What is TSH ?

TSH is a hormone that controls thyroid function. It stands for Thyroid Stimulating Hormone.
It is actually produced by the brain’s pituitary gland, but stimulates production of the hormones triiodothyronine (T3) and thyroxine (T4) in the thyroid gland.
 
The amount and balance of these hormones affects almost every physiological process in the body, particular your body’s metabolism.
