Gas is swallowed through the esophagus when people eat and drink together, and finally runs down through the stomach and intestines to the anus, and is finally expelled through the anus to form farts. Studies have shown that the normal number of farts for each person is about 10-14 times a day, and there are two reasons for frequent farts: 1) frequent consumption of sweet potatoes, onions, potatoes and other soy products that produce gas; 2) unbalanced eating habits and frequent overeating that lead to swallowing large amounts of air. Normal farting can indicate the health of the intestines, stomach and digestive tract in the human body. If the number of farts is too many and the farts are too smelly, then you need to pay attention to whether there is a disease in the digestive tract, intestines and other parts of the body, and it is recommended to go to the hospital for consultation.
