Flatulence
Flatulence is the expulsion of gas from the intestines via the anus, commonly referred to as farting. "Flatus" is the medical word for gas generated in the stomach or bowels. A proportion of intestinal gas may be swallowed environmental air; hence, flatus is not entirely generated in the stomach or bowels. The scientific study of this area of medicine is termed flatology.
Passing gas is a normal bodily process. Flatus is brought to the rectum and pressurized by muscles in the intestines. It is normal to pass flatus ("to fart"), though volume and frequency vary greatly among individuals. It is also normal for intestinal gas to have a feculent or unpleasant odor, which may be intense. The noise commonly associated with flatulence is produced by the anus and buttocks, which act together in a manner similar to that of an embouchure. Both the sound and odor are sources of embarrassment, annoyance or amusement (flatulence humor). Many societies have a taboo about flatus. Thus, many people either let their flatus out quietly or even hold it completely. However, holding flatus inside the bowels for long periods is not healthy.
There are several general symptoms related to intestinal gas: pain, bloating and abdominal distension, excessive flatus volume, excessive flatus odor, and gas incontinence. Furthermore, eructation (colloquially known as "burping") is sometimes included under the topic of flatulence. When excessive or malodorous, flatus can be a sign of a health disorder, such as irritable bowel syndrome, celiac disease or lactose intolerance.
Non-medical definitions of the term include "the uncomfortable condition of having gas in the stomach and bowels", or "a state of excessive gas in the alimentary canal". These definitions highlight that many people consider "bloating", abdominal distension or increased volume of intestinal gas, to be synonymous with the term flatulence (although this is technically inaccurate).
Colloquially, flatulence may be referred to as "farting", "trumping", "breaking wind", "blowing off", "pumping", "pooting", "passing gas", "backfiring", "tooting", "beefing", or simply (in American English) "gas" or (British English) "wind". According to the Oxford English Dictionary, "wind" has been used for over 1100 years, "fart" for over 900 years, "trump" for 700 years, "break wind" for 500 years, and none of the others more than 200 years. Derived terms include vaginal flatulence, otherwise known as a queef. In rhyming slang, blowing a raspberry (at someone) means imitating with the mouth the sound of a fart, in real or feigned derision.
Generally speaking, there are four different types of complaints that relate to intestinal gas, which may present individually or in combination.
Patients may complain of bloating as abdominal distension, discomfort and pain from "trapped wind". In the past, functional bowel disorders such as irritable bowel syndrome that produced symptoms of bloating were attributed to increased production of intestinal gas.
However, three significant pieces of evidence refute this theory. First, in normal subjects, even very high rates of gas infusion into the small intestine (30 mL/min) is tolerated without complaints of pain or bloating and harmlessly passed as flatus per rectum. Secondly, studies aiming to quantify the total volume of gas produced by patients with irritable bowel syndrome (some including gas emitted from the mouth by eructation) have consistently failed to demonstrate increased volumes compared to healthy subjects. The proportion of hydrogen produced may be increased in some patients with irritable bowel syndrome, but this does not affect the total volume. Thirdly, the volume of flatus produced by patients with irritable bowel syndrome who have pain and abdominal distension would be tolerated in normal subjects without any complaints of pain.
