“Hypoparathyroidism is an uncommon condition in which your body produces abnormally low level of parathyroid hormone (PTH).”
1.] PTH is an key to regulate and maintain the balance of two minerals in your body i.e; calcium and phosphate.
2.] Low production of PTH will lead to low level of calcium in blood and bones and an increase level of phosphorous in your blood and bones.

Basically, there are three types of hypoparathyroidism :
- Primary Hypoparathyroidism : Primary hypoparathyroidism is caused by the disease of parathyroid gland. Most common cause of primary hypoparathyroidism are – surgical procedures involving thyroid, parathyroid, or radial neck dissection for cancer.
- Pseudo Hypoparathyroidism : In pseudo – hypoparathyroidism, the tissue fails to respond to parathyroid hormone though parathyroid gland are usually normal. It is an rare inherited condition with an autosomal dominant character.
- Pseudopseudo Hypoparathyroidism : It is an another rare familial disorder in which all the clinical features of the pseudo hypoparathyroidism are present except that these patients have no hypocalcaemia or hyperphosphataemia and tissue respond normally to parathyroid hormone.
Signs and symptoms of hypoparathyroidism are as follows :
- Tingling and burning in your fingertips, toes and lips
- Fatigue and weakness
- Painful menstrual periods
- Patchy hair loss
- Dry, coarse skin
- Brittle nails
- Depression or anxiety
- Muscle aches or cramps in your legs, feet, face or stomach
- Spasm on your muscle

The goal of treatment is to relive the symptoms and to normalize the level of calcium and phosphorous in your body. A treatment usually includes :
- Oral calcium carbonate tablets
- Vitamin – D as it help body to absorb calcium and eliminate phosphorous.
- Thiazide diuretics as it can decrease the amount of calcium lost through your urine.
- Parathyroid hormone (Natpara).
