Parathyroid hyperplasia is the enlargement of all four parathyroid glands. The parathyroid glands are four glands in the neck that produce parathyroid hormone (PTH). Parathyroid hyperplasia may occur sporadically in people without a family history of the disease or as part of three inherited syndromes:
In the familial syndromes, a mutated gene is passed down in an autosomal dominant fashion. That means you only need to get the gene from one parent to develop the condition. In MEN 1, the problem is associated with other tumors in the pituitary gland and the pancreas. In MEN 2A, the over-activity of the parathyroids is associated with tumors in the adrenal gland or thyroid.
Your doctor will order blood tests to check your calcium, phosphorus, chloride, bicarbonate, and PTH levels. You will also undergo a 24-hour urine test to determine how much calcium is being removed from your body. In addition, bone X-rays and a bone density test can help detect fractures, bone loss, and bone softening.
Surgery is the preferred treatment. Usually 3 ½ glands are removed. The remaining tissue may be implanted in your forearm so a doctor can easily operate on it if your symptoms come back. This tissue will also help your body control your calcium levels.
