Excessive flatulence is generally caused by bacteria that live in the intestines. Another, less common, cause is the swallowing of excessive air. Intestinal bacteria produce different amounts of gas depending on what you eat. Sugars and polysaccharides tend to yield flatulence. If excessive flatulence is a problem, adjusting your diet can make a big difference.
Flatulence (Farting): Causes, Symptoms and Remedies. Flatulence, also known as farting or passing wind, is the passing of gas from the digestive system out of the back passage. Flatus is the medical word for gas generated in the intestinal tract. Medical literature describes flatulence as flatus expelled through the anus. Flatulence is commonly a source of laughter or embarrassment. Excessive flatulence can cause enormous discomfort and distress, mainly when there are other people around. A bout of flatulence can strike at the most undesirable moments - during a meeting, or even worse in a crowded elevator.
