After appendicitis surgery, you usually need to fast for about 1~2 days, and you usually need to wait for anal defecation before you can eat. Currently appendicitis surgery, mainly includes traditional open surgery and laparoscopic surgery. Regardless of the type of appendicitis surgery, the use of anesthetic drugs will cause a certain inhibitory effect on the function of the gastrointestinal tract. Eating when gastrointestinal function is not restored may cause vomiting, choking and coughing, and choking when food mistakenly enters the trachea. After food enters the gastrointestinal tract, indigestion can be triggered due to weakened gastrointestinal function. Intestinal peristalsis is weakened or intestinal paralysis, and food residues may trigger intestinal obstruction. Generally fasting for 1~2 days, after the anesthetic effect completely disappears, gastrointestinal function is restored, and anal defecation, you can start to try to eat. Begin to transition to a liquid diet to a semi-liquid diet and then to a normal diet. After appendicitis surgery, it is recommended to follow the guidance of professional doctors and choose the eating time reasonably.
