What is flatulence?
Everybody has gas – burping or passing gas through the rectum is perfectly normal.
Most of the gas passed is odourless. The odour in gas comes from the sulphur produced by bacterial fermentation in the large intestine.
Gas can cause bloating and pain for some people. The amount of gas created and how sensitive the person is to the gas is what effects the level of discomfort.
