Hyperparathyroidism 1 C1840402
A condition where overactive parathyroid glands produce excess hormone, leading to high blood calcium levels. It often affects adults and may be treated with surgery, medication, or monitoring.

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Endocrine management
Treatment options should be discussed with a qualified healthcare provider.
Parathyroidectomy
Surgical removal of the overactive parathyroid gland(s) is the primary definitive treatment for primary hyperparathyroidism. Pre-operative localization studies guide the surgical approach, and minimally invasive techniques are often employed when feasible.
Calcimimetic therapy
Cinacalcet is a calcimimetic agent that reduces parathyroid hormone secretion by increasing the sensitivity of calcium-sensing receptors. This treatment is particularly useful for patients who are not surgical candidates or have persistent hyperparathyroidism after surgery.
Additional treatment options
Hydration and activity modification
Adequate fluid intake of 2-3 liters daily helps prevent kidney stones, a common complication of hyperparathyroidism. Weight-bearing exercises support bone health, while avoiding prolonged immobility reduces hypercalcemia risk.
lifestyleCalcium-modified diet
Moderate calcium intake is recommended rather than severe restriction, as the body still requires calcium for essential functions. Working with a dietitian helps balance calcium intake while avoiding high-calcium foods that may exacerbate symptoms.
dietaryRegular biochemical monitoring
For asymptomatic or surgically ineligible patients, regular monitoring of serum calcium, PTH levels, kidney function, and bone density through DXA scans guides treatment decisions and identifies disease progression requiring intervention.
