What is the Parathyroid Gland? Secondary Hyperparathyroidism Secondary hyperparathyroidism is when a disease unrelated to your parathyroids causes all of your parathyroid glands to become enlarged and overactive. Tertiary Hyperparathyroidism Tertiary hyperparathyroidism is when a patient that previously had secondary hyperparathyroidism now develops primary hyperparathyroidism, ie. Parathyroid cancer Parathyroid cancer is a rare cause of primary hyperparathyroidism.
Your physician will order, at a minimum, the following blood tests if testing for parathyroid disease: Calcium PTH parathyroid hormone Vitamin D OH and vitamin D 1,hydroxy Creatinine Once a diagnosis of primary hyperparathyroidism has been made and a surgeon is evaluating you for parathyroid surgery , parathyroid Imaging will be performed: this may include a parathyroid ultrasound, 3D parathyroid CT scan, or less commonly a Sestamibi scan.
Benefits of having parathyroid surgery include: Improved bone density and decreased risk of bone fractures stabilization of osteoporosis Improved quality of life Lower risk of kidney stones up to 90 percent of patients do not develop any new stones Decreased risk of premature death Disappearance or improvement of symptoms.
Do symptoms improve after parathyroidectomy? Will medication be needed after parathyroid surgery? What kind of follow-up do I need? Can hyperparathyroidism come back?

Hypercalcemia can make you miserable. The most popular page of this large website is the Symptoms of Hyperparathyroidism page. Here is the most important thing to know about the symptoms of hypercalcemia: they are NOT correlated with how high the calcium is.
That is, someone with only a slightly high calcium can feel just as bad as someone with a much higher blood calcium level, and they will have the same chances of getting all of the complications. Some doctors out there do not know this!
In medical school they were taught that the calcium level determined how bad the disease was, so a mild hypercalcemia meant a mild disease and worse hypercalcemia meant worse problems.
In treating tens of thousands of patients with hyperparathyroidism, we know this is not true. Mild hypercalcemia is just as bad as more pronounced hypercalcemia. This is illustrated very nicely in the graph below where we looked at over 20, patients operated on for hyperparathyroidism and hypercalcemia. Hypercalcemia is almost always caused by a parathyroid tumor called primary hyperparathyroidism. Parathyroid glands are tiny endocrine glands in your neck, next to your thyroid. You have four of them, and the only thing they do is control blood calcium levels.
They do this by making parathyroid hormone PTH , which raises the blood calcium level by taking calcium out of your bones. A normal parathyroid gland will produce just enough PTH to keep your blood calcium level in normal range.
A parathyroid tumor will produce more PTH than necessary, which will push the calcium level up. If you have been told that you have hypercalcemia, the overwhelming odds are that you have a parathyroid tumor. There are a few other causes of hypercalcemia, which you can read about on our page on Causes of High Blood Calcium , but they are much, much less common. Hypercalcemia is almost always due to a parathyroid problem. Hypercalcemia is diagnosed by a blood calcium test.
If the calcium is high, then you have hypercalcemia. The next step is to figure out what the cause of hypercalemia is. Since almost all hypercalcemia is caused by a parathyroid problem, the obvious next step is to measure the amount of parathyroid hormone PTH in the blood.
This is a simple blood test. If you have hypercalcemia and a PTH level that is in the high or normal range, then you have a parathyroid tumor. Scans, x-rays, and imaging tests are NOT to be used to diagnose hyperparathyroidism -- it is diagnosed on blood tests alone. We have two very excellent pages on the diagnosis of hyperparathyroidism: 1 The Diagnosis of Hyperparathyroidism , and 2 Advanced Diagnosis Tricks for Hyperparathyroidism.
Since hypercalcemia is almost always due to a parathyroid tumor, and there are no medications that can treat this — the treatment is to remove the tumor. Fortunately, parathyroid surgery is curative and can be done in a minimally invasive outpatient operation. Removing the parathyroid tumor is the only way to cure almost every case of hypercalcemia.
Everyone with primary hyperparathyroidism is a candidate for this operation. There is no reason to wait for these complications to occur. Get the tumor out of your neck before it does damage! Read some of our patient testimonials to learn about how this simple operation can be life-changing.
We know there is a lot of information on the site and it can be hard to take it all in. If you have a question for one of our surgeons, or for our office, we would be happy to help.

Parathyroid glands The parathyroid glands, which lie behind the thyroid, manufacture the parathyroid hormone, which plays a role in regulating your body's levels of the minerals calcium and phosphorus.
