What is Hyperfunction of pituitary gland?

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.

What is the effect of hypersecretion of pituitary gland?

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.

What is the common cause of hyperpituitarism?

Most cases of hyperpituitarism (overactive pituitary gland) are caused by a pituitary tumor. No one knows what causes these tumors but possible culprits include: Benign tumors are the most frequent cause of an overactive pituitary gland.

What does hyperpituitarism mean?

Hyperpituitarism is defined as an excessive secretion or production of one or more of the hormones produced by the pituitary gland. In this article, we present an overview of the diagnosis and management of secretory tumors of the pituitary gland.

What are the effects of hypersecretion?

GH hypersecretion results in gigantism or acromegaly, a condition associated with significant morbidity and mortality, while GH deficiency results in growth retardation in children and the GH deficiency syndrome in adults.

Which of the following disorders is caused due to Hyposecretion of hormone?

Hence, cretinism and goitre are caused by hyper or hyposecretion of thyroxine.

What is hyperpituitarism?

How is hyperpituitarism diagnosed?

Hyperpituitarism, or primary hypersecretion of pituitary hormones, is rare in children. It typically results from a pituitary microadenoma. If laboratory findings suggest pituitary hormone excess, the presence of a pituitary adenoma should be confirmed with magnetic resonance imaging (MRI).

What problems can the pituitary gland cause?

Pituitary disorders

  • Change hormone production, leading to symptoms such as weight gain, stunted or excessive growth, high blood pressure, low sex drive or mood changes.
  • Press against the pituitary gland, optic nerves or brain tissue, causing vision problems or headaches.

What conditions result when the pituitary gland hypersecretion growth hormone?

What are the symptoms and effects of hypersecretion or Hyposecretion?

breathing rate are increased , while digestive processes are decreased. [No known effects are due to hyposecretion of these, but hypersecretion can caused hypertension, increased blood glucose level , and high heart rate].
