Question: Does the human gut produce methane?

In humans, methane-producing archaea (methano-gens) produce methane through anaerobic fermentation; the most common methanogen in the human gut is M. smithii, which is found in 70% of human subjects. Analysis of expiratory methane by lactulose breath testing can serve as an indirect measure of methane produc-tion.

Does human digestion produce methane?

Gas in the Intestines

The large intestine contains a number of different forms of bacteria that continue the digestive process, but this process creates byproducts—carbon dioxide, hydrogen, and sometimes methane.

What produces methane in the gut?

How can I reduce methane in my stomach?
