In primary intestinal pseudo-obstruction, the small or large intestines lose their ability to contract and push food, stool, and air through the gastrointestinal tract.
The condition can occur suddenly (acute) or over time (chronic). It may occur at any age, but is most common in children and the elderly. Because the cause is unknown, it is also called idiopathic intestinal pseudo-obstruction (idiopathic means occurring without a known reason).
Call your health care provider if you have persistent abdominal pain or other symptoms of this disorder.
