What are the Causes of Maternal Hyperparathyroidism?
The most common cause of maternal hyperparathyroidism is a benign tumor called a parathyroid adenoma. Other causes may include hyperplasia of the parathyroid glands or, rarely, parathyroid carcinoma. Genetic conditions such as multiple endocrine neoplasia (MEN) type 1 or type 2 can also predispose individuals to hyperparathyroidism.
