Medical Services » Pituitary Disorders

The pituitary gland is a small pea-sized gland located at the base of the brain and is the “master gland” of the endocrine system. Its function is to control the production of a variety of hormones that affect growth and other bodily functions. These hormones stimulate other glands like the adrenal, thyroid and reproductive glands.

Types of Pituitary Disorders

Many of the conditions that affect the pituitary gland are congenital, meaning they occur at birth. There are some that evolve over time or the symptoms are noticed over months or years. Other pituitary problems are related to tumors. Fortunately, 99 percent of pituitary-related tumors, referred to as pituitary adenomas, are benign. Pituitary adenomas are classified as functioning and non-functioning.

Functioning adenomas also known as secretory tumors are those that produce too much hormone. Non-functioning adenomas, or non-secretory tumors, do not affect hormone production.

Common Hormones of the Pituitary Gland

GH = Growth Hormone
TSH = Thyroid Stimulating Hormone
ACTH = Adrenocorticotropic Hormone
LH = Leutinizing Hormone
FSH = Follicle Stimulating Hormone
ADH = Antidiuretic Hormone (also called arginine vasopressin, AVP, or vasopressin)
Prolactin
Oxytocin

As with many types of tumors, not all pituitary adenomas affect normal activities but as a tumor grows, it may cause a variety of conditions.

Symptoms of Pituitary Disorders

Pituitary disorders cause a range of symptoms that may develop over time. Functioning or non-functioning adenomas typically cause symptoms due to the following:

Hypersecretion – hormone overproduction
Hormone deficiency – hormone underproduction
Tumor mass effects – growing tumor presses against glands or other areas of the brain

While symptoms may vary, the most common ones include:

Hypersecretion

Breast milk discharge
Accelerated growth
Anxiety or Depression
Decreased urination
Excess sweating
High blood sugar
Increased body hair
Joint Pain

Hormone Deficiency

Excessive urination
Dizziness
Dry skin
Fatigue
Hair loss
Irregular periods (female)
Low energy
Low sex drive
Poor growth
Stunted growth

Tumor Mass Effects

Headaches
Nausea
Vision problems

Causes of Pituitary Disorder

Non-cancerous tumors that trigger the body to create too much or too little hormone are the main cause of pituitary disorders. Other causes include, head injury, bleeding near the pituitary gland and some medications.

Diagnosis

When a person experiences the symptoms of pituitary disorders, a comprehensive review of their medical history will be evaluated along with a thorough physical examination to establish a diagnosis. The examination will include blood tests and in some cases a brain scan will be ordered to search for a tumor and then identify its size and scope.

Treatment

Once a diagnosis has been established, treatments may include prescription hormone therapy, surgery, radiation therapy or a combination of these methods.
