Sulfur burps are burps that smell like rotten eggs, caused by the presence of hydrogen sulfide (Hâ‚‚S) gas in your digestive tract. While regular burps are just excess air being released from the stomach, sulfur burps are different; they signal a chemical reaction inside your gut, often due to digestion issues or bacterial activity. Before reaching for prescription meds, it is a good idea to explore safe, natural home remedies that can help eliminate sulfur burps and promote better digestive health. Here are the top natural fixes you should definitely try.
