Eating onion always fart may be due to the onion itself easy to produce gas, after eating onion stimulate the gastrointestinal mucous membrane and so on, belong to the normal physiological phenomenon.
1. Onion itself is a gas-producing food, which can increase gas in the gastrointestinal tract after consumption, which may cause farting, and may also be accompanied by abdominal distension.
2. Onion is a spicy and irritating food, which may stimulate the mucous membrane of the digestive tract and promote gastrointestinal peristalsis, causing farting all the time.
Generally speaking, after stopping eating onions, the phenomenon of farting will disappear, and if accompanied by abdominal distension, it can also be relieved, so there is no need to pay too much attention to it. However, note that for those who often have flatulence and farting (such as gastrointestinal dyspepsia patients), the consumption of onions will aggravate the abdominal distension and increase in farting, and therefore it is best for these people to eat onions sparingly.
