The reduction of the stomach can be accomplished through dietary control or, if necessary, surgical removal. 1. Eat less and eat more: The stomach is stretchy, and eating too much each time will increase the capacity of the stomach. If you eat less and more frequent meals, your stomach will gradually shrink in the long run. Eating less and more frequent meals has a better effect on the protection of gastric mucosa, which can neutralize the gastric acid, avoiding the gastric acid causing irritation to the gastric mucosa, abdominal pain and bloating, belching, acid reflux and other uncomfortable symptoms. 2. Surgical resection: Surgical resection is a relatively fast way to reduce the size of the stomach. Because the stomach is cut, the diet must be carried out in a gradual manner. However, it is necessary to know that surgery is risky after all, and it is not suitable for every patient, it is recommended to go to the regular hospital according to their own conditions and choose carefully.
