Many people treat diabetes by relying mainly on glucose-lowering drugs and insulin to control blood sugar, in addition to life interventions. However, traditional medication can generally only temporarily control blood sugar and cannot effectively curb the progression of the disease, so many diabetics face a variety of complications in the late stages. Because of this, weight loss metabolic surgery, which is more effective and stable, is gradually coming into the public eye. The principle of surgical treatment: Diabetes surgery is also known as weight loss metabolic surgery, and the more commonly used procedure is gastric bypass surgery. Gastric bypass surgery is a reconstructive surgery of the gastrointestinal tract that restricts the patient’s diet and absorption capacity by displacing a portion of the stomach and intestines, and has a very good effect on weight loss and blood glucose reduction for more than 50 years. Research over the years has shown that the mechanism of its treatment of diabetes has the following four main points. 1.Reducing weight and lowering insulin resistance 2.Limiting diet and absorption to control blood sugar 3.Changing gastrointestinal hormone secretion to improve glucose metabolism 4.Changing intestinal flora to directly lower part of blood sugar Unlike traditional drug therapy, surgical treatment solves the insulin resistance caused by obesity, and also directly lowers part of blood sugar, allowing patients to complete blood sugar regulation by themselves, which is equivalent to allowing patients to return to The effect is better and more stable than medication, and because of this, more and more people are choosing surgery to treat diabetes.
