Holding in Gas Could Make It Come Out Your Mouth Warns Expert

By

There's a few mixed opinions when it comes to gas. Many moms will tell you to hold it in until you get to a bathroom, while others will give you the old-age wisdom of "better out than in." But according to a dietetics and nutrition expert, you should probably just let it go. Why? If you don't, the fart could come out of your mouth instead. 

University of Newcastle's Professor Clare Collins says that holding in trapped wind may cause abdominal distension, "with some gas reabsorbed into the circulation and exhaled in your breath." Writing for The Conversation, Collins explained why holding it in is futile. 

"Holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable fart." 

Not only that, but holding in a fart could cause a condition called diverticulitis, which leads to small pouches developing in the gut lining and becoming inflamed.
