    Case

    "Big fat" becomes "little fat" and stepped on the "red carpet"

    A year ago, Xiao Pan was ready to talk about marriage with his girlfriend. But his girlfriend is very dissatisfied with his body shape: he is 170 cm tall and weighs 120 kg. But Xiao Pan himself has always disagreed. His girlfriend issued an ultimatum: "If you don't lose weight, you won't get married! My groom must have a good figure at the wedding!" Then he made up his mind to lose weight.

    Expert analysis

    Stomach band weight loss surgery, the full name of laparoscopic gastric band weight loss surgery, is based on the principle of tying a band on the upper end of the stomach to divide the stomach into a pattern of "small upper and larger lower", which can really function as stomach Yes, it's just a small part of the upper part of the stomach, and most of the lower part of the stomach is only used as a digestive channel. In this way, after a small amount of food, the upper part of the stomach will be filled, which will produce a feeling of fullness, and the patient will stop eating, thereby achieving a weight loss effect. Therefore, people who lose weight through gastric banding surgery will no longer feel hungry, and it is especially suitable for simple obese patients who overeating or overeating causes fat accumulation.

    The placement of the gastric band adopts the minimally invasive technique of laparoscopy. It only needs to make two small holes in the abdomen. The trauma is small and the hospital stay is short. Generally, you can be discharged after 5-7 days after the operation. The biocompatibility of the strap is guaranteed. The material used is polyurethane. It has passed the international implant material test and passed the US FDI certification. It has been used internationally for more than 20 years without any serious problems. Therefore, Can stay in the body for a long time.

    Of course, if the patient has a need for further nutritional intake, such as a woman who needs additional nutrition and energy during pregnancy, the band can be removed at any time, because the operation is reversible.

    Q&A

    "Rehabilitation": What is the long-term effect of gastric banding surgery?

    Gu Yan: According to related research reports, within two years after gastric band surgery, most obese patients can lose half of their excess weight. However, we need to clearly realize that gastric band surgery is only a stage in the weight loss process, and it is an auxiliary means to help patients to control their diet and lose weight. If the patient has difficulty in self-control after the operation and does not stop eating after feeling full, then the lower part of the stomach, which is the digestive channel, will still play the role of digestion and absorption of food, which will greatly reduce the long-term weight loss effect. Therefore, the patient's compliance and self-control to the doctor's orders still play an important role in the process of weight loss. We do not recommend that young people under 18 years of age who are underdeveloped and those with food addicts undergo this operation.

    "Rehabilitation": Who are the suitable people for gastric band surgery?

    Wang Bing: Gastric band surgery is suitable for patients with simple obesity and severe metabolic disorders caused by it, such as diabetes, apnea syndrome, cardiovascular disease, bone and joint disease, hyperlipidemia and other diseases. There are no restrictions on age and gender. Recently, the Surgery Branch of the Chinese Medical Association has standardized the obese people for gastric band surgery, that is, BMI (body mass index: weight/height 2)>32, and those with other metabolic comorbidities, BMI>28. In addition, for men and women, there are specific waist circumference indicators: male waist circumference> 100 cm, female waist circumference> 90 cm.
