Causes and Risks The pituitary gland is a small structure that is located at the base of the brain. It is attached by a stalk to the hypothalamus , an area of the brain that controls the function of the pituitary gland. The hormones secreted by the pituitary and their functions are: growth hormone (GH), which stimulates growth of tissues and bone thyroid stimulating hormone (TSH), which stimulates the thyroid gland to secrete hormones that affect body metabolism adrenocorticotropic hormone (ACTH), which stimulates the adrenal gland to secrete hormones that affect metabolism prolactin , which stimulates female breast development and milk production luteinizing hormone (LH), which controls sexual function in males and females follicle stimulating hormone (FSH), which controls sexual function in males and females

However, replacement of deficient hormones is still often required even after successful treatment of a pituitary tumor. Hormone therapy is needed to replace hormones no longer made by organs under the control of the pituitary gland. These include corticosteroids (cortisol), thyroid hormone, sex hormones ( testosterone for men and estrogen for women), and growth hormone in children. Drugs are available to treat associated infertility in men and women. Prognosis Hypopituitarism is usually permanent and requires life-long treatment; however, a normal life span can be expected. Complications Side effects of drug therapy can develop. Call Your Health Care Provider If: Call your health care provider if symptoms of hypopituitarism develop. Ency. home

About The Pituitary Foundation Pituitary Foundation Fact Sheet Hypopituitarism Hormone deficiency caused by the inadequate secretion of one or more of the hormones normally secreted by the pituitary, is known as hypopituitarism. It may be caused by compression of the normal tissue by a developing tumour, surgery, or radiotherapy. If hypopituitarism is caused by tumour compression, function may be partially or fully recovered after surgery or medical therapy to reduce the size of the tumour. Surgically-induced hypopituitarism may occur in some cases, particularly if the tumour is large, but this can be transitory and some or all of the function may recover. Hypopituitarism may also develop after several years of treatment of a pituitary tumour by radiotherapy.

National Conferences Index LINKS Skip main links The Endocrine System Pituitary Disorders Resources ... About The Pituitary Foundation Hypopituitarism Professor Jayne Franklyn University of Birmingham The pituitary gland is the most important endocrine gland in the body, as it produces several important hormones. In turn, these hormones control most of the other hormone systems in the body. The hormones produced by the anterior pituitary include growth hormone (GH), thyroid stimulating hormone (TSH), adrenal stimulating hormone (also known as adrenocorticotrophic hormone or ACTH), luteinising hormone (LH) and follicle stimulating hormone (FSH) (also known as the gonad stimulating hormones or gonadotrophins) and prolactin (Prl). The posterior pituitary produces a hormone called vasopressin (also known as anti-diuretic hormone or ADH). The most common causes of hypopituitarism are tumours of, or close to, the pituitary. The vast majority of these tumours are non-functional i.e. the tumour itself does not produce any hormones, but tumours also occur that overproduce one of the other hormones produced by the pituitary e.g. prolactinoma. If these tumours compress and damage the normal pituitary tissue, the pituitary can no longer function normally and this results in deficiency of the pituitary hormones (hypopituitarism). The term panhypopituitarism refers to deficiency of all the pituitary hormones. Other causes of hypopituitarism include trauma (usually caused by a significant head injury), radiotherapy, pituitary infarction and very rare diseases or infections such as sarcodosis.

Anterior Pituitary Deficiency Syndromes 90% of cases are caused by destruction of the anterior pituitary In general, more than 75% of the anterior pituitary tissue must be destroyed to produce symptoms of hormone deficiency. Panhypopituitarism results, a syndrome of multiple simultaneous endocrine deficiencies (thyroid, adrenal, gonadal). Causes of pituitary destruction: Replacement/compression of normal pituitary by non-functioning anterior pituitary tumors (tend to be large at discovery) Sheehan's syndrome (postpartum pituitary necrosis) Infarction of hypertrophic pituitary due to obstetric hemorrhage or shock. The pituitary is normally hypertrophic in pregnancy; the increase in pituitary size increases its metabolic requirements and also increases pressure in the sella turcica. Thus the pituitary is susceptable to decreases in blood pressure related to problems during delivery. Also can occur with DIC, sickle cell anemia, cavernous sinus thrombosis and other vascular disorders. Symptoms may require years to develop after the initial damage. Empty Sella Syndrome (uncommon) Compression of the pituitary by herniated arachnoid, infarction of an anterior pituitary adenoma, or infarction with Sheehan's syndrome may lead to pituitary destruction.

