Flatulence is a medical state in which excess pressure buildup of stomach or intestinal gas occurs which can cause excessive bloating, discomfort, uneasiness and often times leads to increased burping or even passing of gas through rectum. The longer you hold it the smellier it gets. The normal production of gas in a human body is 1-3 pints per day and they pass it out approximately 14 times in a day which is considered healthier but if this number exceeds due to increased production of gas then that becomes a cause of concern and is known as a disease called Flatulence.
