First, how is flatulence formed?
When there is inflammation, reflux or tumor in the stomach and duodenum, the emptying of the stomach will be delayed, and food will constantly exert pressure on the stomach wall. At the same time, food produces a lot of gas after excessive fermentation in the stomach, which further increases the pressure in the stomach, so there will be a feeling of fullness and oppression in the upper abdomen, which is flatulence.
Second, what is the composition of flatulence?
The gases that cause flatulence are mostly waste gas, mainly nitrogen, oxygen, carbon dioxide, hydrogen and methane, which are usually tasteless, and a few rare gases such as hydrogen sulfide and ammonia have a bad smell. Among them, carbon dioxide, hydrogen, methane and hydrogen sulfide are all produced when food residues are decomposed by bacteria in the large intestine. These residues are mainly carbohydrates, plant fibers and a small amount of amino acids and fatty acids that cannot be digested and absorbed by the small intestine or are not digested and absorbed in time.
Generally speaking, most of the gas in the abdominal cavity is absorbed by the blood vessels in the intestinal wall and discharged from the body by the lungs. However, if the gastrointestinal function is not good, or there are some diseases, the blood circulation of the intestinal wall is likely to be hindered, which will affect the absorption of gas in the intestinal cavity and cause abdominal distension. The flatulence caused by inhaling excessive air will mostly lead to the weakening or disappearance of intestinal peristalsis.
So, what are the causes of flatulence?
There are basically the following four types: the absorption of gas by gastrointestinal tract is blocked; Gastrointestinal gas discharge disorder; Inhale a lot of air when eating because of bad speech or eating habits; The chyme in ascending colon stays too long and ferments.
For these four reasons, which diseases can lead to flatulence?