MAIN SEARCH INDEX Hypopituitarism Definition Description Causes and symptoms Diagnosis ... Resources Definition Hypopituitarism is loss of function in an endocrine gland due to failure of the pituitary gland to secrete hormones which stimulate that gland's function. The pituitary gland is located at the base of the brain. Patients diagnosed with hypopituitarism may be deficient in one single hormone, several hormones, or have complete pituitary failure. Description The pituitary is a pea-sized gland located at the base of the brain, and surrounded by bone. The hypothalamus, another endocrine organ in the brain, controls the function of the pituitary gland by providing "hormonal orders." In turn, the pituitary gland regulates the many hormones that control various functions and organs within the body. The posterior pituitary acts as a sort of storage area for the hypothalamus and passes on hormones that control function of the muscles and kidneys. The anterior pituitary produces its own hormones which help to regulate several endocrine functions. In hypopituitarism, something interferes with the production and release of these hormones, thus affecting the function of the target gland. Commonly affected hormones may include:

MCG Health System Phone Numbers: (706) 721-CARE 1-800-736-CARE Request an Appointment Online Endocrinology Hypopituitarism What is hypopituitarism? Hypopituitarism, also called an underactive pituitary gland, is a condition that affects the anterior lobe of the pituitary gland usually resulting in a partial or complete loss of functioning of that lobe. The resulting symptoms depend on which hormones are no longer being produced by the gland. Because the pituitary gland affects the other endocrine organs, effects of hypopituitarism may be gradual or sudden and dramatic. What are the symptoms of hypopituitarism? Symptoms vary depending on what hormones are insufficiently produced by the pituitary gland. The following are common symptoms associated with reduced production of certain hormones: insufficient gonadotropins production (luteinizing hormone and follicle-stimulating hormone) In premenopausal women, this leads to absent menstrual cycles, infertility, vaginal dryness, and loss of some female characteristics. In men, this deficiency leads to impotence, shriveling of testes, decreased sperm production, infertility, and loss of some male characteristics. insufficient growth hormone production There is currently a great deal of research concerning adult growth hormone deficiency. Whether it should be treated is not yet clear. In children, this deficiency can lead to stunted growth and dwarfism.

Hypopituitarism PITUITARY TUMOR PROGRAM PITUITARY DIAGNOSES INDEX Hypopituitarism is a general term that refers to any underfunction of the pituitary gland. This is a clinical definition used by endocrinologists and is interpreted to mean that one or more functions of the pituitary are deficient. The term may refer to both anterior and posterior pituitary gland failure. Causes of hypopituitarism Deficiency of ACTH and cortisol Deficiency of ACTH resulting in cortisol deficiency is the most dangerous and life threatening of the hormonal deficiency syndromes. With gradual onset of deficiency over days or weeks, symptoms are often vague and may include weight loss, fatigue, weakness, depression, apathy, nausea, vomiting, anorexia and hyperpigmentation. As the deficiency becomes more serious or has a more rapid onset, (Addisonian crisis) symptoms may include confusion, stupor, psychosis, abnormal electrolytes (low serum sodium, elevated serum potassium), and vascular collapse (low blood pressure and shock) which can be fatal. Treatment consists of cortisol administration or another similar steroid (like prednisone) in a tightly regulated manner. For patients with acute adrenal insufficiency (Addisonian crisis), rapid intravenous administration of high dose steroids is essential to reverse the crisis. Deficiency of TSH and thyroid hormone Deficiency of thyroid hormone causes a syndrome consisting of decreased energy, increased need to sleep, intolerance of cold (inability to stay warm), dry skin, constipation, muscle aching and decreased mental functions. This constellation of symptoms is very uncomfortable and is often the symptom complex that drives patients with pituitary disease to seek medical attention. Replacement therapy consists of thyroxin (Syntroid), which is monitored by blood levels of thyroid hormone.

