After the recovery of the intestinal tract, appendicitis patients will experience gas, which is also known as farting, through the anus. In this case, the intestinal tract has gradually recovered, especially for post-operative patients. After the anal venting, the patient can be advised to eat and drink through the mouth, and initially eat a liquid diet. After eating, the patient’s abdominal symptoms and signs should be observed. If there is no increase in abdominal distension and pain, and if the patient can ventilate and defecate normally, the amount of food and dry food or semi-liquid diet can be gradually increased, and the patient should not overeat.
