Large pituitary tumors — those measuring about 1 centimeter slightly less than a half-inch or larger — are known as macroadenomas. Smaller tumors are called microadenomas. Because of the size of macroadenomas, they can put pressure on the normal pituitary gland and nearby structures.

Functioning pituitary tumors cause an overproduction of hormones.

What does it do?

Different types of functioning tumors in your pituitary gland cause specific signs and symptoms and sometimes a combination of them. ACTH tumors produce the hormone adrenocorticotropin, which stimulates your adrenal glands to make the hormone cortisol. Cushing's syndrome results from your adrenal glands producing too much cortisol.

Possible signs and symptoms of Cushing's syndrome include:. Overproduction of prolactin from a pituitary tumor prolactinoma can cause a decrease in normal levels of sex hormones — estrogen in women and testosterone in men. Excessive prolactin in the blood affects men and women differently. When a pituitary tumor overproduces thyroid-stimulating hormone, your thyroid gland makes too much of the hormone thyroxine.

This is a rare cause of hyperthyroidism or overactive thyroid disease. Hyperthyroidism can accelerate your body's metabolism, causing:.

Pituitary Gland and Pituitary Tumors

If you develop signs and symptoms that might be associated with a pituitary tumor, see your doctor. Pituitary tumors often can be treated to return your hormone levels to normal and alleviate your signs and symptoms.

If you know that multiple endocrine neoplasia, type 1 MEN 1 runs in your family, talk to your doctor about periodic tests that may help detect a pituitary tumor early. The pituitary gland and the hypothalamus are situated within the brain and control hormone production. The cause of uncontrolled cell growth in the pituitary gland, which creates a tumor, remains unknown. The pituitary gland is a small, bean-shaped gland situated at the base of your brain, somewhat behind your nose and between your ears. Despite its small size, the gland influences nearly every part of your body.

Non-Functioning Pituitary Adenoma

The hormones it produces help regulate important functions, such as growth, blood pressure and reproduction. A small percentage of pituitary tumor cases run in families, but most have no apparent hereditary factor. Still, scientists suspect that genetic alterations play an important role in how pituitary tumors develop.

People with a family history of certain hereditary conditions, such as multiple endocrine neoplasia, type 1 MEN 1 , have an increased risk of pituitary tumors. In MEN I, multiple tumors occur in various glands of the endocrine system. Genetic testing is available for this disorder.
