[Hypercalcemia - Diagnosis and Management]

Area of Science:

• Endocrinology
• Internal Medicine
• Oncology

Background:

• Hypercalcemia is a common electrolyte imbalance.
• Accurate diagnosis is crucial for effective management.
• Primary hyperparathyroidism and malignancy are leading causes.

Purpose of the Study:

• To outline the diagnostic approach for hypercalcemia.
• To emphasize key investigations for identifying the etiology.
• To guide therapeutic strategies based on diagnosis.

Main Methods:

• Comprehensive patient history and clinical examination.
• Systematic laboratory testing, including serum calcium and parathyroid hormone levels.
• Differential diagnosis considering common causes like primary hyperparathyroidism and malignancy.

Main Results:

• Serum calcium and parathyroid hormone levels are essential for diagnosis.
• Primary hyperparathyroidism accounts for a significant portion of hypercalcemia cases.
• Malignancy-related hypercalcemia is another major etiological factor.

Conclusions:

• A step-by-step diagnostic workup is necessary for hypercalcemia.
• Identifying the underlying cause (e.g., primary hyperparathyroidism, malignancy) is paramount.
• Treatment is tailored to the specific etiology and severity of hypercalcemia.
