In addition to reducing the amount of food consumed, the appetite stimulating hormone Ghrelin is also reduced, thus reducing the appetite. Within two years after surgery, you can lose about 10-15 BMI or 70% of your excess weight. For those who have a high BMI (over 40) and have difficulty reducing their appetite, sleeve gastric surgery can achieve the desired weight loss. Method: 2-6 cm of the sinus above the pylorus is preserved in the direction of the greater curvature of the stomach, and the greater part of the stomach is removed along the long axis of the stomach, with the entire fundus removed, leaving a “banana-shaped” stomach with a volume of about 60-80 ml. Principle: To reduce the volume of the stomach and decrease the secretion of hormones that stimulate the production of hunger. Advantages: It does not change the physiological state of the gastrointestinal tract and does not interfere with the normal process of digestion and absorption of food. Evaluation: Sleeve gastrectomy has good therapeutic effect on type 2 diabetes, and is a widely used surgery for weight reduction and diabetes in the European Cup at present. Effectiveness of bariatric surgery: Studies have shown that patients who underwent bariatric and diabetic surgery were able to achieve complete glycemic remission in type 2 diabetics compared to those who underwent only conventional medication. Two years after undergoing gastric bypass, patients had a 75% diabetes remission rate answer. Diabetes remission definition: glycated hemoglobin In addition, weight loss with diabetes surgery significantly addresses or improves type 2 diabetes and other obesity comorbidities. Studies have shown that bariatric and diabetic surgery resolved or improved diabetes in 86% of patients, improved hyperlipidemia in 70% or more of patients, resolved or improved hypertension in 78.5% of patients, and resolved sleep apnea in 85.7% of patients. Along with blood sugar control, undergoing weight loss and diabetes surgery also reduces the use of medications for complications such as diabetes, hypertension, and hyperlipidemia, and provides varying degrees of improvement in patients’ overall health, emotional well-being, physical and social functioning, pain relief, and personal energy recovery. Applicable population for bariatric surgery: Type 2 diabetes mellitus duration ≤ 15 years, and islets still have some insulin secretion function, fasting serum C-peptide level ≥ 2/1 BMI ≥ 27.5 kg/m2 of the lower limit of normal. The recommended level of surgery can be increased at the discretion of men with waist circumference ≥ 90 cm and women with waist circumference ≥ 85 cm. Recommended age 16-65 years. Patients with a BMI between 25.0-27.4 kg/m2 need to be considered for surgery with caution. The above criteria, the doctor also needs to consider the patient’s metabolic syndrome group or the presence of comorbidities, please consult the doctor in detail.
