First case of vitamin D toxicity
Clips from the post
- A 67-year-old woman went to the hospital with a history of lethargy, memory impairment, confusion, loss of appetite, and loss of equilibrium for two-weeks duration.
- Her routine biochemistry showed elevated blood calcium at 14 mg/dl. This is dangerously high. *The doctors then checked her vitamin D level and it was also extremely high at 254 ng/ml.
- . . all of this woman’s lab tests including her liver tests, lipids, thyroid panel, and blood counts were completely normal. (other than Calcium)
- it took a full six months for her levels to come down to 66 ng/ml.
- If you notice any symptoms of calcium overload (extreme tiredness, bone and muscle pain, and increased thirst), cut back on how often you take it. You’ll soon be back to normal.
