Why do people fart? Farting is a normal physiological reaction.

We humans need to eat every day, and as long as we eat, we will have corresponding urination and defecation, and farts. These are all normal. Although farting is a very normal physiological phenomenon, the stench makes people frown. If you fart in public, you will fall into an embarrassing situation. Therefore, many people find farting very annoying. They want to know: Why do people fart?

Farting is actually a normal physiological reaction of human beings. Everyone will experience it. However, if you fart too often, it means that there may be a problem with your digestive system. At this time, you should pay attention. So, why do people fart? Now, let the experts introduce it.

The normal human digestive tract usually holds 120-150 ml of gas.

However, since gas is constantly produced and discharged, the total amount of gas passing through the digestive tract every day can sometimes reach three or four thousand milliliters. It can be seen that a person exhales a lot of gas every day.

So, where does so much gas come from? First of all, it is the air that enters our body through our nose or mouth when we breathe, eat and talk; the other is the gas produced by the fermentation and decomposition of the food we eat by bacteria in the digestive tract, especially some difficult to digest foods that produce more gas; then there is the gas carried in the blood, mainly carbon dioxide, which also diffuses into the intestinal cavity.

According to research, part of the gas in the human digestive tract is in the stomach, most of it is in the large intestine, and there is less gas in the small intestine because the small intestine has the function of absorbing gas.

Gas in the stomach comes mainly from swallowing food. The composition of the gas is similar to that of air. The large intestine is mainly composed of nitrogen and carbon dioxide, as well as small amounts of oxygen, hydrogen and methane, as well as ammonia, hydrogen sulfide, indole and skatole. Therefore, the gas in the large intestine has a bad smell. The gas in the large intestine is discharged from the anus as smelly farts.

The above is the expert’s analysis on why people fart. I hope it can help friends who are interested. Experts point out that farting is actually normal. On the contrary, if you don’t fart every day, it is very likely that there is a problem with your gastrointestinal tract. At this time, proper conditioning should be carried out to avoid adverse consequences caused by damage to gastrointestinal function.
