First of all, farting is a normal physiological phenomenon of human body. Fart is the gas that appears after the human body decomposes the food residue in the intestine through the intestinal flora. Normal people fart 10 times a day, and there is no abnormal stench. However, poor intestinal function, intestinal diseases, hepatobiliary diseases and other factors. It is easy to cause abdominal distension and discomfort, increase fart, and some have abnormal fishy smell or bloody smell.

Next, Dr. Ma answers the question of flatulence and fart.

1, dietary factors

First of all, normal fart is mainly related to eating habits, mainly eating some soy products, sweet potatoes, purple cabbage and other foods. Some of these foods contain carbohydrates that cannot be fully absorbed by the intestine, and these unabsorbable ingredients will ferment in the intestine to produce excessive gas. The average composition of this gas is 59% nitrogen, 2 1% hydrogen, 9% carbon dioxide and 7% methane.

2. Intestinal dysfunction

Long-term irregular diet, eating some cold and irritating foods, can easily lead to intestinal dysfunction, as well as some emotional effects, and various factors lead to weakened intestinal peristalsis. Therefore, food residues can easily lead to bacterial decomposition, producing a large amount of gas for a long time, and the gas produced by abnormal decomposition of bacteria in the intestine will have a bad smell.

3. Intestinal lesions

Intestinal diseases will not only lead to abnormal farting, but also lead to abnormal stool, mainly manifested in enteritis, intestinal polyps, intestinal mucosal ulcers, Crohn's disease, intestinal cancer and so on. These diseases will not only affect intestinal dysfunction, but also affect intestinal fluid secretion disorder. Some foreign bacterial infections can lead to intestinal flora imbalance, so it is easy to cause food residue decomposition and gas absorption.

Too much farting for a long time, dry stool needs to be checked in time, and some probiotics and laxatives should be taken orally. If it is an inflammatory infection, it needs timely anti-inflammatory treatment.
