How long it takes to eat after appendicitis surgery is related to the patient’s age, physical quality, surgical method and other factors, and cannot be generalized. If the patient chooses laparoscopic appendectomy, and the patient is young, and the symptoms of infection are mild, the recovery time of gastrointestinal function after surgery will be relatively short, and the patient can have anal venting after 1-2 days, and the gastrointestinal function starts to recover gradually, then a small amount of liquid food, such as water, rice soup, etc., can be eaten, and then gradually resume normal diet. In the case of elderly patients, patients who choose traditional open surgery, and patients with septic perforation and diffuse peritonitis, the recovery of gastrointestinal function is usually slower, with 3-5 days to exhaust, and after exhausting, they can gradually eat. However, it is necessary to follow the doctor’s requirements, not too early or too much, but should be gradually transitioned from less to more, from thin to thick, in order to reduce the pressure of the intestine in the abdominal cavity, reduce abdominal distension, and facilitate the patient’s recovery. In addition, patients should be encouraged to move to the floor as early as possible according to their physical condition, which is conducive to promoting the recovery of intestinal function.
