"What Happens When You Hold in a Fart? Clare Collins, a professor of nutrition and dietetics at the University of Newcastle, explains that holding in a fart can cause intestinal gas to build up, leading to abdominal distension.

Some of this gas may be reabsorbed into the bloodstream and exhaled through your breath. If held in too long, the gas will eventually escape as an uncontrollable fart.

Research is unclear on whether this increases the risk of conditions like diverticulitis or has no significant impact. Studies also show that a high-fiber diet, like one including baked beans and psyllium, leads to fewer but larger farts.

For digestive health, the best approach is simple: when you feel the need to pass gas, find a private spot and let it go. Holding it in does more harm than good"
