Patients who do not go to a large number but often fart are considered to have functional colon disease and constipation, which are directly related to the peristaltic dysfunction of the intestine and the dysbiosis of intestinal flora. If the patient has a bowel movement, but cannot pass stool, it is likely that the stool is relatively dry and embedded in the colon and anus. In terms of diet, patients should be encouraged to drink more water, eat more vegetables and fruits, eat less spicy, fried and other stimulating foods, and not drink alcohol.
