Acromegaly is a disorder that results in excess growth of certain parts of the human body. It is caused by excess growth hormone (GH) after the growth plates have closed. The initial symptom is typically enlargement of the hands and feet. [ 3 ]
Hypersecretion of glucagon, somatostatin, chromogranin, or calcitonin, ectopic secretion of ACTH resulting in Cushing's syndrome, and hypersecretion of somatotropin–releasing hormone (causing acromegaly) sometimes occur in non–β-cell tumors. All of these are rare in MEN 1.
In some cases low levels of other pituitary hormones are secreted. Rarely a cat may have double adenomas. In a few cases the diagnosis has been pituitary acidophilic hyperplasia. In dogs nearly all cases of acromegaly are caused by endogenous or exogenous progestogens, this causes a hypersecretion of growth hormones from the mammary gland ...
Hyperpituitarism is a condition due to the primary hypersecretion of pituitary hormones; [3] [medical citation needed] it typically results from a pituitary adenoma.In children with hyperpituitarism, disruption of growth regulation is rare, either because of hormone hypersecretion or because of manifestations caused by local compression of the adenoma.
Diagnosis involves blood tests to measure growth hormone levels. [2] Treatment is by growth hormone replacement using synthetic human growth hormone. [1] The frequency of the condition is unclear. [2] Most cases are initially noticed in children. [1] The genetic forms of this disease are estimated to affect about 1 in 7,000 people. [3]
Acromegaly is a syndrome caused by the anterior pituitary gland producing excess growth hormone (GH). [42] A number of disorders may increase the pituitary's GH output, although most commonly it involves a tumor called pituitary adenoma , derived from a distinct type of cell ( somatotrophs ).
The diagnosis is achieved with magnetic resonance imaging and blood tests. Treatment is by the timely correction of hormone deficiencies. In many cases, surgical decompression is required. Many people who have had a pituitary apoplexy develop pituitary hormone deficiencies and require long-term hormone supplementation. The first case of the ...
With respect to diagnosis, their guidelines state that "adults patients with structural hypothalamic/pituitary disease, surgery or irradiation in these areas, head trauma, or evidence of other pituitary hormone deficiencies be considered for evaluation for acquired GHd" and that "idiopathic GHd in adults is very rare, and stringent criteria are ...
