Pituitary Disorders

What is the Pituitary Gland?

The pituitary gland is a small bean-shaped gland that is situated at the base of the brain, behind the nose and between the ears.
Despite its small size, the pituitary gland produces many hormones that influence nearly every part of the body.
The hormones it produces help regulate important functions, such as growth, blood pressure, and reproduction.


What are Pituitary Tumors?

Pituitary tumors are abnormal growths that develop within the pituitary gland.
Most pituitary tumors are non-cancerous (benign) growths. These growths remain in the pituitary gland and do not spread to other parts of the body.


What Symptoms does Someone with a Pituitary Tumor Have?

Not all pituitary tumors cause symptoms.
Pituitary tumors that make too much hormones can cause a variety of signs and symptoms depending on the hormone they produce.
Some of the symptoms of hormonal excess may include:
     – Irregular or lack of menstrual periods
     – Erectile dysfunction
     – Unintended weight gain
     – Changes in facial appearance
     – High blood sugar levels


Some pituitary tumors can cause the pituitary gland to produce lesser amounts of hormones.
Symptoms related to hormonal deficiency may include:
     – Nausea and vomiting
     – Fatigue or weakness
     – Feeling cold
     – Less frequent or no menstrual periods
     – Erectile dysfunction
     – Unintended weight loss or gain
     – Increased amount of urine


There are also some pituitary tumors that do not affect hormonal balance.
The symptoms these tumors cause are related to their growth and the pressure they put on other surrounding structures.
Some of the symptoms may include:
     – Headache
     – Visual disturbance
