Sulfur Burps

What are Sulfur Burps?

Sulfur Burps refers to when air and gases of the digestive system (normally colorless and odorless) are emitted through the mouth. If gases burped from the digestive system have a strong smell of sulfur or rotten eggs, something has gone wrong in your alimentary canal.

The smell is caused by a gas called hydrogen sulphide usually contained in sulfur proteins found in some foods and is released when they are broken down by sulfur reducing microbes in the stomach or small intestine. 1,2

  • An empty colon can also cause sulfur burps. An empty colon is typically caused by irritable bowel syndrome. Gall bladder problems may also cause sulfur burps.
  • Sulfur burps can be caused by an underlying health condition that prevents food from being completely digested thereby allowing sulfur reducing bacteria to produce hydrogen sulphide. Such diseases include:hernias, acid reflux, stress, celiac disease, pancreatitis, irritable bowel syndrome, Crohn’s disease and gastroesophageal reflux disease.


Except for the characteristic rotten egg smell, sulfur burps are usually accompanied by the following symptoms:

  • Diarrhea

  • Performing a stool test for ova and parasites may reveal the presence of Giardia lamblia, a single celled parasite usually present in water bodies that except for sulfur burps also causes abdominal bloating and diarrhea (or loose stool with mucus).
  • Small intestinal bacteria overgrowth (SIBO) is determined to be the cause of sulfur burps if the patient also suffers flatulence, bloating, diarrhea, lactose intolerance pr fructose malabsorption.
  • A colonoscopy and upper GI endoscopy can be performed to rule out abnormalities in that part of the alimentary canal that cause diseases like Crohn’s disease.
  • Tests for acid reflux and a check of GI scopes may be recommended by the doctor.
  • Sulfur burps caused by food rich in proteins can be distinguished from those with other causes because the stomach takes a comparatively longer time for processing and releasing the high protein meal. This causes acidity, makes the stomach feel bloated and stops as soon as the protein ingested is exhausted.
  • If sulfur burps begin on the heels of new medication, then consult your doctor or check the list of ingredients on the medicine for sulfur content.


  • Helicobacter pylori are a common cause of sulfur burps and doctors usually treat it with prescription of antibiotics taken over a course of seven to ten days.

  • Bismuth subsalicylate (Pepto Bismol) is a strong anti diarrheal drug which reduces sulfur burps and gas. It is sometimes prescribed to people suffering acute sulfur burps to bind hydrogen sulphide gas and expel it from the gastrointestinal tract. Pepto Bismol colors the tongue and stool black and should not be administered to children or longer than 3 weeks for adults.
  • Alka Seltzer is an anti-acid which neutralizes the acidity in the gastrointestinal tract and reduces formation of hydrogen sulphide gas.


  • Take plenty of water at a variety of intervals.
