Hyperparathyroidism means that one or more of your four parathyroid glands may be too active. These are tiny glands in the neck, behind the thyroid gland. When they're too active, they make too much parathyroid hormone (PTH). This hormone helps control how much calcium is in your blood.
When a parathyroid gland makes too much PTH, the amount of calcium in your blood goes up. Some of this calcium comes from your bones. That means that hyperparathyroidism can lead to weak bones and a greater risk of broken bones. The extra calcium in the blood can also lead to kidney stones and other health problems.
