FAQ
Frequently Asked Questions
Ileus is a specific type of bowel obstruction, often functional or paralytic, where the bowel muscle stops contracting. A mechanical obstruction (e.g., from a tumour) is also a bowel obstruction but not always specifically called an ileus.
No, it is a highly technical term. Using it in everyday conversation would be confusing and inappropriate.
It is pronounced /ˈɪliəs/ (ILL-ee-us), with stress on the first syllable.
The most common cause is postoperative ileus, which frequently occurs after abdominal surgery due to handling of the intestines and anaesthetic effects.
