When I just finished this operation, I usually suffered from gastrointestinal injury, nausea and vomiting. If the postoperative recovery is not good, it will also cause a series of digestive system diseases, such as gastritis and enteritis. And even stomach bleeding, which is a more serious situation.
At the same time, after gastrectomy, the capacity of the stomach will become smaller, and the food intake can not meet the nutrition needed by the body, which will cause indigestion and anemia for a long time.
Therefore, it is not recommended to control weight in this way to achieve the effect of losing weight. To lose weight, you need to control your food intake and exercise more.
