Knowra Flatulence Flatulence Flatulence is the passage of gas from the digestive tract through the anus. The gas forms mainly from swallowed air and microbial fermentation in the intestines.
Intestinal gas : Gas present in the stomach and intestines, originating from swallowed air and digestive processes. Flatulence occurs when some intestinal gas travels out through the anus.
Digestion : The mechanical and chemical breakdown of food into substances the body can absorb. Incomplete digestion of some carbohydrates leaves material for intestinal microbes to ferment.
Low-FODMAP diet : A dietary approach that temporarily limits fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. Reducing selected fermentable carbohydrates can lessen gas symptoms in some people with irritable bowel syndrome.
Flatulence humor : Comedy that uses intestinal gas, its sounds, or its odors as material. The bodily sound and odor of flatulence have made it a recurring subject of jokes.
Gut microbiota : The community of microorganisms living in the digestive tract. Microbes ferment undigested carbohydrates and generate much of the gas released as flatulence.
Carbohydrate : A class of sugars, starches, and fibers that provides energy and structural material. Some carbohydrates reach the colon undigested and become substrates for gas-producing microbes.
Lactose intolerance : Digestive symptoms caused by insufficient lactase activity and incomplete lactose digestion. Unabsorbed lactose can be fermented by colonic microbes, increasing gas and bloating.
Etiquette : Conventional rules governing polite behavior in social settings. Social norms often treat audible or odorous flatulence as a breach of decorum.
Colonic fermentation : Microbial breakdown of carbohydrates in the colon, producing gases and short-chain fatty acids. This process produces hydrogen, carbon dioxide, and sometimes methane in intestinal gas.
Small intestine : The digestive organ where most nutrient absorption occurs. Carbohydrates that escape absorption here can contribute to colonic gas production.
