First of all, diabetes is just a general term for a group of metabolic diseases characterized mainly by high blood sugar, under which there are four types. type 1, type 2. Pregnancy type and other types. Type 1 diabetes: is an absolute lack of insulin, referring to the pancreatic secretion of insulin beta cells, generally affected by autoimmune dysfunction, and also related to a variety of factors such as genetics and the environment. type 1 diabetes is mainly developed in adolescents, the onset is mostly concentrated in the 12-14 weeks of age, and requires insulin injection therapy. This type of diabetes has little hope for a successful cure and requires lifelong medication or insulin injections. Type 2 diabetes: The most common form of diabetes, 95% of which is type 2 diabetes. The pathogenesis of this disease is mainly insulin resistance or relative insulin deficiency. It can be treated with oral medication and insulin. In addition to the traditional medical treatment, surgical weight loss and glucose reduction surgery can also be used to treat the disease. The therapeutic effect of diabetes surgery is to improve blood glucose and metabolic disorders in the near term and to reduce diabetes-related complications in the long term. The rate of complete clinical remission (clinical cure rate) for patients who meet the criteria for surgery is over 80%, partial remission rate is 15%, and the overall effective rate is over 95%. Other special types of diabetes: such as cholesterol diabetes and pancreatogenic diabetes, can also be treated with drugs and insulin, and in case of metabolic disorders caused by obesity, complete remission can be achieved through weight loss surgery. Gestational diabetes: It is when a woman is pregnant and detects diabetes, treatment is not recommended with oral medication, but insulin treatment is recommended to lower blood sugar. Usually the woman’s blood glucose returns to normal after she is out of breastfeeding, and some of them will transform into type 2 diabetes, in which case traditional medical treatments and weight loss metabolic surgery can also be taken. In summary, diabetes cannot be completely cured. It is important to choose the appropriate treatment plan according to different types of diabetes, follow medical advice and take medication on time so as to prolong life and improve quality of life.
