Postoperative management is an important part of bariatric metabolic surgery. Numerous clinical cases have demonstrated that sound and reasonable postoperative management not only enhances the outcome of surgery, but also prevents surgical complications. Therefore, in recent years, not only has the procedure of bariatric metabolic surgery been progressing and innovating, but also the research on postoperative management has been improving and popularizing. Trauma recovery is a step that should not be taken lightly in all surgeries and requires the cooperation of the doctor and patient, which may lead to different degrees of complications if not handled properly. At present, weight loss metabolic surgery has basically been carried out in a laparoscopic way, so the abdominal surgery trauma is generally very small, only 3 to 4 wounds of about 0.5-1cm, under the care of the hospital can heal in a few days, basically will not have too much impact, patients need to pay attention to the recovery of the anastomosis above the gastrointestinal tract. Nowadays, the mainstream weight loss metabolic surgery is mainly to modify the gastrointestinal tract, such as the sleeve gastrectomy surgery is to remove most of the stomach in the direction of the greater curvature of the stomach, and then stitch up the remnant stomach. As most of the stomach is removed, the volume of the stomach becomes smaller and the stitches need time to heal, the diet needs to be adjusted from a clear liquid diet to a normal diet slowly, the specific transition time depends on the surgery and your recovery, and also avoid eating those foods that are stimulating. In addition, exercise and lifestyle habits will also have an impact on the recovery, and it is best to do so under the guidance of a doctor.
