Pituitary is a small pea shaped gland in our brain commonly known as the “master gland” because it controls several other hormone glands in your body, including the thyroid and adrenals, the ovaries and testicles.It secretes hormones like GH, ACTH, Prolactin, TSH and ADH that carry messages from one cell to another through your bloodstream and execute important life sustaining functions.
If your pituitary gland is not producing sufficient amounts of one or more hormones this is called hypopituitarism.
If, on the other hand, you are over-producing certain hormones, then you would have features due to the over production of the specific hormone concerned.
