Commonly known as farting, passing wind, or having gas, flatulence is a medical term for releasing gas from the digestive system through the anus. It occurs when gas collects inside the digestive system, and is a normal process.
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.
