Hypercalcemia is defined as a condition characterized by an elevated level of calcium in the blood. Normal calcium levels in the bloodstream are essential for various physiological functions, including muscle contraction, nerve conduction, and blood clotting. When calcium levels rise above the normal range, it can lead to several symptoms and complications, such as nausea, vomiting, increased thirst, frequent urination, abdominal pain, and, in severe cases, heart rhythm disturbances or kidney dysfunction.

The condition can occur due to various causes, including overactive parathyroid glands, certain cancers, prolonged immobilization, and excessive intake of calcium or vitamin D. Recognizing hypercalcemia is crucial because it may signify underlying health issues that require prompt medical management. Therefore, the identification of hypercalcemia as raised calcium levels in the blood is key to understanding and addressing the associated risks and treatment options.
