My husband age is 33 he use to fart frequently , can u tell how should control fart?

Lots of reasons: The gas associated with flatulence can among other reasons originate from ingested air, fermentation of ingested food, or reflect gut dysfunction (dysmotility or inflammation). His doctor will ask if he is losing weight, has particular food intolerances, has had recent exposures/travel or taken antibiotics, uses probiotics, has problems with thyroid, diabetes, irritable bowel, has bleeding, more.
