Frequency of flatus is proportional to the amount of gas in the colon

Is it a Myth or a Fact? Find out below

The frequency of flatus is variable and so is the amount of gas passed. Some people pass small amounts frequently. Others may pass large amounts of gas but fewer number of times. Frequently, the complaint of excess gas implies the foul odor with its associated social embarrassment and not so much as the amount. It is also possible that some people especially those with irritable bowel syndrome are more sensitive to the presence of gas. They sense more distress in response to the amounts of gas that are not bothersome to others.

Flatus

Flatulence is the expulsion through the rectum of a mixture of gases that are byproducts of the digestion process of mammals and other animals. The mixture of gases is known as flatus, (informally) fart, or simply gas, and is expelled from the rectum in a process colloquially referred to as "passing gas" or "farting". Flatus is brought to the rectum by the same peristaltic process which causes feces to descend from the large intestine. Depending upon the relative state of the anal sphincter (relaxed/tense) and the positions of the buttocks, this often results in an audible crackling or trumpeting sound, but gas can also be passed quietly. The noises commonly associated with flatulence are caused by the vibration of the anal sphincter, and occasionally by the closed buttocks.

The olfactory components of flatulence include skatole, indole, and sulfurous compounds. The non-odorous gases are mainly nitrogen (ingested), carbon dioxide (produced by aerobic microbes or ingested), and hydrogen (produced by some microbes and consumed by others), as well as lesser amounts of oxygen (ingested) and methane (produced by anaerobic microbes). Odors result from trace amounts of other components (often containing sulfur compounds).
