After months of nausea and vomiting, a middle-aged man in the United Kingdom finally learned the toxic cause of his health problems: too much vitamin D. His doctors found that an overzealous supplement regimen was to blame.
The patient lost 28 pounds (12.7 kilograms) in three months and complained to his general practitioner of persistent abdominal pain, dry mouth, diarrhea and vomiting, according to a case study published July 6 in the British Medical Journal. At the hospital, doctors learned that the man’s symptoms had started about one month after he began an intense vitamin regimen suggested by a private nutritionist.
