Many people consult online whether they can rest on their laurels after weight loss surgery and will not gain weight again. In fact, no, weight loss surgery does have the advantages of high weight loss efficiency and low rate of regaining weight, but if the living and eating habits are unhealthy, there is still a chance of regaining weight, but the rate of regaining weight is very low, only 5% -10%. The principle of weight loss surgery is to modify the structure of the gastrointestinal tract to achieve the purpose of restricting diet and absorption, and at the same time use the time of physical recovery to lose a lot of excess weight. And after weight loss surgery, in addition to advising our patients to go through a diet of clear liquids, liquids, semi-liquids and then normal food during the recovery period, our health management department will also develop recipes that are suitable for each individual patient to ensure that the patient is able to obtain adequate nutrition. This is well explained in two common surgical diagrams. As we can see from this diagram, whether it is sleeve gastric surgery or gastric bypass surgery, they both reduce the volume of the patient’s stomach by a lot, which leads to the patient’s eating volume will not be as large as before. At that stage after the surgery, the patient’s gastrointestinal tract is still in the recovery stage, so the eating will be more restricted, but as the body recovers, it will be able to return to normal eating, only that the amount of a single meal will be This is also one of the reasons why the surgery prevents regaining weight. Reducing the amount of food in a single sitting does not mean that the total amount of food eaten will necessarily be reduced. If the patient can’t change the problem of liking to eat, and when the stomach digests a little bit, he starts to eat, which will eventually lead to overeating, and the phenomenon of regaining weight will thus occur. Therefore, although weight loss surgery can help patients control eating, but in the end it is still necessary to rely on patients to develop healthy eating habits. In addition to diet, exercise is also one of the most important factors affecting the results of surgery. As with most surgeries, proper exercise is very helpful for recovery after surgery. Proper exercise after weight loss surgery can not only strengthen the surgical weight loss and recovery effect, but also make the skin become tighter and prevent muscle atrophy, as well as an important measure to prevent regaining weight after surgery. One of the causes of simple obesity is eating a lot, and the other is moving less. Exercise can increase the consumption of energy, if you do not exercise after weight loss surgery, excess energy will also be stored in the body, and over time, naturally become fat. So even if you have had weight loss surgery, you still need to do a moderate amount of exercise to prevent regaining weight.
