Pituitary disease For example, insufficient production (hyposecretion) of thyroid stimulating hormone (TSH) in the pituitary gland will cause hypothyroidism, while overproduction (hypersecretion) of TSH will cause hyperthyroidism.

Pituitary Disorders Hypopituitarism. Pituitary adenomas are the most common cause of hypopituitarism, but other causes include parasellar diseases, pituitary surgery, radiation therapy, inflammatory and granulomatous diseases, and head injury.

[Anterior pituitary hypersecretion syndromes]. Anterior pituitary hypersecretion can be due to abnormal hypothalamic regulation, decreased peripheral hormone feedback or pituitary tumor. In some cases hypersecretion gives rise to a typical clinical syndrome involving acromegaly, hyperprolactinemia, and excess corticotropin (ACTH).The etiology of acromegaly is a growth hormone (GH)-secreting pituitary tumor in the vast majority of cases.Hyperprolactinemia and excess cortisol, however, may be due to many causes among which prolactin (PRL)- and ACTH-secreting pituitary tumors are not frequent.nterior pituitary hypersecretion can be due to abnormal hypothalamic regulation, decreased peripheral hormone feedback or pituitary tumor. In some cases hypersecretion gives rise to a typical clinical syndrome involving acromegaly, hyperprolactinemia, and excess corticotropin (ACTH).

Disorders Pituitary tumors (also called pituitary adenomas) can result in hormonal overproduction causing serious endocrine disturbances such as acromegaly (excess GH), Cushing's disease (excess ACTH) or prolactinoma (excess prolactin).

Hypopituitary This condition may occur because of disease in the pituitary or hypothalamus (a part of the brain that contains hormones that control the pituitary gland). When there is low or no production of all the pituitary hormones, the condition is called panhypopituitarism. This condition may affect either children or adults.The pituitary gland sends signals to other glands (eg, thyroid gland) to produce hormones (eg, thyroid hormone).hen there is low or no production of all the pituitary hormones, the condition is called panhypopituitarism.

- Cushing’s disease is a form of Cushing’s syndrome Cushing’s disease is the most common form of endogenous Cushing’s syndrome. It is caused by a tumor in the pituitary gland that secretes excessive amounts of a hormone called Adrenocorticotropic hormone, or ACTH. 1,4 Fortunately, this type of tumor is typically benign.

Disorders Because of the close proximity of the pituitary gland to these major intracranial nerves and blood vessels, as well as the vital hormonal control the pituitary gland provides, disorders of the pituitary can cause a wide spectrum of symptoms, both hormonal and neurological.

Pituitary Gland Disorders and Tumors They can also compress the optic nerve, causing visual problems and headaches. Other conditions can also result in pituitary problems. Tumors in the pituitary region,infections and autoimmune conditions can affect the pituitary gland and cause headaches, visual problems and hormonal abnormalities. Select a link below to learn more:

Pituitary disorders Cushing's disease is a rare condition caused by an overproduction of the adrenal hormone cortisol. The most common form of Cushing's disease is due to an excess secretion of the pituitary hormone, ACTH (adrenocorticotropic hormone), which circulates in the blood and stimulates the adrenal gland.ituitary disorders. The pituitary is a small gland (about the size of a kidney bean) located at the base of the brain, just beneath the optic (eye) nerve in a bony area called the sella turcica.

What Are Pituitary Gland Tumors? Large tumors put pressure on the area around the pituitary gland and cause: 1  Headaches. 2  Problems with eyesight, especially loss of peripheral vision (what you can see off to the side even as you look straight ahead) and double vision.

- A tumor in the pituitary gland causes symptoms by either releasing too much of a hormone or by pressing on the gland causing it to release too little hormone. A pituitary tumor may also cause symptoms by growing and pressing on the structures, like the nerves to the eyes, surrounding the gland.

Hypopituitarism: Causes, Signs, Symptoms, Expert Views, Diagnosis and Treatment This leads to visual disturbance as well as interference with hormone production. Causes of hypopituitarism include diseases and pituitary damage through events like: Brain surgery. Head injury. Pituitary tumors. Stroke. Hypophysitis. Radiation. Tuberculosis.

- Pituitary infarction is usually acute (short period of symptoms) and can be life-threatening. Symptoms are usually acute and include severe headache, ophthalmoplegia (paralysis of the eye muscles causing double vision), and symptoms of acute adrenal insufficiency (low blood pressure, nausea, and vomiting).

Pituitary Disorders The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain. As the “master gland” of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating (causing) other glands to produce other hormones.ecretory tumors produce too much of a hormone normally made by the pituitary, and non-secretory tumors do not. Both types of tumors can cause problems if they are large and interfere with normal function of the pituitary gland and/or nearby structures in the brain.

New Tumor Classifications Benign (non-cancerous) tumors called adenomas are the most common type of pituitary tumor. Even though they are not cancerous, these tumors can cause health problems in several ways: 1  By damaging the healthy pituitary gland.2  By making too many pituitary hormones.3  By pressing on nerves that control vision or other functions.raniopharyngiomas are tumors that can damage the hypothalamus, a gland at the base of your brain. They often cause damage in children and young adults, but can occur in adults. These tumors develop from a structure that is present before birth. If the structure does not go away after birth, it can become a tumor.

An Overview of the Adrenal Glands Below are the most common disorders and diseases of the adrenal glands: 1  Addison’s disease: This rare disorder may affect anyone at any age. It develops when the adrenal cortex fails to produce enough cortisol and aldosterone. 2  Adrenal cancer: Adrenal cancer is an aggressive cancer, but it’s very rare.

- Examples of Common Pituitary Disorders. 1  Pituitary tumors: may be hormone-secreting or non-secreting; most are benign; may cause visual disturbances and headaches as they grow and compress surrounding tissues; they often result in excessive amounts of one pituitary hormone and decreases in others.hile most are benign, they can produce excessive amounts of a specific pituitary hormone, crowd out the production of other hormones, and compress surrounding tissues. Blood vessels and the optic nerves are in close proximity to the pituitary gland.

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.
