Acromegaly is a hormonal disorder that results from excess growth hormone (GH) in the body, typically caused by a pituitary adenoma. It leads to abnormal enlargement of bones and tissues, particularly noticeable in the hands, feet, and face.
congrats on reading the definition of acromegaly. now let's actually learn it.
Acromegaly is most commonly caused by a benign tumor on the pituitary gland known as a pituitary adenoma.
Excessive growth hormone secretion in acromegaly can lead to complications such as diabetes mellitus, hypertension, and cardiovascular disease.
Somatostatin analogs like octreotide are commonly used to manage acromegaly by inhibiting GH release.
Diagnostic evaluation for acromegaly often includes measuring levels of insulin-like growth factor 1 (IGF-1) and conducting an oral glucose tolerance test (OGTT).
Surgical removal of the pituitary tumor is often considered the first line of treatment for acromegaly.
