Introduction. Pituitary hyperfunction usually involves hypersecretion of a single pituitary hormone. The three common examples of pituitary hypersecretion involve growth hormone, ACTH, and prolactin, resulting in the clinical syndromes of acromegaly, Cushing’s disease, and galactorrhea, respectively.
Which is a Hyperpituitary disorder of the anterior lobe of the pituitary gland?
Pituitary Gland : Hyperpituitarism (Overactive Pituitary Gland) Having an overactive pituitary gland is called hyperpituitarism. It is most commonly caused by noncancerous tumors. This causes the gland to secrete too much of certain kinds of hormones related to growth, reproduction, and metabolism, among other things.
What are the disorders of the anterior pituitary gland?
Table II.
| Hormone | Overproduction |
|---|---|
| Growth hormone | Acromegaly (gigantism) |
| ACTH | Cushing’s disease |
| TSH | Hyperthyroidism |
| LH and FSH | Polycystic ovary syndrome, precocious puberty |
What does Hyposecretion of pituitary gland causes?
Overproduction or underproduction of a pituitary hormone will affect the respective end-organ. 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.
How do you treat Hyperpituitarism?
Treatment options
- Medication. If a tumor is causing your hyperpituitarism then medication may be used to shrink it.
- Surgery. Surgery is performed to remove a tumor from the pituitary gland.
- Radiation. Radiation is another option if you’re unable to have surgery to remove the tumor.
What are symptoms of hyperpituitarism?
| Hyperpituitarism | |
|---|---|
| Symptoms | Hirsutism |
| Causes | From a pituitary microadenoma. |
| Diagnostic method | MRI |
| Treatment | Dopamine agonists |
What are pituitary disorders?
Pituitary disorders occur when the pituitary gland makes too much or too little of a particular hormone. Most often, these disorders are caused by a pituitary tumor. Most pituitary tumors are noncancerous (benign).
What does the anterior pituitary gland release?
The anterior pituitary gland produces six major hormones: (1) prolactin (PRL), (2) growth hormone (GH), (3) adrenocorticotropic hormone (ACTH), (4) luteinizing hormone (LH), (5) follicle-stimulating hormone (FSH), and (6) thyroid-stimulating hormone (TSH) (Table 401e-1).
What causes hypersecretion?
Hypersecretion. Hypersecretion by an endocrine gland is often caused by a tumor. For example, a tumor of the pituitary gland can cause hypersecretion of growth hormone. If this occurs in childhood and goes untreated, it results in very long arms and legs and abnormally tall stature by adulthood (see ).
Who discovered Hyperpituitarism?
Harvey Cushing also introduced the terminologies ‘hyperpituitarism’ and ‘hypopituitarism’ and described some of their clinical features, including acromegaly, as well as the potential role of (neuro)surgery in these cases [54].
