According to the latest data from the International Diabetes Federation, China has more than 92 million adults with diabetes, surpassing India and becoming the world’s number one diabetes-hit area. Obesity is the biggest cause of diabetes, and it has been proven that abdominal fat, in addition to storing energy, is also an active endocrine tissue that is the most direct cause of insulin resistance and ultimately leads to the development of diabetes. Therefore, controlling obesity, especially abdominal obesity, is an important part of controlling the onset and progression of diabetes. Bariatric surgery has resulted in the cure of 76.6% of obese type 2 diabetic patients and a significant improvement in 80% of primary hypertension. Limiting daily caloric intake, especially carbohydrates (rice, pasta, etc.), is a fundamental tool in the prevention and treatment of type II diabetes. Diet and exercise are important tools, but in practice it is often difficult to achieve the desired results. With the development of modern minimally invasive surgical techniques, surgical procedures can achieve rapid weight loss, no relapse, no sequelae, and can be basically scarless and non-invasive, and the patient’s privacy can be fully respected after surgery. The minimally invasive gastrointestinal surgery team of Aero Center Hospital, formed by expatriates and doctors, has carried out a safer and simpler gastric reduction surgery, namely gastric folding surgery, to treat obese patients and bring good news to obese patients with type II diabetes. The goal of the surgery is to improve the health and quality of life of severely obese people by reducing their body weight, helping to control blood sugar and increase longevity. There is a formula to measure whether the weight is overweight, that is, the body mass index (BMI, Body Mass Index = weight (kg) / height (m)2. If the weight is 75 kg and the height is 162 cm (1.62 m), the body mass index is: 75 ÷ 1.62 ÷ 1.62 = 28.6. Standard values of body mass index for adults in China: Light weight: BMI <18.5 The most ideal body mass index is 22; preoperative assessment, the indications for weight loss surgery are one of (1) to (4), and at the same time have (5) (8) (1) Morbid obesity (BMI over 30) or severe obesity (BMI over 35). (2) BMI of 28 or more combined with obesity complications. (3) Waist circumference: ≥90 cm for men and ≥80 cm for women. (4) Failed medical attempts to reduce weight. (5) Age between 14 and 65 years. (6) No exclusion of hypothyroidism and Cushing's syndrome. (7) No major psychiatric disorders, no narcolepsy or substance abuse. (8) No serious abnormalities of major organ function and acceptable surgical risk.
