Causes of Hypercalcemia Mnemonic [CHIMPANZEES]

Causes of Hypercalcemia Mnemonic [CHIMPANZEES]

Easily memorize the causes of hypercalcemia using the mnemonic “CHIMPANZEES,” which encapsulates a list of important clinical conditions which often present with an elevated serum Ca+. This medical mnemonic concisely outlines important causes of hypercalcemia as Calcium supplementation, Hyperparathyroidism, Immobilization, Multiple myeloma, Paget’s disease, Acromegaly, Neoplasms, Zollinger-Ellison syndrome, Excess vitamin D intake, Excessive calcium intake, and Sarcoidosis (in short for CHIMPANZEES). By harnessing this mnemonic, doctors and medical students gain a streamlined framework to promptly recognize the diverse origins of elevated serum calcium levels, from overactive parathyroid glands to malignancies and hormonal dysregulation. The “CHIMPANZEES” mnemonic serves as a high-yield diagnostic tool, guiding medical practitioners toward a targeted and precise approach to deciphering the complex jigsaw puzzle of hypercalcemia causation in day-to-day patient encounters.

Each element within the CHIMPANZEES mnemonic corresponds to a distinct etiological factor, providing a rapid snapshot of potential underlying causes of hypercalcemia. By weaving together diverse contributors to hypercalcemia, ranging from neoplastic processes to endocrine disorders, this mnemonic empowers healthcare practitioners with a concise, efficient, and memorable tool for timely diagnosis and tailored medical intervention for optimal treatment outcomes.

We, here at the Medicos Republic, hope that you find this medical mnemonic useful in memorizing the causes of hypercalcemia. We have crafted a pictorial representation of the CHIMPANZEES mnemonic for the causes of hypercalcemia at the end of this article, so do check that out! 🙂
