NCIt definition : A disorder affecting the small intestine. It is caused by the stasis of food and subsequent
overgrowth of bacteria in a portion of the small intestine that is unintentionally
bypassed as a complication of abdominal surgery or as a sequela of gastrointestinal
disorders which impede effective motility. Clinical signs include bloating, abdominal
pain, diarrhea and weight loss. If untreated, the clinical course progresses to malabsorption
of fats, vitamin B12 and calcium, the latter which predisposes to nephrolithiasis
and osteoporosis.;
