When it comes to farting, everyone must think it is an embarrassing thing, especially in public. No one wants to admit that he farted. In fact, this is a normal physiological phenomenon, but it's just ugly. There are many kinds of farts, some are silent, some are loud, some are tasteless and some are smelly. Everyone is different. If it is silent and smelly, it is ok.
According to experts' research, fart is composed of more than 400 kinds of gases, and the main components are nitrogen, hydrogen, oxygen and carbon dioxide. Because the ingredients are different, the smell and sound are naturally different. There are many reasons for farting, such as eating too much beans, taking hypoglycemic drugs, gastrointestinal diseases and so on. If the number of farts suddenly increases, don't worry too much, but if this situation continues, it needs to be taken seriously.
People who never fart are usually due to poor digestion. Usually, this happens to some elderly people or people who have undergone abdominal surgery. If you fart too much or never fart, you can simply analyze it yourself first, and then carry out targeted inspections.
