What does impaction refer to in a medical setting?

Impaction in a medical context specifically refers to a situation where a hard mass of fecal material becomes lodged in the intestine, leading to a prolonged inability to pass stool. This condition can result in significant discomfort, pain, and potentially serious complications if not addressed. Impaction might arise due to various factors, such as a low-fiber diet, dehydration, or a lack of physical activity, contributing to the hardening of stool and its subsequent retention within the bowel. Understanding this correct definition is crucial in differentiating it from other gastrointestinal issues, such as swelling or blockages caused by foreign objects, which involve different mechanisms and treatments.
