what causes flatus to smell like sulfur
With regards to sulfur burps, most of us understand it to mean rotten eggs. Hydrogen sulfide is the gas that is released from rotten eggs to give it the characteristic offensive odor, similar to stink bombs used in pranks and one of the components of flatus (âfartâ). While this offensive odor is not entirely unexpected with flatus, it is often a cause for concern when it is smelled in burps. Since belching expels gas from the upper digestive tract it is logical to assume that the source of the sulfur burps lies in this area.
