The tumor causes the gland to produce too much growth hormone. This, in turn, stimulates the liver to produce too much IGF-1, which causes the excess tissue growth.

The pituitary gland is a small gland located behind the nasal sinuses and above the roof of the mouth at the base of the skull. It is connected to the hypothalamus, a part of the brain. Together, the two control the production of many of the important hormones in the body. The pituitary gland sits in a tight bony space and has little room to grow or expand when swollen or if there is a tumor.

CDI itself does not interfere with menstruation or fertility. However, it may be associated with these or other problems if the disease or injury that caused the DI also damages adjacent parts of the brain or pituitary where other hormones are normally produced. Head trauma is one of the things that can cause this kind of collateral damage, but it does not always do so. Therefore, each patient with CDI must be evaluated separately to determine if any of the other hormones have been affected.

A pituitary tumor is an abnormal growth of pituitary cells. Pituitary tumors can either be nonfunctional (that is they do not secrete hormones) or produce specific hormones, such as prolactin (causing infertility, decreased libido, and osteoporosis), growth hormone (causing acromegaly), ACTH (causing Cushing's), TSH (causing hypothyroidism), or be nonfunctional (that is they do not produce hormones).

This depends on the type of tumor and the size of the tumor. A large tumor may cause loss of vision, particularly peripheral vision, if it compresses the optic chiasm (where the optic [eye] nerves converge). Headache may also occur; the type of headache varies from patient to patient. Headache may occur with a large or a small tumor.

Microadenomas do not cause CDI. However, infiltrative diseases of the pituitary, which can mimic micros on MRI, can. Given your symptoms, you should have tests to determine whether you do, indeed, have CDI.

No, the average rosacea sufferer has normal sebaceous glands (both in structure and activity). Numerous clinical studies have demonstrated that true rosacea does not involve the facial sebaceous glands. Please note that there is one exception to this rule -- rosacea sufferers who develop rhinophyma (the bulbous red nose). After years of flushing, rhinophyma sufferers may experience inflammation and growth of the sebaceous glands around the nose.

The pituitary, or master gland, controls the function of many other glands - the thyroid, adrenals, ovaries, testes. It also produces growth hormone and anti-diuretic (water saving) hormone.

The pituitary gland is NOT in the brain and pituitary tissue is different from brain tissue. Since the pituitary gland is located at the base of the brain and is connected to the brain by a thin stalk, there is often confusion, particularly by insurance companies, about the classification of a pituitary tumor. A pituitary tumor is NOT a brain tumor.

In some patients with CDI, the pituitary is able to produce small amounts of the hormone as, for example, when they smoke or become dehydrated. However, the variability in the duration of action of the dDAVP in you is probably due mainly to variability in the efficiency of adsorption. Colds, sinusitis, or even a little hay fever markedly impair the absorption of the drug from the nasal mucosa and result in much shorter durations of action.

The prostate gland is located at the base or outlet of the bladder. One function of the prostate gland is to help control urination by pressing directly against the part of the urethra that it surrounds. Another function of the prostate gland is to produce some of the substances that are found in normal semen, such as minerals and sugar.

The prostate gland is known as a secondary reproductive organ. The gland produces fluids which contain enzymes and other substances which assist the sperm in fertilization. One third of the ejaculate fluid is produced by the prostate itself and the remaining two thirds is produced by the seminal vesicles or ejaculatory ducts.

When CDI (the type that is associated with absence of the pituitary bright spot and is treated with dDAVP nasal spray) begins in infancy or early childhood, it is often genetic. If so, one parent or other relative may or may not have CDI also. In any case a genetic analysis should be performed on the child unless, of course, some other cause such as a congenital malformation of the brain or a tumor has already been identified.

Is there other treatment or medication? I was told that Tegretol is used to treat seizure disorder and CDI. Yes, there are other medications that work quite well in CDI. One is Tegretol. Another is chlorpropamide. Both can be taken by mouth and may have side effects but they are usually not serious. CDI may result in increased loss of water from skin or lungs (so called insensible loss) but it does not manifest as an appreciable increase in perspiration.

Prolactin-producing tumors are most successfully treated with medical therapy (pills). In over 90% of patients, medical therapy reduces tumor size and blood prolactin levels. In approximately 8-10% of patients, medical treatment is not completely effective and surgery may be necessary.

Pituitary tumors are common. In autopsy studies of patients who did not have known pituitary disease, as many as 26% had a small tumor (adenoma) in the gland. Molecular biology studies have shown that a change in the DNA of pituitary cells can cause unregulated growth of a particular cell type resulting in a pituitary tumor, called an adenoma. There are no known environmental causes. Very uncommonly, pituitary tumors may be inherited.

No, in over 99% of patients, this is NOT a cancer; it is benign. Although the tumor is benign, it can cause problems because of its size, because it causes the normal pituitary gland to become underactive (hypopituitarism) or because of excessive hormone production by the tumor.

No although the tumor may be in the area of the pituitary. A craniopharyngioma arises from abnormal development of the pituitary gland during fetal (in the womb) development. It may be located within the pituitary gland or above the pituitary gland. This is a tumor that one is born with and may enlarge at any time even in people over 60 years of age. It is not a cancer although some tumors can grow quickly and may return after surgery.

Diseases of the thyroid gland are very common, affecting millions of people. The most common diseases are an over- or under-active gland. These conditions are called hyperthyroidism (e.g., Grave's disease) and hypothyroidism. Sometimes the thyroid gland can become enlarged from over-activity (as in Grave's disease) or from under-activity (as in hypothyroidism). An enlarged thyroid gland is often called a "goiter.

Patients will get a new cyst / nodule / tumor if Doctor just removed the existing cyst / nodule / tumor. The reason is the ROOT of cyst / nodule / tumor still there. It can't be removed by operation. This is why some patients need to get 2nd operation or 3rd operation. So some Doctors may suggest patients to remove all of their thyroid tissues. To remove whole thyroid gland can avoid get other cyst / nodule / tumor but it is absolutely wrong.

Diseases of the thyroid gland are common in dogs and cats (humans, too). Dogs with thyroid disease are more commonly hypothyroid (underactive gland) and cats with thyroid disease are more commonly hyperthyroid (overactive gland). This article discusses thyroid anatomy, common conditions and treatment options for dogs and cats with thyroid disease.
