Flatulence after appendicitis surgery is mostly caused by the fact that intestinal peristalsis has not yet recovered, and it usually disappears in a few days after the operation and will not be accompanied for life. In appendicitis surgery, due to the need for anesthesia during the operation, the peristalsis of the intestines is weakened after anesthesia; and the operation is an injurious operation, which is a stressful stimulus to the organism; furthermore, the need to separate and rattle the intestines during the operation may make the peristalsis of the intestines decrease, and all of these reasons can cause abdominal distension after the operation. Generally speaking, in a few days after the operation, the peristalsis of the intestines will gradually recover and the bloating will slowly improve. Patients need to pay attention to early bed activity, which can promote the recovery of intestinal motility. If the bloating is obvious, you can use metoclopramide, domperidone and other drugs as appropriate. If there is physical discomfort, please consult a doctor in time.
