What hormone problems can occur with pituitary tumors?
GaleEncyofMedicine
A pituitary tumor is a build up fluid or tissue that attaches to the pituitary gland . I have a 2mm, it has been there a couple of years but has not grown any. Since this gland produces hormones it has to be regulated very closely and make sure the tumor is not growing. This can cause severe mood swings,erratic behavior, weight loss, and bad swelling of the breast along with leaking dicharge from the breast.There is a meication to help control this.

∙ 10y agoWhile scientists do not know the exact cause of pituitary tumors, they have made great advances in understanding how changes in a person's DNA can cause the pituitary to grow tumors. Some of these DNA changes can include oncogenes being turned on, or tumor suppressor genes being turned off. Some people also inherit gene mutations from their parents which cause pituitary tumors.

Pituitary tumor?
DefinitionA pituitary tumor is an abnormal growth in the pituitary gland, the part of the brain that regulates the body's balance of hormones.Alternative NamesTumor - pituitaryCauses, incidence, and risk factorsMost pituitary tumors are noncancerous (benign). Up to 20% of people have pituitary tumors. However, many of these tumors do not cause symptoms and are never diagnosed during the person's lifetime.The pituitary gland is a pea-sized endocrine gland located at the base of the brain. The pituitary helps control the release of hormones from other endocrine glands, such as the thyroid and adrenal glands. The pituitary also releases hormones that directly affect body tissues, such as bones and the breast's milk glands. These hormones include:Adrenocorticotropic hormone (ACTH)Growth hormone (GH)ProlactinThyroid-stimulating hormone (TSH)As the tumor grows, hormone-releasing cells of the pituitary may be damaged, causing hypopituitarism.The causes of pituitary tumors are unknown. However, some are part of a hereditary disorder called multiple endocrine neoplasia I (MEN I).Other types of tumors that can be found in the same part of the head as a pituitary tumor:CraniopharyngiomasCystsGerminomasTumors that have spread from cancer in another part of the body (metastatic tumors)SymptomsMost pituitary tumors produce too much of one or more hormones. As a result, symptoms of one or more of the following conditions can occur:HyperthyroidismCushing syndromeGigantism or acromegalyNipple dischargeSymptoms caused by pressure from a larger pituitary tumor may include:HeadacheLethargyNasal drainageNausea and vomitingProblems with the sense of smellVisual changesDouble visionDrooping eyelidsVisual field lossRarely, these symptoms may occur suddenly and can be severe.Signs and testsYour health care provider will perform a physical examination. The provider will note any problems with double vision and visual field, such as a loss of peripheral vision or the ability to see in certain areas.Endocrine function tests include:Cortisol levels: Dexamethasone suppression testUrine cortisoltestFollicle-stimulating hormone (FSH) levelsInsulin growth factor-1 (IGF-1) levelsLuteinizing hormone (LH) levelsSerum prolactin levelsTestosterone/estradiol levelsThyroid hormone levels: Free T4 testTSH testTests that help confirm the diagnosis include the following:Formal visual field testingMRI of headTreatmentPituitary tumors are usually not cancerous and therefore won't spread to other areas of the body. However, as they grow, they may place pressure on important nerves and blood vessels.Surgery to remove the tumor is often necessary, especially if the tumor is pressing on the optic nerves, which could cause blindness.Most of the time, pituitary tumors can be removed through the nose and sinuses. However, some tumors cannot be removed this way and will need to be removed through the skull (transcranial).Radiation therapy may be used to shrink the tumor, either in combination with surgery or for people who cannot have surgery.The following medications may shrink certain types of tumors:Bromocriptine or cabergoline are the first-line therapy for tumors that release prolactin. These drugs decrease prolactin levels and shrink the tumor.Ocreotide or pegvisomant is sometimes used for tumors that release growth hormone, especially when surgery is unlikely to result in a cure.Support GroupsThe Pituitary Network Association -- www.pituitary.orgExpectations (prognosis)If the tumor can be surgically removed, the outlook is fair to good, depending upon whether the entire tumor is removed.ComplicationsThe most serious complication is blindness. This can occur if the optic nerve is seriously damaged.The tumor or its removal may cause permanent hormone imbalances. The affected hormones may need to be replaced.Calling your health care providerCall your health care provider if you develop any symptoms of a pituitary tumor.ReferencesMelmed S, Kleinberg D.

Can you list at least 10 problems that might occur if the pituitary gland function were diminished?
The pituitary gland produces, stores, and secretes many hormones. If anything goes wrong with the function of the pituitary, if it is diminished, or increased, drastic body problems can occur. Here are some possibilities: Follicle stimulating hormone - controls estrogen production & egg development Luteinizing hormone - promotes ovulation Adrenocorticotropic hormone - tells the adrenal cortex to release cortisol Thyroid stimulating hormone - tells thyroid to release T3 & T4 which is needed for metabolism Melanocyte-stimulating hormone - stimulates the skin to produce melanin granules Prolactin - tells the mammary glands to produce milk Human growth hormone - responsible for muscle & bone growth Antidiuretic hormone - tells the kidneys to reabsorb H2O, which decreases urine production and helps maintain pH levels and prevent dehydration. Also plays as role in maintaining blood pressure Oxytocin - contributes to milk expression & uterine contractions The potential problems if its function is diminished are too numerous to mention. They could range from mental retardation, general underdevelopment, hypertension, hypotension, dysmenorrhea, amenorrhea, acromegaly, giganitism, cretinism, Cushings disease, Addisons disease, infantile death, problems with delivery...
Can oedema occur in the pituitary gland?
Yes, the pituitary gland can suffer edema.
What happens if there is too little growth hormone?
Somatotropic hormone is another name for growth hormone. If a body does not have enough it will not grow properly. One condition that results from lack of somatotropic hormone is called cretinism. Not only will the body not from properly, but there will likely also be a lack of mental development as well. The gland that is responsible for secreting somatotropic hormone is the anterior lobe of the pituitary.
What problems can you have with a mandible?
There are several pathologies, outside of blunt force injury, that can occur to the mandible. One condition known as TMJ, but more accurately termed TMD, is a musculoskeletal condition that involves the temporomandibular joint and the muscles associated with its function. The other is acromegaly, and that has to do with an overproduction of growth hormone in an adult that makes the jaw grow larger, as well as other parts of their bodies. This condition is caused by a benign tumor that grows on the pituitary gland. And since the pituitary gland is mostly encased in bone, the sella turcica, the pressure caused by the tumor promotes the overproduction of the growth hormone.
Could a human being grow after puberty in anatomical dimensions if adminstered a Pituitary hormone?
No. Once the epiphyseal (growth) plates at the end of your long bones (femur, humerus, etc), have fused (a result of your sex hormone in puberty), you can no longer grow in height (without repeated breaking and moulding of the bones) The pituitary hormone responsible for growth - the Growth Hormone (original), if in excess in a post-pubertal person, will result in acromegaly, a condition where the soft tissue will swell, as does some other bones (notably, your forehead & jaw). If all this was to occur in someone pre-pubertal, it would resort in gigantism - and yes you would continue to grow.
When does an increase in the hormone prolactin occur?
After childbirth
How may malignant skin tumors occur?
Malignant skin tumors may occur in strange, asymmetrical shapes. The tumor may have long finger-like projections that extend across the skin (laterally) or down into the skin.
Which hormone is absolutely necessary for ovulation to occur?
Estrogen
Which hormone does ovulation occur after its burstlike release?
LH
How many intracranial tumors occur per year?
The incidence of primary intracranial tumors is 11.5 per 100,000, or approximately 35,000 persons per year
