What is the term for an audible abdominal sound produced by hyperactive intestinal peristalsis?

The term "borborygmus" refers to the audible sounds made by the movement of gas and fluid in the intestines, particularly when there is hyperactive peristalsis. This phenomenon occurs when the intestines are unusually active, often leading to a rumbling or gurgling noise that can be easily heard. Such sounds are typically associated with digestive processes and can indicate various gastrointestinal conditions or simply signify hunger when the stomach is empty.

Understanding the nature of these sounds is crucial for healthcare professionals as they can provide insights into a patient's digestive health. For instance, excessive borborygmi can suggest conditions like diarrhea or other disorders affecting intestinal motility. This sound is often tested in clinical assessments and helps in diagnosing potential underlying issues.

The other terms listed refer to different gastrointestinal processes: eructation pertains to the expulsion of gas from the stomach through the mouth, melena refers to dark, sticky feces indicating upper gastrointestinal bleeding, and achalasia is a disorder affecting the esophagus that impairs swallowing. Each of these terms describes distinct physiological phenomena unrelated to the sounds produced by intestinal movement.
