Vitamin D Toxicity

Vitamin D toxicity is a condition in which the body’s level of vitamin D is too high. This condition may result in altered mental status. It may cause confusion, depression, psychosis, and coma. One case report describes a 64-year-old man who was diagnosed with vitamin D toxicity. He displayed altered mental status, but the condition gradually improved and his calcium levels returned to normal within 18 days.

Vitamin D toxicity can lead to kidney and bone problems. Patients with high levels of vitamin D in their blood may develop a condition called hypercalcaemia. This condition is classified as a medical emergency, and treatment involves the reduction of vitamin D intake and dietary calcium. In severe cases, treatment may also include corticosteroids and bisphosphonates.

The primary symptom of vitamin D toxicity is an accumulation of calcium in the blood. Patients may experience confusion, agitation, or frequent urination. As the calcium builds up in the blood, the condition can progress to kidney failure, calcium stones, and bone pain. Treatment includes restricting vitamin D intake, restriction of dietary calcium, intravenous fluids, and medications.

Vitamin D toxicity is rare in healthy people. Most cases are the result of excessive supplementation. Exposure to the sun or tanning beds does not cause this condition. Vitamin D supplements are often taken as a means to treat vitamin D deficiencies. Vitamin D supplements can also be prescribed to treat seasonal affective disorder and depression.
