Hypercalcemia is a condition characterized by an elevated calcium level in the blood. It can result from various causes, but two significant contributors are excessive intake of calcium or vitamin D supplements¹.

Vitamin D toxicity, also known as hypervitaminosis D, is one of the common causes of hypercalcemia. This condition usually arises from the overconsumption of vitamin D supplements, leading to an elevated calcium level in the blood². The key symptoms linked with this condition include nausea, vomiting, weakness, and frequent urination. If not addressed, it can progress to more serious health issues, such as bone pain and kidney complications, including the formation of calcium stones³.

In some cases, conditions like sarcoidosis can exacerbate hypercalcemia when compounded by vitamin D supplementation. Such events underline the risk of hypercalcemia in individuals with already heightened vitamin D levels due to their medical condition⁴.

Management of hypercalcemia often involves discontinuing vitamin D intake and limiting dietary calcium. Physicians might also prescribe treatments like corticosteroids or bisphosphonates, and employ intravenous fluids to help manage severe cases⁵.

If you have concerns about hypercalcemia or supplementation, it's prudent to consult with a healthcare professional for tailored advice.
