      when one or more of these glands produce too much PTH
      (parathyroid hormone), which causes hypercalcemia (too
      much calcium in the blood) derived from our bones where
      most calcium is stored.
         Our body uses calcium to maintain healthy bones, and
      is critically important in keeping nerves, muscles, heart and
      blood vessels in working order. When calcium is lost from
      the bones the result is weakening of them, thus increasing
      the risk of fractures. At the same time, the body tries to
      absorb more calcium from food. The kidneys, instead of
      flushing excess calcium into the urine, will retain it with
      the result of increased calcium deposited in the kidneys and
      a high risk of developing kidney stones. There are 100,000
      cases of this disease annually in the United States with
      postmenopausal women most at risk.
         There are two types of hyperparathyroidism–primary
      and secondary. In the much more common primary form
      of the disease, these glands produce too much of the PTH
      hormone (Hyperplasia) with an increase of calcium in the
      blood. Just one of the four glands may be responsible, with
