Gaseous substances in (or released from) the stomach or intestines in the digestive tract. Over 99% of the volume consists of nitrogen (N2), oxygen (O2), carbon dioxide (CO2), hydrogen (H2) and methane (CH4), that are byproducts of the digestive processes, result of swallowed air or diffusion from blood and bacterial fermentation.Odor is determined by over 3000 different compounds comprising less than 1% of the volume. Metabolites include volatile sulfur compounds, indole, skatole, ammonia, and short chain fatty acids.
Excess intestinal gas in the stomach or upper intestine usually results in excess burping or belching. Excess intestinal gas in the lower intestine may result in increased gas being expulsed through the rectum Excess gas remaining in either location can cause cramping or pain, often without an obvious pattern.
The list of euphemisms for gas passing is very large (300+ in English) and includes expressions such as passing wind, flatulence, flatus, fart, air, and toot.
