Burps that taste like eggs are caused by the presence of hydrogen sulfide gas (H2S) in your digestive system. This gas has a distinctive rotten egg smell and taste, and it is produced naturally in small amounts during digestion when bacteria break down foods containing sulfur. Foods rich in sulfur like eggs, meats, broccoli, garlic, onions, and dairy products can increase the production of this gas, leading to burps that taste or smell like eggs. In addition to diet, frequent sulfur burps can sometimes indicate underlying digestive conditions such as gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), bacterial infections like Helicobacter pylori, or slower digestion from medications. While occasional sulfur burps are usually harmless and related to diet, frequent or persistent eggy burps accompanied by other symptoms might require medical evaluation. To reduce eggy burps, it helps to identify and limit sulfur-rich foods, reduce stress, possibly adjust medications, and consult a healthcare provider if the problem continues or worsens.
