Squatting to fart in the restroom is usually required after a colonoscopy. Colonoscopy is one of the most direct and effective methods to check the intestines. During the process of colonoscopy, it is necessary to inflate the intestinal lumen continuously, which makes the intestinal lumen dilated and helps to observe the specific situation in the intestines more. After the end of colonoscopy, the gas in the intestines can be automatically discharged through the normal peristalsis of the intestines, which is a normal phenomenon, but usually there will be abdominal distension and other discomforts, and you can go to squatting toilets to fart. Patients who need to undergo colonoscopy should cooperate with the doctor’s operation process, if the symptoms of farting all the time after the colonoscopy are recommended to go to the hospital.
