Anyone looking for a way to lose weight has probably heard of weight loss metabolic surgery (some people call it “gastrectomy”). We all look forward to it to get rid of the dilemma of “Hey, that fat guy”. But the thought of surgery brings up 10,000 points of worry. So, can we go for the surgery or not? 1. What kind of people are suitable for surgery? People who are already suffering from severe metabolic syndrome and cannot exercise to reduce weight, which seriously affects the quality of life and life safety. Dr. Youdao Group weight loss and metabolic surgery center has contacted a patient who delayed treatment after consulting weight loss and metabolic surgery and died suddenly in his sleep because of sleep apnea syndrome. Because the patient’s blood oxygen concentration was tested to be low, the director had asked the case manager to call the patient’s family several times to suggest entering respiratory care first, but the family did not pay attention, leading to a sad ending. In addition, patients need to meet some conditions, according to the Chinese Guidelines for the Surgical Treatment of Obesity (2007): Those who meet any one of the first three of the following and also have the fourth condition can perform weight loss surgery: 1. BMI ≥ 32 kgm2 2. Confirmation of the presence of metabolic disorder syndrome associated with obesity, such as: hypertension, diabetes, fatty liver, sleep apnea syndrome hyperlipidemia, etc., and the predicted weight loss is effective. 3, waist circumference: men ≥ 90cm, women ≥ 85cm; dyslipidemia. 4.Other: no alcohol or drug dependence, no serious mental and intellectual disabilities; other weight loss methods are ineffective or intolerable; 16-65 years old; understanding and acceptance of surgery and post-operative lifestyle changes 2.What is BMI? BMI body mass index reflects an important indicator of obesity, and is also the primary indication of whether type 2 diabetic patients and obese patients are suitable for metabolic surgery. BMI=weight kg÷height m÷height m For example, if a person weighs 70kg and is 1.7m tall, his BMI=70÷1.7÷1.7=24.22kg/㎡ 3.What is C-PeptideC-Peptide is mainly used to evaluate the function of pancreatic islets, which is secreted by pancreatic β-cells and can more accurately evaluate the secretion function of pancreatic β-cells. secretion function. The purpose of assessing islet function is that metabolic surgery to relieve or cure diabetes requires that the patient still has some islet function. For fasting serum C-peptide, it is generally required to be more than half of the lower limit of normal value, and for oral glucose tolerance test, the C-peptide level should rise to more than twice the basal level after 60 minutes of sugar intake. DurationofDM diabetes duration For the duration of diabetes, it is generally required that the type 2 diabetes is within 15 years; generally speaking, the shorter the duration of the disease, the less damage to the islet function, and the better the surgical effect. In addition, the doctor needs to understand the impact of obesity and metabolic disease on the patient’s whole body and the severity of concomitant type 2 diabetes through various tests of the patient, and make an assessment so as to develop a preoperative preparation plan.
