Evaluation and therapy of hypercalcemia.

Area of Science:

• Endocrinology
• Oncology
• Nephrology

Background:

• Hypercalcemia is a prevalent endocrine and metabolic disorder.
• It presents diagnostic and therapeutic challenges.
• Common causes include primary hyperparathyroidism and malignancy.

Purpose of the Study:

• To review the pathophysiology of hypercalcemia.
• To discuss common etiologies in outpatient and inpatient settings.
• To outline current treatment strategies and the importance of addressing underlying causes.

Main Methods:

• Literature review of hypercalcemia.
• Analysis of causes based on patient setting (outpatient vs. inpatient).
• Summary of established and emerging treatments.

Main Results:

• Hypercalcemia results from increased bone resorption or vitamin D-dependent absorption.
• Primary hyperparathyroidism is the most frequent cause in outpatients.
• Malignancy is the leading cause of hypercalcemia in hospitalized patients.

Conclusions:

• Effective management requires addressing the underlying cause, such as parathyroidectomy for hyperparathyroidism or chemotherapy for malignancy.
• Treatment modalities include hydration, bisphosphonates, and calcitonin.
• Understanding the etiology is crucial for successful patient outcomes.
