Many people should know that weight loss surgery is very effective in treating morbid obesity and type 2 diabetes, so there are many people who put their hopes on weight loss surgery to treat these two diseases and look around for information about the surgery. But what people may not know is that the most important thing they need after weight loss surgery is a health manager. A health manager who does health management actually plays a decisive role in the outcome of weight loss surgery as well as surgery. Weight loss surgery is inseparable from health management Weight loss surgery has a long history, almost seventy years. In the early days of its development, there was no such concept as health management. Usually, patients came for surgery to be examined in the hospital, assessed the risks of surgery, stayed in the hospital for a few days to recuperate after the surgery, and the doctor ordered some matters to be taken care of after discharge and that was the end. However, it was later discovered that it was difficult to guarantee the results of the surgery and that complications could occur. This is how the concept of health management came into the system of weight loss surgery. Health management is an experience summed up from actual cases little by little, and it has developed into a more mature system now. As of now, a mature health management team needs to be equipped with a variety of experts such as health managers, nutritionists, and psychological counselors. Their work also starts from the time the patient arrives at the hospital and continues. Throughout the entire surgery, the health management team works with the attending physician to communicate with the patient during the preparation phase of the surgery to understand the patient’s condition, living habits, and eating habits, which will serve as a basis for developing the patient’s post-operative recovery plan. They will also give psychological guidance to the patient so that the patient can maintain a good mood and, if necessary, arrange for the patient to recuperate so that the surgery can proceed smoothly. In the days following the surgery, they will provide nutritional solutions to ensure that the patient does not suffer from nutritional imbalance, provide psychological guidance to the patient, develop a recovery plan, and cooperate with the doctor to deal with emergencies to ensure that the patient can safely survive the most debilitating days after surgery. After the patient is discharged from the hospital, follow-up guidance from the health manager and nutritionist is also very important. At this time, the patient is still in the adaptation period. To prevent complications from surgery, they should pay attention to the patient’s diet, psychology, living habits and other aspects of the problem, give the corresponding stage of the diet plan, etc. If there is a situation, they should give a timely response plan, urge the patient to develop good living and eating habits, and solve the patient’s psychological problems caused by surgery. Almost after the three-month adaptation period, they maintain constant attention to the patients, giving them recipes and advice on all aspects. They also have to remind them to follow up on time in order to determine the actual condition of the patient. This is also the only way to achieve the desired results of the bariatric surgery. Health management occupies a very important place in bariatric surgery, and it is a very varied and complicated task. But only such a mature health management system can guarantee the effect of the surgery, otherwise even if the surgeon is good, the weight loss surgery will still be useless. And those who really understand bariatric surgery will definitely include this into the key inspection when evaluating the team doing the bariatric surgery.
