OSTEOMALACIA IN STAGNANT LOOP SYNDROME

Abstract

Osteomalacia in a 80 yr old woman with malabsorption due to the stagnant loop syndrome is reported. The osteomalacia was associated with bacterial overgrowth in the small intestine and increased bile salt deconjugation. Although the mechanism of osteomalacia in the stagnant loop syndrome remains uncertain, abnormal flora may reduce the absorption of vitamin D by deconjugation of bile salts in the lumen of the small intestine.
