Peristalsis is a wavelike, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/bones-muscles-joints.html/">muscular</a> contraction of the intestines. With an ileus, peristalsis slows down or stops somewhere in the intestines, causing waste products to stop moving and back up.</p> <p>An ileus is often a temporary side effect of abdominal surgery or spine surgery. It can also be caused by injuries or infections such as viral illness, chemical or electrolyte imbalances, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/about-genetics.html/">genetic</a> disorders, and certain medications. It can cause pain, vomiting, cramps, and constipation; if not treated, it can lead to complications.</p> <p>Treatment involves treating the cause of the ileus and allowing the intestines some time to rest. The doctor may recommend a blander, more easily digested diet. In more severe cases, hospitalization, no food by mouth, and intravenous (IV) fluids are required.</p> <h3>Keep in Mind</h3> <p>An ileus caused by surgery typically clears up in 2 to 3 days. Most other cases will get better in a few days as well. Surgery to treat paralytic ileus is extremely rare and is only used as a last resort.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
