Obesity has now become one of the main causes of type 2 diabetes. A number of studies have proven that excess fat can lead to increased insulin resistance, making insulin less effective and forming diabetes, so for obese diabetics, weight loss can better control blood sugar. However, it is more difficult for diabetic patients to lose weight compared with ordinary people. Diabetic patients are more sensitive to exercise and diet because of their lack of blood glucose regulation, and excessive exercise or insufficient diet is likely to cause hypoglycemia, so they are naturally limited in the way and intensity of weight loss. Moreover, some glucose-lowering drugs have the side effect of fattening. After the use of glucose-lowering drugs, the utilization of glucose will be enhanced to a certain extent, which will be converted into fat, protein and other substances by the body, resulting in weight gain. Diabetics need to do more than ordinary people not only to lose weight successfully, but also to learn a multi-pronged approach, with a light diet and timely correction of bad habits. If obesity reaches a certain level you can also choose weight loss metabolic surgery to lose weight. This surgery not only allows obese diabetics to lose a lot of excess weight, but also helps them to better control their blood sugar by restricting their diet and absorption to directly reduce a portion of their blood sugar. In the case of obese type 2 diabetics, as long as they still have some insulin secretion, they can also reverse their diabetes with weight loss metabolic surgery. This surgery is now very mature, and more than one million people around the world undergo weight loss metabolic surgery each year. In China, more than 10,000 patients get rid of obesity or diabetes through this surgery each year, and special personnel are needed to provide post-operative guidance to patients after the surgery to eliminate their worries.
