Primary hyperparathyroidism is a metabolic disorder in which one or more of the parathyroid glands produces too much parathyroid hormone. This can result in the loss of bone tissue. This condition is more common in women than in men.
A job of the parathyroid hormone is to keep blood calcium levels from going too low. This is done by releasing calcium from bones. The hormone also conserves calcium that would be excreted by the kidneys, and increases how much calcium is absorbed from food. When the hormone overacts, the result is a rise in the blood calcium level. Too much parathyroid hormone causes too much calcium to be released from bone.
When there is a benign tumor in a parathyroid gland, the condition is called a parathyroid adenoma. When more than one parathyroid gland becomes enlarged, the condition is called parathyroid hyperplasia. Both of these conditions are benign (noncancerous).
In some cases, no cause can be found. Some known causes include benign (noncancerous) tumors on the parathyroid glands, or enlargement of the glands.
The following are the most common symptoms of primary hyperparathyroidism. However, each person may experience symptoms differently. Symptoms of too much calcium in the blood may include:
Other serious symptoms may include:
The symptoms of primary hyperparathyroidism may look like other medical conditions or problems. Always consult your doctor for a diagnosis.
The disorder may not have any symptoms or complications. Sometimes this problem is found during a routine blood test as part of a physical exam.
To diagnose primary hyperparathyroidism , you may have a dual X-ray absorptiometry. This test is also called bone densitometry. It is done to determine bone density and to reveal loss of bone tissue. Bone densitometry is also used to continually monitor the disorder.
Specific treatment for primary hyperparathyroidism will be determined by your doctor based on:
Surgery to remove the affected gland may be needed. Treatment may include continual monitoring with bone densitometry to reveal loss of bone tissue, and to determine if surgery may be needed.
