💨The gut microbiota generates ~0.2L–1.5L of gas per day
💨>99%: hydrogen (H2), carbon dioxide (CO2), & methane (CH4)– *odorless*
💨foul smell of gas from <1%: sulfur–containing gases hydrogen sulfide (H2S), methanethiol (CH3SH), dimethyl sulfide [(CH3)2S] + volatile compounds
🦠bacteria in the colon ferment substrates that are not digested or absorbed in the upper GI tract (e.g. carbohydrates, proteins, fats)
🦠produce short-chain fatty acids, branched-chain fatty acids, ammonia, N-nitro compounds, phenolic and indolic compounds, and various gases
