Germs create gasses: The odor of flatus is derived from the gas produced by the germs that live in your digestive tract. Methane is one common product. The character of the odor is influenced by your diet and the variety of gasses produced by separate bacteria.The germs live off what is not absorbed during digestion. Taking some probiotics may improve the germ balance & lessen the smell.
