Blood sugar is controlled by insulin in the body, but due to impaired pancreatic function, blood sugar cannot be controlled. Thus causing diabetes. The damage to the pancreas is irreversible. So, is diabetes “incurable”? It is not an incurable disease. Diabetes is divided into congenital (type 1 diabetes) and acquired (type 2 diabetes). Patients with congenital pancreatic dysfunction and acquired pancreatic function damage can only rely on medication or (and) insulin to maintain their condition. However, more than ninety percent of diabetics in China are acquired. Moreover, the vast majority are caused by obesity. Obese patients have high blood sugar themselves, then the pancreas has to work overtime to provide more insulin to maintain normal blood sugar in the body. The amount of insulin secreted is not linearly related to the amount of blood sugar, and more insulin has to be secreted to maintain it. This situation continues for a long time, many “pancreas” are exhausted. Therefore, in obesity with diabetes in the early stages, the pancreas has at least half of the normal function. Weight loss can “small horse-drawn cart” to let the pancreas low-speed operation, to maintain normal blood sugar. Maybe you can get rid of insulin or even drugs. Some of my friends who smoked had an opportunity to quit because they had pneumonia or emphysema. People with early diabetes caused by obesity also need to change their weight so that they can regain their health. Weight loss surgery can help to lower blood sugar in some cases, but it is also an opportunity. It is also an opportunity to change one’s lifestyle and diet. This can lower blood sugar and even get rid of diabetes.
