Ileus (pronounced EE-lee-us) is a medical term for a temporary impairment of bowel movement or peristalsis, often following surgery or illness. It describes the inability of the intestines to contract normally, leading to bloating, abdominal discomfort, and lack of stool or gas passage. The term is used mainly in clinical settings and medical literature.
"The patient developed a postoperative ileus after abdominal surgery."
"X-ray confirmed a bowel ileus with distended loops of small intestine."
"Treatment focused on bowel rest and gradual reintroduction of nutrition to resolve the ileus."
"The surgeon monitored signs of ileus and adjusted fluids and electrolytes accordingly."
Ileus comes from the Latin ileus, meaning gut or bowels, reflecting its association with intestinal function. The term entered English medical usage in the 17th–18th centuries as anatomy and physiology advanced, adopting a Greek-rooted, clinically descriptive flavor. Early descriptions emphasized paralysis or diminished motility of the intestines following trauma or surgery. Over time, ileus broadened to cover various forms of non-mechanical bowel dysfunction, including adynamic ileus and paralytic ileus, with distinctions made between mechanical obstruction and functional paralysis. The word’s usage peaks in surgical, gastroenterology, and emergency medicine contexts, where accurate identification of motility impairment guides management. Modern literature distinguishes ileus from true obstruction by clinical signs, imaging, and progress with supportive care, while still using the term as a historical anchor for non-mechanical distension and pain patterns.

Ileus is pronounced as /ˈaɪ.ljuːz/ in many clinical contexts, with a two-syllable pattern: 'EYE-lyuz' or 'EYE-LOOZ' depending on speaker. The primary stress is on the first syllable. In some US practice, you may hear a lighter second syllable /-lus/ ending; in UK/AU, the /juː/ onset of the second syllable is more rounded. Visualize the sequence: /ˈaɪ/ (like eye) + /lj/ (lip-free light-J consonant blend) + /uːz/ (long ooz). Breath before the final consonant helps; avoid shortening the second vowel excessively, which can obscure the /juː/ sequence.
Common errors include flattening the second syllable to a simple /ɪs/ or /lɪəs/ instead of the /ljuːz/ sequence, and misplacing stress by overemphasizing the second syllable. Another frequent mispronunciation is saying /ˈaɪ-ləs/ without the /lj/ blend, making it sound like illness. To correct: ensure a light but present /l/ immediately after the /aɪ/ vowel, glide into /juː/ smoothly, and end with a /z/ rather than a /s/ sound when appropriate. Practicing the /lj/ cluster helps keep the classic medical pronunciation intact.
In US English, /ˈaɪ.ljuːz/ emphasizes a clear /lj/ blend and a long /uː/ before the final /z/. UK/AU accents typically retain the /ljuː/ sequence closely, but vowel quality on /aɪ/ can be slightly shorter and the final /z/ may devoice to /s/ in some speakers, though formal contexts keep /z/. Overall, the first syllable bears primary stress, with the /l/ light but audible. Be mindful of rhoticity: ileus remains non-rhotic in most accents, so the r-coloring does not apply here.
The difficulty lies in the /lj/ consonant cluster after the diphthong /aɪ/, which requires precise tongue position: the tip of the tongue touches the alveolar ridge while the blade/light contact forms the /l/ before quickly transitioning into /j/ as in 'you.' The /uː/ diphthong at the end can be shortened in casual speech, risking ‘ilyooz’ vs. ‘ile-us’ distinctions. Also, the word carries medical specificity, so speakers may momentarily hesitate, affecting rhythm and clarity. Practicing the /ˈaɪ.ljuːz/ sequence helps stabilize articulation.
No letters are formally silent; each of the three segments carries audible sound: /ˈaɪ/ as a diphthong, /l/ as a clear consonant, and /juːz/ where the /j/ blends with the /uː/ before the final /z/. However, in fast clinical speech the second syllable may appear slightly compressed, sounding like /ˈaɪljuz/ with a softer realization of the /juː/ onset. Focus on maintaining the /lj/ link and finishing with the voiced /z/ to preserve the standard form.
