The management of hyperparathyroidism is largely dictated by the specific type of disease (primary, secondary, or tertiary) and the presence of symptoms or end-organ damage. For primary hyperparathyroidism, surgery remains the only curative therapy and is the gold standard for suitable candidates. However, management strategies also encompass medical therapies for those unable to undergo surgery, as well as distinct protocols for secondary forms driven by renal failure. This section delves into the surgical criteria, operative techniques, and long-term management plans designed to restore calcium homeostasis and prevent recurrence.
Guidelines established by international endocrine surgery organizations provide clear criteria for who should undergo parathyroidectomy. Surgery is unequivocally recommended for all symptomatic patients—those with kidney stones, fragility fractures, or classic neuromuscular symptoms. For “asymptomatic” patients, surgery is indicated if they meet any of the following: serum calcium > 1.0 mg/dL above the upper limit of normal, creatinine clearance (kidney function) < 60 cc/min, presence of kidney stones or nephrocalcinosis on imaging, osteoporosis (T-score < -2.5) or vertebral fracture, or age younger than 50 years. The age criterion reflects the long-term risk of complications in younger patients if left untreated.
The evolution of parathyroid surgery has moved from bilateral neck exploration (examining all four glands) to minimally invasive parathyroidectomy (MIP). MIP is feasible when preoperative imaging localizes a single adenoma. This approach utilizes a small incision (typically 2-3 cm), results in less postoperative pain, better cosmetic outcomes, and a faster recovery. The procedure is often performed on an outpatient basis. During the surgery, the surgeon targets the pre-identified gland, removing the adenoma while preserving the healthy glands. If the adenoma is not found or if multiple glands are enlarged, the surgeon can convert to a standard exploration to ensure cure.
A critical adjunct to modern surgery is intraoperative PTH monitoring. Because PTH has a very short half-life (3-5 minutes), levels drop rapidly once the source of hypersecretion is removed. Blood samples are drawn before the incision, at the time of gland removal, and 10-15 minutes post-excision. A drop in PTH of more than 50% from the baseline confirms that the curative gland has been removed and that no other hyperactive glands remain. This real-time feedback provides high confidence in the surgical success before the patient leaves the operating room.
Recovery from parathyroidectomy is generally rapid. Most patients report minimal discomfort, often managed with over-the-counter pain relievers. The incision is typically closed with absorbable sutures or surgical glue. Transient hypocalcemia is a potential postoperative issue as the “hungry bones” begin to absorb calcium rapidly now that the PTH drive is gone. Patients are often placed on a tapering regimen of calcium and vitamin D supplements to prevent symptoms of low calcium, such as tingling in the fingertips or lips. Hoarseness is a rare complication related to the recurrent laryngeal nerve, but permanent voice changes are uncommon in experienced hands.
Treatment for secondary hyperparathyroidism, primarily seen in chronic kidney disease (CKD), is initially medical. The goal is to manage the phosphate retention and vitamin D deficiency that drive the parathyroid stimulation. Phosphate binders are used to reduce dietary phosphate absorption, and calcimimetics (medications that mimic calcium) are employed to suppress PTH secretion. Vitamin D analogs (like calcitriol) are administered to suppress the glands directly. Surgery (subtotal parathyroidectomy) is reserved for cases where medical therapy fails to control PTH, or when complications like calciphylaxis (painful skin ulcers from calcium deposits) or severe bone disease develop.
For patients with primary hyperparathyroidism who are poor surgical candidates due to severe comorbidities or advanced age, medical management is an option. It is important to note that medications do not cure the disease but can manage the biochemical abnormalities. The goal is to keep calcium levels safe and protect the bones.
Cinacalcet is a calcimimetic agent that increases the sensitivity of the calcium-sensing receptor on the parathyroid cells to extracellular calcium. This tricks the glands into “thinking” calcium levels are high, thereby inhibiting PTH secretion. It effectively lowers serum calcium and PTH levels in parathyroid carcinoma and primary hyperparathyroidism but does not improve bone density or cure the underlying adenoma. It is a lifelong therapy with potential side effects like nausea.
To address the skeletal risks in non-surgical patients, bisphosphonates (e.g., alendronate) may be prescribed. These drugs inhibit osteoclast activity, preventing bone resorption. They can stabilize or improve bone mineral density at the lumbar spine and hip, reducing fracture risk. However, they generally do not lower serum calcium or PTH levels significantly. A combination of hydration, moderate calcium restriction, and these pharmacological agents constitutes the conservative management approach.
Patients who do not meet surgical criteria and choose observation require rigorous long-term monitoring. This “watch and wait” approach involves measuring serum calcium and creatinine every 6-12 months and conducting bone density scans every 1-2 years. Renal imaging to check for silent kidney stones may also be recommended. If the disease progresses—indicated by rising calcium, deteriorating kidney function, or bone loss—the patient is then referred for surgery. The goal is to intervene before irreversible damage occurs.
Successful surgery leads to a normalization of calcium levels usually within 24 hours. Long-term follow-up focuses on bone density recovery and monitoring for recurrence. Bone density improves significantly in the first year post-op and can continue to improve for up to a decade. Recurrence of primary hyperparathyroidism is rare (< 5%) but can occur years later, often due to the growth of a different gland. Therefore, annual calcium checks are recommended for life. For patients with genetic syndromes, recurrence rates are higher, necessitating closer surveillance.

Yes, surgery to remove the overactive parathyroid gland(s) is the only way to permanently cure primary hyperparathyroidism. Medications can help manage calcium levels and protect bones, but they do not treat the underlying tumor or stop the disease process permanently.
In the hands of an experienced endocrine surgeon, the cure rate for parathyroidectomy is very high, typically exceeding 95-98%. The use of preoperative imaging and intraoperative hormone monitoring has significantly improved outcomes and minimized the need for extensive neck exploration.
Modern minimally invasive techniques allow for very small incisions, often measuring only 1 inch (2.5 cm) or less. Surgeons typically place the incision in a natural skin crease to hide the scar. Over time, the scar usually fades significantly and becomes barely noticeable.
If calcium levels remain high after surgery, it usually means an abnormal gland was missed (persistent disease). This can happen if the gland is in an unusual location (ectopic) or if there are multiple abnormal glands. Further imaging and a re-operative procedure at a specialized center may be required.
Recovery is generally quick. Most patients go home the same day. Sore throat and mild discomfort are common for a few days. Most individuals can return to light activities within a few days and resume full normal activities, including work, within one to two weeks.
