If the fart is held in temporarily, the gas will remain in the intestines and be released the next time through the exhaust; if the fart is held in for a long period of time, a large amount of gas will build up in the intestines, and it will be circulated with the blood, and ultimately be discharged out of the body by breathing through the mouth and nose. If the fart is held in temporarily, the gas will remain in the intestines and will be released the next time through exhaust. However, if you hold in your farts for a long time, the gas will accumulate in the large intestine, be absorbed by the intestinal wall and enter the bloodstream, and with the blood circulation, it will reach the liver to be filtered, and finally reach the lungs, and be discharged out of the body through the exchange of gases in the lungs. Holding in farts will increase the burden on the liver, which is a detoxification organ, and holding in farts for a long period of time will weaken its detoxification function, and holding in farts for a long period of time will cause a large amount of gas to accumulate in the intestinal tract, leading to bloating, abdominal pain, and so on. Therefore, it is recommended not to hold in your farts for a long time, and to seek medical attention if you feel unwell.
