Excess Vitamin D May Lead To Kidney Failure: A new study published in the Canadian Medical Association Journal has revealed that unfettered use of vitamin D may lead to kidney failure.
In a rare case, a 54-year-old man, after returning from a trip to Southeast Asia where he spent much of his holiday sunbathing, was diagnosed with kidney damage after he took high doses of vitamin D for years.
After referral to a kidney specialist and further testing, it was discovered that the man had been prescribed high doses of vitamin D by a naturopath, who recommended a dose of 8 drops every day, according to a study published in the Canadian Medical Association Journal.
“Although vitamin D toxicity is rare owing to a large therapeutic range, its widespread availability in various over-the-counter formulations may pose a substantial risk to uninformed patients,” said Bourne Auguste from the University of Toronto.
Clinicians must be aware of the risks of vitamin D use to limit complications related to hypercalcemia.
Calcium levels may get worse before getting better in patients even after cessation of supplements, as vitamin D is fat soluble.
“Our experience informs us that patients and clinicians should be better informed about the risks regarding the unfettered use of vitamin D,” suggested the researchers.
