Hypercalcemia is a condition where there is too much calcium in the blood. Calcium is essential for many bodily functions, but too much can lead to serious health issues.

Pathophysiology

  • Structure: Calcium is mainly stored in bones, with small amounts in the blood and soft tissues.
  • Blood: Normal calcium levels in the blood range from 8.5 to 10.2 mg/dL. Hypercalcemia occurs when levels exceed 10.2 mg/dL.
  • Nerve Supply: Calcium plays a crucial role in nerve function, helping transmit signals between nerves and muscles.

Types of Hypercalcemia

  1. Primary Hyperparathyroidism: Excessive production of parathyroid hormone (PTH).
  2. Malignancy-associated Hypercalcemia: Often caused by certain cancers.
  3. Vitamin D Intoxication: Too much vitamin D can increase calcium absorption.
  4. Familial Hypocalciuric Hypercalcemia: A genetic condition affecting calcium regulation.
  5. Other Types: Include granulomatous diseases, endocrine disorders, etc.
