Hypervitaminosis D
Information, Symptoms, Treatments and Resources
An excess of vitamin D causes abnormally high levels of calcium in the blood, which can eventually severely damage the bones, soft tissues, and kidneys. It is almost always caused by forms of vitamin D that require a doctor's prescription.
- Hypercalcemia (excess calcium in the blood)
- Hypercalciuria (excess calcium in the urine)
- Hypertension (high blood pressure)
- Polydipsia (excessive thirst)
- Polyuria (passing large amounts of urine)
Tests to confirm the diagnosis:
- 1,25 dihydroxyvitamin D levels
- 25-hydroxyvitamin D levels
- Serum calcium
- Serum phosphorus
- X-ray of the bone
Stop taking vitamin D. Consult your physician. In severe cases, other treatment may be necessary.
Call your health care provider if you or your child show symptoms of hypervitaminosis D and you have been taking vitamin D in excess of the recommended daily allowance. Also call if you or your child show symptoms and you have been taking a prescription form of vitamin D.
