Introduction: Iatrogenic or physician-induced hypervitaminosis D is a rare cause of persistent vomiting. To the best of our knowledge, this is the first case report on iatrogenic hypervitaminosis D presenting with persistent vomiting in Pakistan.
Case report: We report a rare case of continual vomiting for 15 days in a 48-year-old woman of Pakistani descent. She was a known case of diabetes mellitus for 8 years, which was well controlled at the time of presentation.
Conclusions: The correct diagnosis of our patient was based on clinical suspicion, appropriate lab tests, and deliberation of the differential diagnosis. It is important to consider hypervitaminosis D as a cause of persistent vomiting if no other obvious is apparent.
