which means that people with large waists and small hips have a greater chance of developing diabetes, and people with large bellies should be more cautious. So why are obese people prone to diabetes? The fundamental reason is that there is a state called insulin resistance in the body of obese people. Insulin is the main blood sugar-lowering hormone in the human body. After eating, people absorb a large amount of sugar into the bloodstream and transport it to all parts of the body through blood circulation. Only by relying on insulin can blood sugar enter the cells and be used by the body, while the level of glucose in the blood is maintained within a certain range by insulin. However, this series of processes goes wrong in obese patients: the number of insulin receptors on the cell surface is reduced, and the function of individual receptors is also reduced and impaired. For various reasons, the cells become resistant to the action of insulin, and it becomes difficult for glucose from the blood to enter the cells. This is the phenomenon of insulin resistance. According to studies, effective weight loss can prevent the onset of diabetes or significantly reduce the degree of diabetes. For now, weight loss surgery is the most effective way to reduce weight in obese people and maintain it over time, and to alleviate a range of metabolic diseases such as diabetes.
