Symptoms Of Osteitis Fibrosa Cystica

Osteitis fibrosa cystica is not so much a disease in its own right but a complication of hyperparathyroidism. This condition results when the parathyroid glands, which are tiny glands found in the thyroid gland, make too much parathyroid hormone (PTH). This hormone is necessary for strong bones, but excess levels lead to weak and deformed bones. Osteitis fibrosa cystica is rare and strikes less than five percent of hyperparathyroidism patients. The two types of hyperparathyroidism that can lead to osteitis fibrosa cystica are primary, where the problem originates in the parathyroid glands themselves, or secondary.
