Many patients who come to our hospital for diabetes treatment ask if diabetes can really be treated surgically. I can answer in the affirmative, but only if there are some strict conditions, which is what we call the indications for surgery. In fact, this surgery is a gastrointestinal surgery, the basic principles of which are: 1, reduce the intake and absorption of food, thus reducing energy intake and glucose metabolic load; 2, reduce the patient’s weight and reduce insulin resistance caused by fat accumulation due to simple obesity; 3, the gastrointestinal tract reconstruction has changed the intestine-insulin axis hormone food secretion, thus improving glucose metabolism. Gastric diversion surgery for type 2 diabetes has actually been written into the diabetes treatment guidelines long ago, and in foreign countries it was even written into the guidelines of internal medicine 10 years ago. In China, surgery for obese type 2 diabetes has become a medical-surgical consensus, and for overweight friends who have poor glycemic control can also choose surgery, and if your BMI > 27.5 and your glycemic control is poor, it is recommended that you have surgery, because after surgery About 80% of patients are free from drugs and return to full normal. As we can see from the 2nd International Forum on Weight Loss and Metabolic Surgery, surgery for diabetes has become the most effective treatment both abroad and on the mainland, far surpassing the effectiveness of medical medication. Of course, many people still have a lot of doubts about this surgery, worrying about the safety and nutrition of the surgery. In fact, this surgery has been carried out in many cases in our hospital, until now there are no serious complications, recovery is smooth, and you can be discharged 3 days after surgery. What is type 2 diabetes? Type 2 diabetes, formerly known as adult-onset diabetes, mostly develops after the age of 35 to 40 and accounts for more than 90% of diabetic patients. Some patients with type 2 diabetes are mainly insulin resistant. Patients are mostly obese and have decreased insulin sensitivity due to insulin resistance and increased insulin in the blood to compensate for their insulin resistance, but insulin secretion is still relatively insufficient compared to the patient’s high blood sugar. Early symptoms in such patients are not obvious, with only mild weakness and thirst, and macrovascular and microvascular complications can often occur before a definite diagnosis is made. Dietary therapy and oral hypoglycemic drugs can be mostly effective. Diabetic surgery: Gastric diversion surgery was first used in bariatric surgery, and then it was found that obese patients with type 2 diabetes improved their diabetic symptoms after the surgery. After several years of clinical practice, doctors unexpectedly found that this surgery could effectively treat diabetes, thus gastric diversion surgery brought a new gospel for diabetic patients.
