Why do you always fart when you go home for dinner in the afternoon?

This is because when people eat food, due to the role of normal flora in the digestive tract, they will produce more gas. These gases move downward with the peristalsis of the intestine and are discharged from the anus. When it is discharged, due to the action of anal sphincter, noise sometimes occurs. Therefore, farting is a manifestation of the normal operation of the intestine. On the contrary, if you don't fart, or fart too much and stink, that's an abnormal phenomenon. There are roughly two reasons for farting often. One is that you often fart because you eat some gas-producing foods, such as sweet potatoes, onions, cabbage, beans and other soy products. In addition, you may suffer from irritable bowel syndrome, which may also cause abdominal pain, bloating and farting in clinic. In diet, it is recommended that you eat more in small quantities and don't overeat. Chew slowly when eating, avoid eating too much air together and avoid eating food that is easy to produce gas. Drinking a cup of yogurt every day helps to change the bacteria in the gastrointestinal tract.
