When it comes to farting, many people are helpless. After all, it is a very indecent behavior to be discovered when there are too many people. This behavior is extremely embarrassing. Someone would hold back the fart that was going to be released. Where did the fart that was held back go?
Generally speaking, under normal circumstances, people fart more than ten times a day, the total volume is about 500 ml. There are generally two sources of fart: one is the air swallowed when talking or eating; the other is the gas produced when the bacteria in our intestines break down food. People (including babies) have to eat every day, and part of the air will enter the stomach with the food between eating (including when babies drink milk powder because they need to be ventilated, some air will enter the stomach). The air that enters the stomach descends to the intestines, and the air that is swallowed generally has no smell. Some of the gases decomposed by bacteria have no peculiar smell, and some have a strong smell.
The composition of fart is more complicated. Tasteless fart contains oxygen, hydrogen, nitrogen, carbon dioxide, methane, etc.; fart that smells bad contains hydrogen sulfide, ammonia, skatole, volatile fatty acid and other substances. The smell of fart is different if the food you eat every day. Under normal circumstances, if you eat vegetarian food, such as rice, steamed buns, noodles, sweet potatoes and fruits, the fart will not smell too much; if you eat too much meat, soy products, and dairy products, the fart Your fart is easily cocky. If someone eats something too rich at the banquet, then he may release very stinky farts to affect people nearby.
In many serious or important occasions, if someone takes the farts back when there are too many people, don’t worry, they just return to the intestines. Of course, some people will doubt that the fart held back will not be released through hiccups? Please rest assured that the peristalsis of the intestines is from top to bottom. Besides, it is impossible for a small volume of gas to travel retrogradely through the curved six or seven-meter long intestines back into the stomach. These gases only temporarily return to the intestines to wait for the next discharge.
However, if you hold fart for a long time, a large amount of toxic gas will accumulate in the intestines, will re-enter the blood circulation, and slowly decompose during the circulation in the body. Of course, some harmful gases cannot be eliminated in time and will be repeatedly absorbed by the intestinal mucosa. At this time, bad conditions such as abdominal pain and chest tightness will appear.
Farting is a normal physiological behavior of the human body. In the eyes of doctors, a person’s low fart or high fart is an abnormal manifestation of the body. For your own intestinal health, you need to pay attention to the issue of farts.
