Surgery is the preferred treatment. Usually 3 and 1/2 glands are removed. The remaining tissue may be implanted in the forearm so a doctor can easily operate on it if symptoms come back. This tissue will also help the body control calcium levels.
Increased calcium levels persist or return about 20% of the time after surgery.
Parathyroid hyperplasia causes about 15% of cases of hyperparathyroidism, which leads to an increase in blood calcium levels.
Patients may also have complications from the other endocrine tumors that are part of the multiple endocrine neoplasia syndromes. See:
