What Does Sulphurous Flatulence Indicate?

Sulphurous flatulence may indicate a variety of gastrointestinal problems. There are several things you can do to find out what causes these symptoms and how to treat them.

Poor Digestion

Probably the majority of people have experienced sulphurous gas and/or belching (characterized by its rotten egg smell) at some time or another. It often indicates something as simple as a poorly digested meal.

Too Much Protein

If you find that you have these symptoms for an extended period of time, check to see if you are eating large portions of protein at meals. If so, you should reduce your protein intake to smaller amounts.


If this proves unhelpful, you may want to try eliminating gluten from your diet. The proteins in some grains are difficult to digest and can sometimes create sulphur-smelling gas.

Sulphurous gas and belching may also indicate problems in the intestines, such as ulcers or parasites. Your doctor can provide tests to see if either of these is the case.

Serious Health Concerns

Digestive problems can occasionally indicate Crohn’s disease and other more serious diseases. Consult your physician if your symptoms do not improve.
