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.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.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.
