Maintaining normal serum calcium levels is crucial for overall health. This review covers calcium regulation, disorders like hypercalcemia and hypocalcemia, and their effective treatments.

Area of Science:

  • Endocrinology and Metabolism
  • Nephrology
  • Gastroenterology

Background:

  • Serum calcium concentration is vital for neurological, gastrointestinal, and renal functions.
  • Normal calcium levels are maintained by tightly regulated ion transport in the kidney, intestines, and bone, mediated by hormones like parathyroid hormone and vitamin D.
  • Disruptions in calcium transport lead to hypercalcemia or hypocalcemia, impacting various bodily functions.

Purpose of the Study:

  • To review the mechanisms of calcium homeostasis.
  • To discuss the differential diagnosis of hypercalcemia and hypocalcemia.
  • To outline appropriate therapeutic strategies for calcium imbalances.

Main Methods:

  • Review of existing literature on calcium metabolism and disorders.

  • Analysis of diagnostic approaches for hypercalcemia and hypocalcemia.
  • Synthesis of current treatment guidelines and pharmacological options.

    • Main Results:

    • Abnormalities in serum calcium can significantly affect multiple organ systems.
    • Accurate measurement of ionized calcium is preferred when possible.
    • Effective treatments exist for both hypercalcemia (e.g., bisphosphonates) and hypocalcemia (calcium and vitamin D supplementation).

    Conclusions:

    • Calcium homeostasis is a complex process involving hormonal regulation and organ system interplay.
    • Prompt diagnosis and tailored treatment based on the underlying cause, severity, and symptoms are essential for managing calcium disorders.
    • Understanding these mechanisms and therapeutic options is key for clinical practice.
