Question: What are the treatments for Primary Hyperparathyroidism ?
Answer: Surgery
                
Surgery to remove the overactive parathyroid gland or glands is the only definitive treatment for the disorder, particularly if the patient has a very high blood calcium level or has had a fracture or a kidney stone. In patients without any symptoms, guidelines are used to identify who might benefit from parathyroid surgery.3
                
When performed by experienced endocrine surgeons, surgery cures primary hyperparathyroidism in more than 95 percent of operations.2
                
Surgeons often use imaging tests before surgery to locate the overactive gland to be removed. The most commonly used tests are sestamibi and ultrasound scans. In a sestamibi scan, the patient receives an injection of a small amount of radioactive dye that is absorbed by overactive parathyroid glands. The overactive glands can then be viewed using a special camera.
                
Surgeons use two main strategies to remove the overactive gland or glands:
                
- Minimally invasive parathyroidectomy. This type of surgery, which can be done on an outpatient basis, may be used when only one of the parathyroid glands is likely to be overactive. Guided by a tumor-imaging test, the surgeon makes a small incision in the neck to remove the gland. The small incision means that patients typically have less pain and a quicker recovery than with more invasive surgery. Local or general anesthesia may be used for this type of surgery.  - Standard neck exploration. This type of surgery involves a larger incision that allows the surgeon to access and examine all four parathyroid glands and remove the overactive ones. This type of surgery is more extensive and typically requires a hospital stay of 1 to 2 days. Surgeons use this approach if they plan to inspect more than one gland. General anesthesia is used for this type of surgery.
                
Almost all people with primary hyperparathyroidism who have symptoms can benefit from surgery. Experts believe that those without symptoms but who meet guidelines for surgery will also benefit from surgery. Surgery can lead to improved bone density and fewer fractures and can reduce the chance of forming kidney stones. Other potential benefits are being studied by researchers.
                
Surgery for primary hyperparathyroidism has a complication rate of 13 percent when performed by experienced endocrine surgeons.4 Rarely, patients undergoing surgery experience damage to the nerves controlling the vocal cords, which can affect speech. A small number of patients lose all their healthy parathyroid tissue and thus develop chronic low calcium levels, requiring lifelong treatment with calcium and some form of vitamin D. This complication is called hypoparathyroidism. The complication rate is slightly higher for operations on multiple tumors than for a single adenoma because more extensive surgery is needed.
                
People with primary hyperparathyroidism due to familial hypocalciuric hypercalcemia should not have surgery.
                
Monitoring
                
Some people who have mild primary hyperparathyroidism may not need immediate or even any surgery and can be safely monitored. People may wish to talk with their health care provider about long-term monitoring if they
                
- are symptom-free  - have only slightly elevated blood calcium levels  - have normal kidneys and bone density
                
Long-term monitoring should include periodic clinical evaluations, annual serum calcium measurements, annual serum creatinine measurements to check kidney function, and bone density measurements every 1 to 2 years.
                
Vitamin D deficiency should be corrected if present. Patients who are monitored need not restrict calcium in their diets.
                
If the patient and health care provider choose long-term monitoring, the patient should
                
- drink plenty of water  - exercise regularly  - avoid certain diuretics, such as thiazides
                
Either immobilizationthe inability to move due to illness or injuryor gastrointestinal illness with vomiting or diarrhea that leads to dehydration can cause blood calcium levels to rise further in someone with primary hyperparathyroidism. People with primary hyperparathyroidism should seek medical attention if they find themselves immobilized or dehydrated due to vomiting or diarrhea.
                
Medications
                
Calcimimetics are a new class of medications that decrease parathyroid gland secretion of PTH. The calcimimetic, cinacalcet (Sensipar), has been approved by the U.S. Food and Drug Administration for the treatment of secondary hyperparathyroidism caused by dialysisa blood-filtering treatment for kidney failureand primary hyperparathyroidism caused by parathyroid cancer. Cinacalcet has also been approved for the management of hypercalcemia associated with primary hyperparathyroidism.
                
A number of other medications are being studied to learn whether they may be helpful in treating primary hyperparathyroidism. These medications include bisphosphonates and selective estrogen receptor modulators.
