Nocturnal flatulence

Topic

Nocturnal flatulence refers to the release of intestinal gas (flatus) during sleep or late-night hours. It is a common physiological occurrence often caused by the accumulation of gas from evening meals, swallowing air, or underlying gastrointestinal conditions like irritable bowel syndrome (IBS). During sleep, the body's anal sphincter relaxes, which can lead to the involuntary passage of gas.
