Abstract
We describe 3 patients with short bowel syndrome who had persistently elevated serum methylmalonic acid (MMA) levels while being treated for vitamin B12 deficiency. Following treatment for presumed small bowel bacterial overgrowth, MMA levels normalized. Among patients with short bowel syndrome, MMA levels may have limited specificity for vitamin B12 deficiency.
