Carrot man: a case of excessive beta-carotene ingestion.

In this case report, the authors describe a 48-year-old male who complained to his primary care physician of abdominal discomfort and yellow/orange skin discoloration. Physical examination was normal except for some mild mid-abdominal discomfort (no observed skin color changes). An abdominal CT scan indicated a colon that was full of stool. Laboratory studies indicated elevated liver enzymes. Upon further questioning, the patient reported ingesting 6-7 pounds of carrots per week to facilitate his dieting effort. The patient was diagnosed with constipation, hypercarotinemia, and possible vitamin A toxicity. Following the cessation of excessive carrot ingestion, his liver enzymes normalized within 1 month.
