Pituitary Tumor Symptoms & Treatment The pituitary gland is sometimes called the master endocrine gland  because it makes hormones that affect the way many parts of the body work. It also controls hormones made by many other glands in the body.Pituitary tumors are divided into three groups: 1  Benign pituitary adenomas: Tumors that are not cancer.2  These tumors grow very slowly and do not spread from the pituitary gland to other parts of the body.t also controls hormones made by many other glands in the body.

What Are Pituitary Tumors? Most pituitary tumors begin in the larger, front part of the pituitary gland known as the anterior pituitary. This part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood.2  If too much is made in a child they will grow very tall. 3  Normally, adults make only small amounts of growth hormone. This condition is called acromegaly. 2  Thyroid-stimulating hormone (TSH, also called thyrotropin) stimulates growth of the thyroid gland and the release of thyroid hormone. 3  Thyroid hormone regulates metabolism. 4  Too much makes you hyperactive and shaky, and too little makes you sluggish.

Overview 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. In women, prolactinoma might cause:

- Functional (hormone-producing) pituitary adenomas excessively secrete one or more hormones - prolactin, growth hormone (GH), adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Nonfunctional pituitary adenomas do not secrete hormones.

Prolactinoma (Pituitary Tumor) Prolactinomas are the most common type of pituitary tumor. Symptoms of prolactinoma are caused by pressure of the tumor on surrounding tissues or by excessive release of prolactin from the tumor into the blood (causing a condition known as hyperprolactinemia).

Hypopituitarism Treatment of hypopituitarism depends on what is causing it. The goal of treatment is have the pituitary gland work as it should. Treatment may include: Hormone replacement therapy; Surgery to remove a tumor; Radiation therapy; When should I call my health care provider? Tell your health care provider if your symptoms get worse or you have new symptoms. Key points about hypopituitarism. Hypopituitarism happens when the pituitary gland is not active enough. It does not make enough hormones. Hypopituitarism can directly affect the pituitary gland. Or it can indirectly affect the gland through changes in the hypothalamus. Symptoms depend on which hormones the pituitary gland is not making enough of.

Pituitary Disorders The goals for treatment of a pituitary tumor include reduction or complete removal of the tumor, elimination of mass effect, normalization of hormone hypersecretion, and restoration of normal pituitary function.

Pituitary tumors (adenoma, craniopharyngioma, rathke cyst) Prolactin-producing tumors. The most common pituitary tumor, a prolactinoma, causes an overproduction of prolactin, a hormone that helps control sexual function. In women, the tumor can cause menstruation to stop (amenorrhea) or inappropriate production of milk by the breasts (galactorrhea).

What Are Pituitary Gland Tumors? Large Tumor Symptoms. The pituitary gland is tucked in a small area just below your brain. It’s very close to the optic nerves, which carry messages between the brain and eyes. There’s not much room for anything else in there, so large tumors cause issues just because of their size.

Pituitary Gland The pituitary gland is a small endocrine organ that controls a multitude of important functions in the body. It is divided into an anterior lobe, intermediate lobe and posterior lobe, all of which are involved in hormone production.he pituitary gland is involved in several functions of the body including: 1  Growth Hormone Production. 2  Production of Hormones That Act on Other Endocrine Glands. 3  Production of Hormones That Act on the Muscles and the Kidneys. 4  Endocrine Function Regulation. 5  Storage of Hormones Produced by the Hypothalamus.

Overview Pituitary tumors are abnormal growths that develop in your pituitary gland. Some pituitary tumors result in too many of the hormones that regulate important functions of your body. Some pituitary tumors can cause your pituitary gland to produce lower levels of hormones. Most pituitary tumors are noncancerous (benign) growths (adenomas). Adenomas remain in your pituitary gland or surrounding tissues and don't spread to other parts of your body.

- While roughly the size of a pea, the pituitary gland produces hormones that regulate many body functions, including energy and metabolism, sexual development and functioning, bone mass, blood pressure, body growth, and the production of breast milk in women.ther tumors are nonfunctioning, which means that they do not secrete hormones. If a pituitary tumor is large, pressing on the normal portion of the pituitary gland, it can create problems in the normal secretion of hormones.

- Pituitary hormone deficiencies-(not enough of one or more hormones made by the pituitary gland). As the pituitary adenoma grows, it can damage normal pituitary tissue. This can cause the pituitary gland to make fewer hormones than normal. The pituitary gland might be damaged permanently.

What Are Pituitary Tumors? Pituitary adenomas can be divided into 2 categories based on size: 1  Microadenomas are tumors that are smaller than 1 centimeter (cm) across. 2  Macroadenomas are tumors 1 cm across or larger. Macroadenomas can affect a person’s health in 2 ways. First, they can cause symptoms if they make too much of a certain hormone. Second, they can cause symptoms by pressing on normal parts of the pituitary or on nearby nerves, such as the optic nerves.
