What is the term for gas expelled from the digestive system?

The term for gas expelled from the digestive system is flatulence. Flatulence refers specifically to the accumulation of gas in the gastrointestinal tract that is eventually released through the rectum. This process is a normal physiological function and can occur as a result of various factors, including the digestion of certain foods, swallowing air while eating or drinking, and the activity of bacteria in the intestines that break down food.

Indigestion refers to discomfort in the digestive system, particularly after eating, and does not specifically denote gas expulsion. Borborygmi refers to the rumbling or gurgling sounds produced by the movement of gas and fluids in the intestines, which is related but not synonymous with the act of expelling gas. Constipation is a condition characterized by infrequent bowel movements or difficulty passing stools and is unrelated to the process of gas release from the digestive tract.
