Increased bowel sounds can be a significant indicator of an obstruction during a bowel examination. When there is a blockage within the intestines, the body responds by attempting to push the contents through the obstruction, which can lead to heightened activity in the bowel. This heightened peristalsis results in increased bowel sounds, also known as hyperactive bowel sounds.
In the case of a severe obstruction, bowel sounds may later diminish, indicating that the bowel is becoming inactive as it struggles with the blockage, but initially, the increased activity is a key sign. It is important for practitioners to monitor these sounds during examinations, as they provide valuable insight into the functional status of the gastrointestinal tract in cases of suspected obstruction.
