Why do people fart? Farting is just a physiological activity that expels dirty gases from the intestinal cavity through gastrointestinal motility. It is a normal physiological phenomenon.
There are three sources of dirty gas:
First, the air swallowed into the stomach when eating or talking;
Second, the gas diffused from the blood into the intestinal cavity ;
Third, some foods contain gas-producing amino acids (such as fats, sugars, and amino acids) that are not easily digested and are decomposed by bacteria in the colon to produce gas.
These gases are discharged from the anus after sufficient fermentation in the intestinal cavity, which is what we commonly call farts.
Under normal circumstances, 100 to 150 ml of gas is often maintained in the intestinal cavity, and the total gas production of the human body is 500 to 1000 ml per day. Adults fart 5 to 20 times a day, and sometimes there is gas in the anus and they are not aware of it. If a person does not fart, or if he farts all day long, it may indicate that there is something wrong with his body.
There are many reasons for excessive farts, such as excessive intake of starch and protein foods that are not easy to digest, or stomach diseases such as indigestion, gastritis, peptic ulcer, and liver, gallbladder, and pancreatic diseases. , leading to reduced secretion of digestive enzymes and insufficient digestion after food intake. Functional indigestion is related to gastrointestinal peristalsis dysfunction, and diseases such as intestinal inflammation and cancer can cause organic indigestion, which can cause excessive farts. .
On the other hand, eating foods that are prone to gas production, such as radish, sweet potatoes, potatoes, yams, taro, soy products, onions, garlic, oatmeal, etc., contain a large proportion of gas that the body cannot absorb. Polysaccharide compound components. When the sugars these bacteria love enter the intestines, the bacteria go to work and produce a lot of gas.
The same principle applies to less farting. Some people think that they are proud of never farting or rarely farting, but this is not the case. Farts are exhaust gases produced by our human body and contain some toxic and harmful substances. Holding in the "waste gas" is not good for our bodies.
Suppressed farts will accumulate in the large intestine, be reabsorbed by the intestinal mucosa, and flow with the blood. Long-term this will cause chest tightness, abdominal distension and other symptoms, affect the digestion and absorption function, and aggravate the detoxification of the liver. Burden on organs. In addition, frequent holding in farts can cause chronic poisoning of the body, causing symptoms such as listlessness, indigestion, dizziness, and a sallow complexion.
In addition, the reason why farts are annoying is that they smell very bad. This is caused by the decomposition of food in the intestines. We can roughly judge the health of the human body through the smell of farts:
(1) Gastrointestinal bleeding and intestinal cancer - fishy smell
Fishy farts may indicate gastrointestinal bleeding. Blood accumulated in the gastrointestinal tract is decomposed by bacterial fermentation. Sometimes the feces excreted will look like Asphalt. In addition, when there is a malignant tumor in the intestines, the farts produced will also have a fishy smell due to the erosion, peeling, and bleeding of the cancer tissue, coupled with the decomposition and fermentation of bacteria. If your farts suddenly have a particularly fishy smell that lasts for more than 2 weeks, you need to be highly vigilant. It may indicate intestinal cancer, intestinal erosion, intestinal necrosis, etc. It is best to go to the hospital to have your stool checked quickly.
(2) Enteritis - extremely smelly farts
If your farts suddenly smell extremely smelly, but you have not eaten garlic, onions, leeks and other pungent smelling foods recently , and you have not consumed too much meat, you should be careful, because this phenomenon may be caused by some intestinal inflammation or gastrointestinal dysfunction.
(3) Dietary problems - rotten egg farts
Generally, if you eat greasy food or eat more meat, you are more likely to have rotten egg farts. This is because intestinal fermentation breaks down proteins and fats to produce indole and hydrogen sulfide, which not only have a foul smell, but are also toxic. These gases can corrode the intestinal wall, cause the intestinal barrier function to decrease, increase permeability, and allow toxic substances in the intestine to enter the blood, thus endangering human health.
Farting is indecent, but at certain times, it is worth a thousand dollars. If a patient who has undergone abdominal surgery can fart within 48 hours after the operation, the patient will feel comfortable and his family will feel at ease. , doctor is relieved. Because anal exhaust indicates to a large extent that the gastrointestinal peristalsis function has been restored, the patient can safely resume his diet gradually.
Therefore, farting too much or too little are signals sent by the body that require attention. So, how to regulate the behavior of farting?
(1) For people who often fart, it is recommended to eat small and frequent meals, avoid overeating, and chew slowly when eating to avoid Eat too much air together.
(2) Reduce the intake of starchy foods and increase foods rich in plant fiber such as vegetables. Avoid eating cold and raw foods, foods and drinks that produce a lot of gas, and avoid catching cold, which will help improve gastrointestinal function.
(3) Massaging the belly can promote gastrointestinal motility, reduce gastrointestinal burden, and help empty gas in the gastrointestinal cavity. For example, before going to bed, rub your hands together to warm them, then cover them around the navel and massage them alternately clockwise and counterclockwise. This is very helpful for the gastrointestinal tract and is suitable for people with food stagnation or gastrointestinal discomfort.
(4) Insisting on physical exercise can help promote the absorption of gastrointestinal nutrients and reduce the frequency of farting. Many people have symptoms of flatulence and constant farting due to lack of exercise and low gastrointestinal digestion and absorption efficiency.
If you still fart all the time after adjusting your eating habits, and are accompanied by increasingly aggravating symptoms such as diarrhea, constipation, and unformed stools, you need to go to the hospital in time and undergo a colonoscopy to rule out intestinal organic matter. Sexual disease.
