Hyperparathyroidism

Hyperparathyroidism is an endocrine disease in which the body produces very high levels of parathyroid hormone (PTH). PTH is needed to balance the levels of calcium and phosphorus.

Hyperparathyroidism is the opposite of hypoparathyroidism, which is when the body products abnormally high levels of parathyroid hormone.

Types

 * Primary hyperparathyroidism - usually linked to enlarged parathyroid glands or a parathyroid tumor.
 * Secondary hyperparathyroidism - other medical conditions cause abnormally low vitamin D or calcium deficiency, or it cab be caused by chronic kidney disease.
 * Familiar hyperparathyroidism - which is inherited (genetic)

Signs and symptoms

 * depression
 * tiredness
 * feeling thirsty and urinating a lot
 * nausea and appetite loss
 * muscle weakness
 * constipation
 * abdominal pain
 * poor concentration
 * mild confusion

Hypoparathyroidism can cause abnormally high levels of calcium, known as hypercalcaemia, which causes further medical problems.
