High calcium levels in the blood are referred to as hypercalcemia. This condition can result from a variety of underlying issues, such as overactive parathyroid glands, certain cancers, vitamin D disorders, or excessive intake of calcium or vitamin D supplements. As a result, it can disrupt normal physiological functions and lead to symptoms like nausea, vomiting, confusion, and kidney stones.

Hypocalcemia indicates low calcium levels, while normocalcemia denotes normal calcium levels. Calcium deficiency is a more general term that implies insufficient calcium, which could relate to a range of health issues, but does not specifically convey the context of elevated blood levels. Thus, hypercalcemia is the precise term that accurately describes high calcium levels in the blood.
