After surgery, it is better to eat liquid food or semi-liquid food, including rice soup, thin rice, rib soup, fish soup, meat soup, noodle soup, etc., which can increase nutrition and replenish water. Because the patient’s body is weak and not fully recovered after the surgery, if the abdominal surgery is performed, the gastrointestinal function may not be fully recovered, and the patient may have paroxysmal abdominal pain and abdominal distension. It is generally recommended to eat liquid food or semi-liquid food, which is easier to digest and absorb in the intestinal tract. When the patient’s bowel movement is normal and the abdominal pain is relieved, the patient can generally resume normal diet, but also with soft and easily digestible food.
