Ileus may occur after abdominal or pelvic surgery. Certain drugs or diseases, such as Parkinson's, also may cause this condition.


Symptoms include abdominal cramps, nausea, vomiting, diarrhea, constipation, gas, and bloating.


Ileus is treated by passing a tube from the nose to the stomach or small intestine to suck out air and relieve abdominal swelling while waiting for bowel function to return.
