Burping or passing gas through the rectum is normal. Most of the intestinal gas is odorless. The sulfur made by bacteria in the small intestine is responsible for the odor. Occasionally, gas can cause bloating and abdominal discomfort.

Bloating, burping and flatulence are common causes of intestinal gas, and this  can often be managed by modifying the diet. Occasionally, these conditions are the manifestation of a serious gastrointestinal disease, especially if the symptoms are refractory. Click here for more information on intestinal gas.
