Vitamin D Toxicity

Vitamin D toxicity occurs when an excessive amount of this vitamin accumulates in the body, which can disrupt the balance of calcium in the blood and affect the functioning of various organs.

How it may show up: It is usually linked to a general feeling of being unwell, nausea, intense thirst, an increased need to urinate, and, in some cases, effects on the kidneys.

Why it happens: It is generally associated with prolonged intake of very high amounts of supplements, rather than with sun exposure or a regular diet.

Which specialist treats it? Clinical nutrition provides guidance on the appropriate intake of vitamins, and nephrology gets involved when the kidneys are affected. Before starting or continuing any supplement, the prudent thing is to have a professional assess each person's actual needs.
