What is an ileus?
A person with an ileus has a condition that slows, or prevents, the passage of material through the intestines. Unlike an intestinal obstruction, which completely blocks the passage of material through the intestine, an ileus usually resolves without treatment. Common causes of ileus include a medication side effect, anesthesia, abdominal surgery, and abdominal injury.

What are the symptoms of an ileus?
Symptoms of an ileus include cramping abdominal pain, abdominal bloating, anorexia, and constipation.

How does the doctor treat an ileus?
Treatment for an ileus depends on the underlying cause and may include a liquid diet, intravenous fluids, and a change in medication.
