Term

Parathyroid glands produce parathyroid hormone. This hormone helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. Two conditions might develop due to Parathyroid Gland Disorder: 1-      Hyperparathyroidism: Primary hyperparathyroidism occurs due to overproduction of parathyroid hormone (PTH) which causes high calcium levels in the blood leads to a variety of health problems.  Or Secondary hyperparathyroidism occurs due to another disease that first causes low calcium levels in the body.  Over time, increased parathyroid hormone levels occur. 2-    Hypoparathyroidism: uncommon condition in which your body produces abnormally low levels of parathyroid hormone (PTH) leads to abnormally low calcium levels in your blood and bones and to an increase of phosphorus in your blood.
