Farting is a normal physiological phenomenon of human beings. When people digest food, they will produce more gas because of the normal flora in the digestive tract. These gases move downward with the peristalsis of the intestine and are discharged from the anus. When it is discharged, due to the action of anal sphincter, noise sometimes occurs. Therefore, farting is a manifestation of the normal operation of the intestine. Therefore, Chinese medicine has the saying that "the stomach qi drops below the normal level". If you don't fart, you are sick.

Not only Chinese medicine has a positive explanation for farting, but also western medicine tells patients and their families to pay attention to postoperative exhaust after laparotomy. Western medicine explained that the patient's postoperative exhaust marks the recovery of normal physiological function.
