Primary hyperparathyroidism is caused by a condition that affects one or more parathyroid glands causing exaggerated release of its hormone (parathyroid hormone or PTH).  This condition could be a benign tumor of the parathyroid gland called an adenoma, benign enlargement affecting multiple glands (hyperplasia) or very rarely carcinoma (malignant tumor).  The cause of those tumors are unknown with certain theories being exposure to radiation of the head and neck area in the past, lithium use and, rarely, a syndrome that runs in the patient’s family.
