Bismuth Toxicity Presenting as Declining Mobility and Falls

David B. Hogan, Cathy Harbidge, Amy Duncan

Abstract


A 77-year old woman presented with a history of falls. Known health problems included biopsy-proven collagenous colitis treated with bismuth subsalicylate. On examination, in addition to impaired balance and gait, she was found to have tremors and cognitive deficits. Investigations revealed a markedly elevated urinary bismuth level. Withdrawal of bismuth subsalicylate led to marked cognitive and physical improvement.
