Hyperparathyroidism means that the level of parathyroid hormone measured in the blood is high. Parathyroid hormone is largely responsible for keeping the calcium level balanced. When there is more parathyroid hormone, the parathyroid glands are trying to raise the calcium level. Hyperparathyroidism is associated with a variety of symptoms, including osteoporosis, kidney stones, stomach pain, fatigue, weakness, concentration and mood problems, and more.
Secondary hyperparathyroidism is a term used when parathyroid hormone levels are high because of a reason other than abnormal function of the parathyroid glands (primary hyperparathyroidism). There can be many reasons for this, such as low vitamin D. Many patients with kidney disease will have secondary hyperthyroidism, because the kidneys play an important role in creating vitamin D.
Secondary hyperparathyroidism can look similar to primary hyperparathyroidism on initial testing. It is imperative to determine the cause of hyperparathyroidism, to see if it is correctable. Our experts understand that a careful evaluation needs to be performed to determine if surgery is necessary.