Diabetes Clinic Endocrinology Endocrinologists Diabetes and Other Endocrine and Metabolic Disorders Hypopituitarism Panhypopituitarism In some cases, the production of all of the pituitary hormones decreases or stops, usually due to damage to the entire pituitary gland. This condition is called panhypopituitarism. What is hypopituitarism? Hypopituitarism, also called an underactive pituitary gland, is a condition that affects the anterior (front) lobe of the pituitary gland - usually resulting in a partial or complete loss of functioning of that lobe. The resulting symptoms depend on which hormones are no longer being produced by the gland. Because the pituitary gland affects the other endocrine organs, effects of hypopituitarism may be gradual, or sudden and dramatic. What causes hypopituitarism? Hypopituitarism, in children, is often caused by a benign (non-cancerous) pituitary tumor, an injury, or an infection. However, often no exact cause can be determined. What are the symptoms of hypopituitarism? The symptoms of hypopituitarism vary depending on which hormones are insufficiently produced by the pituitary gland. In addition, the symptoms of hypopituitarism in children will vary depending on their age. Each child may also experience symptoms differently. The following are common symptoms associated with reduced production of certain hormones:

Recommendations Hypopituitarism is a general term that refers to any under-performance of the pituitary gland. This is a clinical definition used by endocrinologists and is interpreted to mean that one or more functions of the pituitary are deficient. The term may refer to both anterior and posterior pituitary gland failure. Deficient pituitary gland function can result from damage to either the pituitary or the area just above the pituitary, namely the hypothalamus . The hypothalamus contains releasing and inhibitory hormones that control the pituitary. Since these hormones are necessary for normal pituitary function, damage to the hypothalamus can also result in deficient pituitary gland function. Injury to the pituitary can occur from a variety of insults, including damage from an enlarging pituitary tumor, irradiation of the pituitary gland, limited blood supply (as experienced in a stroke ), trauma or abnormal

In some cases hypopituitarism is inherited. When the pituitary is affected during the time of skeletal growth, abnormalities of bone development occur. Delay in the appearance and growth of ossification centres as well as in their fusion and disappearance is characteristic. The growth plate remains open and its metaphyseal side is "closed off" as bone abuts on the cartilaginous tissue. Immature body proportions and facial features, abnormal distribution of fat, and delay in eruption of secondary teeth are among the features of hypopituitarism.

In children hypopituitarism may be caused by the presence of tumours, such as craniopharyngioma , optic chiasm or hypothalamic glioma, or germinoma. Unlike adults hypopituitarism secondary to pituitary microadenoma or macroadenoma is rare in childhood. Hypopituitarism may also be seen after surgery particularly for lesions in the suprasellar cistern. Congenital abnormalities, such as pituitary hypoplasia or aplasia may also occur. Pituitary aplasia is usually fatal at birth. Hypoplasia results in varying degrees of hypopituitarism including adenohypophyseal and neurohypophyseal deficiencies. Many of these patients are found to have a small pituitary gland and fossa and the posterior pituitary may be in an ectopic position, usually in the region of the pituitary infundibulum or hypothalamus. These anomalies may only be detected by high resolution coronal and sagittal MR imaging of the pituitary region. An ectopic pituitary is seen as a bright spot in the region of the tuber cinereum on sagittal T1-weighted sequences with concomitant absence of the normal posterior pituitary bright spot in the pituitary fossa. The pituitary fossa may be small and appear empty, an 'empty sella'. The condition may be associated with
