Farting 20 to 30 times a day is not normal. Farting is a manifestation of normal peristalsis of the intestinal tract. Not farting or farting a lot and smelling bad is an abnormal phenomenon. If you fart a lot but don’t smell bad, you may have eaten gas-producing foods such as potatoes and sweet potatoes, gastritis, gastrointestinal dysfunction and a cold abdomen. If you fart a lot and it smells bad, it may be due to indigestion. Normal people need to expel about 500 milliliters of gas every day, and the number of farts is between 10 and 15 times. Farting is a normal physiological need. Farts are caused by the fermentation of undecomposed food in the intestines and stomach under the action of Escherichia coli bacteria to produce gas and the swallowing of air when chewing. It is recommended to eat small and frequent meals, chew slowly when eating, eat a balanced diet and consume less gas-producing food. If you find yourself farting abnormally more often, you should seek medical attention to clarify the cause so as not to delay your condition.
