Sulfur burps: what is it and how to prevent it

The human being burps or expels flatulence throughout the day. These are normal processes that do not usually indicate the presence of pathologies. However, the expelled gases can have bad odors and be very embarrassing. One of these foul gases is sulfur burps.

Belching and flatulence are caused by the accumulation of gases in the gastrointestinal tract. They are composed of hydrogen, oxygen, carbon dioxide and nitrogen, in most cases, although they can also contain small amounts of methane, which gives them a characteristic odor.

Gases are usually produced by various causes, from the action of bacteria on food to the ingestion of air during swallowing. Sulfur burps have slightly more specific causes, so they can be prevented by taking appropriate measures.
