Understanding Hyperparathyroidism: From PTH Levels to Parathyroid Removal

The Role of PTH and Calcium Homeostasis

Parathyroid hormone (PTH) is a critical regulator of calcium balance in the human body. Produced by the parathyroid glands, intact PTH helps maintain stable calcium concentrations by increasing calcium release from bone, enhancing absorption in the intestine, and reducing excretion by the kidneys. When PTH levels become abnormally high, the finely tuned system of calcium regulation is disrupted, leading to hyperparathyroidism—a disorder with systemic skeletal and metabolic consequences.

Hyperparathyroidism and Its Clinical Impact

Hyperparathyroidism is characterized by excessive secretion of PTH, most commonly due to a parathyroid adenoma. This benign tumor accounts for nearly 80–85% of primary hyperparathyroidism cases. Elevated PTH levels cause hypercalcemia, which may present with bone pain, kidney stones, gastrointestinal discomfort, and neurocognitive symptoms. Secondary hyperparathyroidism, in contrast, often arises in patients with chronic kidney disease, where persistent hypocalcemia drives parathyroid overactivity. Accurate measurement of intact PTH levels is therefore essential for diagnosis, disease monitoring, and treatment planning.

Parathyroid Adenoma and Surgical Management

Among treatment strategies, surgical parathyroid removal remains the gold standard for managing parathyroid adenoma. Resection of the affected gland normalizes PTH levels, restores calcium balance, and significantly improves patient outcomes. Advances in imaging and intraoperative PTH monitoring now allow for more precise and minimally invasive parathyroidectomy procedures. Postoperative monitoring of intact PTH and serum calcium is critical to confirm surgical success and prevent recurrence or hypocalcemia.

Research Models for Advancing Hyperparathyroidism Studies

Understanding the molecular mechanisms behind parathyroid adenomas and hyperparathyroidism requires advanced experimental systems. Researchers are investigating the genetic drivers of abnormal PTH secretion, calcium-sensing receptor dysfunction, and tumorigenesis pathways. Reliable in vitro and in vivo models are indispensable for studying parathyroid biology and for developing novel therapies beyond surgery.
