Farting, or Flatulence is commonly used to describe the production of methane, in the gut and intestines. Methane is produced by methanogens (Methanobrevibacter smithii bacteria), which are an essential component in the guts microbial ecosystems. Gases in the gut are composed of various quantities of exogenous (outside) sources and endogenous (internal) sources. Exogenous gases are swallowed, when eating, or drinking, or because of increased swallowing, during times of excessive salivation (might occur when nauseated, or the result of GERD). The endogenous gases are produced, by incomplete digestion, or as a by-product of consuming certain types of food.
Anything that causes food to be incompletely sterilized, broken down and converted by the stomach may cause flatulence, or gas.. Endogenous gasses arise from bacterial fermentation of complex sugars and simple sugars. The microorganism Methanobrevibacter smithii plays an important role, in the efficient digestion of complex sugars, by consuming the end products, of bacterial fermentation. They remove excess hydrogen from the fermented nutrients that were properly broken down, sterilized and converted in the stomach. Methanobrevibacter smithii (M. smithii) is vitally important in the digestive process, and is responsible for removing excessive amount of methane, by absorbing hydrogen.
When the stomach can no longer completely breakdown, sterilized and convert the nutrients consumed, M. smithii bacteria can no longer maintain the proper balance, in the digestive process. M. smithii bacteria cannot adequately consume all of the end products of bacterial fermentation, resulting in excess methane development.
The excess generation of methane results in flatulence. More importantly, it causes impaired motility of nutrients through the digestive tract. The decrease motility is directly linked to the pathogenesis of constipation, IBS, as well as obesity and gastroparesis. Conversely, when pathogens are combined with the excess methane the body can experience, explosive diarrhea. Anything that prevents nutrients from being completely broken down, sterilized and converted will result in flatulence. The decrease in motility, caused by incomplete digestion, has a direct influence on the amount of calories absorbed and body fat. People that have excess methane production are more susceptible to excessive weight gain and obesity.
Incomplete digestion, or anything that prevents nutrients from being broken down, sterilized and converted, in the stomach causes malabsorption. Incomplete digestion will also cause excessive methane production, obesity, and vitamin and mineral deficiency. Hypochlorhydria and Achlorhydria cause incomplete breakdown, sterilization and conversion of the nutrients consumed. Both conditions can be the result of aging, antibiotics, proton pump inhibitors (PPIs) and a host of other chemical medications. They can also caused by various viruses and environmental toxins.
