In this episode, we review ileus, a functional inhibition of gastrointestinal motility without mechanical obstruction, most commonly seen after surgery. We break down the neurogenic and inflammatory phases that suppress peristalsis, along with key risk factors such as opioid use, intra-abdominal infection, and electrolyte imbalances. The discussion highlights how to distinguish ileus from small bowel obstruction using imaging, clinical findings, and time course. We also cover supportive management, prevention strategies including ERAS protocols, and practical clinical pearls to reduce complications and hospital length of stay.
