what causes sulfur burps

Sulfur burps, which have a foul, rotten egg smell, are caused by the presence of hydrogen sulfide gas in the digestive system. This gas is a byproduct of digestion or can result from an underlying gastrointestinal issue. Specific causes of sulfur burps include the breakdown of certain foods, such as proteins, cruciferous vegetables, and pungent vegetables, as well as drinks like coffee and beer. Infections in the digestive system caused by H. pylori bacteria and Giardia parasites can also lead to sulfur burps. Other factors such as stress, reflux, and certain medications can contribute to this condition. In most cases, sulfur burps are harmless, but excessive or foul- smelling burps may be a sign of an underlying gastrointestinal condition that may need medical attention
