The chronic disorder most often affects the small intestine, but can also occur in the large intestine (colon). The acute disorder usually affects the large intestine.</p><p>The condition may start suddenly or be a chronic or long-term problem. Sudden onset is called acute intestinal pseudo-obstruction and usually affects the small intestine and often other parts of the digestive tract. Chronic intestinal pseudo-obstruction usually affects the large intestine (colon.) It is most common in children and older people. The cause of the problem is often unknown. However, problems with the bowel's muscles or nerves may be a cause.</p><p>Risk factors include:</p><ul><li><a test="test" href="./000716.htm">Cerebral palsy</a> or other brain or nervous system disorders.</li><li>Chronic kidney, lung, or heart disease.</li><li>Staying in bed for long periods of time (bedridden).</li><li>Taking medicines that slow intestinal movements.
