Parathyroid Gland

Our body has four parathyroid glands that sit immediately behind the thyroid gland at the neck region. Parathyroid gland produces parathyroid hormone which regulate the balance of calcium and phosphorous in our body. If there is hyperplasia or tumor of parathyroid gland, there will be excessive secretion of parathyroid hormone which leads to high body calcium level. Patients will have renal stone, renal impairment, low bone mineral mass, bone fracture, ulcer pain, decreased memory, increased urination, constipation, hypertension and even fatality if felt untreated.

Other people may have hypoparathyroidism (too little parathyroid hormone). The most common cause is autoimmune disease and complication after parathyroid surgery. Patient will experience symptoms of low calcium level such as hand and feet numbness, muscle cramp and tetany.
