What is paralytic ileus?

Paralytic ileus refers to a condition characterized by a temporary cessation of normal bowel motility, leading to bowel inactivity. This lack of peristalsis prevents the movement of intestinal contents, which can mimic the signs of obstruction despite the absence of a physical blockage. It often occurs after surgical procedures, especially those involving the abdomen, but can also be triggered by medications, electrolyte imbalances, or abdominal infections.

In contrast to conditions that involve excessive bowel movements or specific inflammation, paralytic ileus signifies a state where the intestines fail to function properly, not due to a mechanical obstruction, but due to a functional impairment. This distinct characteristic differentiates it from other gastrointestinal issues that may involve inflammation or tumors, where the motility of the bowel may still be present but impaired by other pathological factors.
