|Gluten Sensitivity||1%||Ruled out|
|Helicobacter Pylori Infection||1%||Ruled out|

If you suffer from sulfur burps and gas you may have a problem in the gallbladder or small intestine.

When gallstones block the bile duct and prevent bile from helping to digest fatty foods, gas may be produced due to incomplete digestion.
Recurrent "rotten-egg" burps accompanied by diarrhea could be a sign of Giardia lamblia infection.
