I am guessing you mean what is the scientific logic behind why a person needs to fart?
Basically speaking, the noise you hear when a person farts, or passes wind, is literally what the latter suggests; the expulsion of gasses from the anal opening. The air which is expelled comes from a number of different places, however the most common are swallowing gas (or air) and from chemical reactions in the body.
Excessive flatulence is the medical term given to those who fart an unusual amount on a daily basis. This excessive amount is generally caused by one of a number of factors:
- Swallowing a large amount of air when eating
- Swallowing a large amount of air due to a nervous disposition
- Intestinal bacteria working incorrectly
- Consumption of high levels of carbohydrates and certain foods
If excessive flatulence becomes an issue then considering these factors should help address the problem. If these changes make no difference and it seems that the problem really is excessive then it may be worth visiting a doctor to rule out any underlying health issues.
Problem which can cause excessive flatulence include:
As with lactose intolerance, excessive flatulence is also a common symptom of IBS. Other symptoms include stomach cramping, rumbling and gurgling stomach, diarrhea and constipation.
Although IBS is not currently treatable, removing foods that seem to trigger it from the diet can ease it. It is also believed that exercise, stress relief methods and hypnotherapy can help.
