A month later, he began to experience vomiting, nausea, abdominal pain, leg cramps, tinnitus, dry mouth, diarrhea and weight loss and was taken to the hospital for treatment.
Blood tests showed that the man’s calcium levels were too high, magnesium levels were slightly higher, and vitamin D levels were about seven times the normal amount.
The man was discharged after eight days of hospitalization. His examination two months after his discharge found that his calcium levels had returned to normal, but his vitamin D levels were still abnormally high.
