Which term best describes an increased production of gas in the intestine?

The term that best describes an increased production of gas in the intestine is flatulence. Flatulence refers specifically to the presence of excess gas that leads to the expulsion of gas from the digestive tract through the rectum. This condition can result from various factors, including certain foods that are difficult to digest, fermentation processes in the gut, and stomach disturbances.

Borborygmus, on the other hand, refers to the rumbling or gurgling noises made by the movement of fluid and gas in the intestines, which may be heard during digestive processes but does not specifically denote the presence of excess gas or the resulting actions, such as flatulence.

Constipation indicates a condition where there is difficulty in passing stools and is not related to the production of excess intestinal gas. Similarly, diarrhea involves the frequent passage of loose or watery stools and does not inherently imply an increase in gas production.

Therefore, flatulence is the most precise term for the situation described, as it explicitly encompasses the concept of excess gas in the intestines.
