  Acromegaly - Wikipedia, the free encyclopedia
In over 90 percent of acromegaly patients, the overproduction of GH is caused by a benign tumor of the pituitary gland, called an adenoma.
In a few patients, acromegaly is caused not by pituitary tumors but by tumors of the pancreas, lungs, and adrenal glands.
If acromegaly is suspected, medical imaging and medical laboratory investigations are generally used together to confirm or rule out the presence of this condition.

 Acromegaly Information on Healthline
However, in acromegaly, there is an increased amount of HGH released, generally by a tumor that forms in the pituitary.
Familial acromegaly is transmitted in an autosomal dominant pattern- which means that it has an equal chance of affecting both boys and girls in a single family.
Most cases of acromegaly are detected on an initial visit to a family physician, although some early or mild cases may be missed, causing a delay in the diagnosis.

 acromegaly.org - About Acromegaly
Acromegaly is a serious systemic condition caused in over 98% of cases by an adenoma (i.e., benign tumor) of the pituitary gland that secretes excessive growth hormone (GH).
The diagnosis of acromegaly is confirmed by demonstrating elevated levels of both GH and insulin-like growth factor-1 (IGF-1).
Following the biochemical confirmation of acromegaly, a MRI of the pituitary should be performed to confirm the presence of a pituitary adenoma.

 Acromegaly
Acromegaly is the Greek word for "extremities" and "enlargement." When the pituitary gland produces excess growth hormones, this results in excessive growth - called acromegaly.

 Novartis Oncology - What is Acromegaly?
Acromegaly is an insidious disease in adults caused by excessive secretion of growth hormone (GH), a key factor in body growth and organ development.
Acromegaly can also result in complications including cardiovascular disease; carbohydrate intolerance (which can lead to diabetes); respiratory distress, such as upper airway obstruction and sleep apnea; and secondary malignancies, such as colon cancer.

 Acromegaly and gigantism
Acromegaly is a disorder in which the abnormal release of a particular chemical from the pituitary gland in the brain causes increased growth in bone and soft tissue, as well as a variety of other disturbances throughout the body.
Acromegaly is a relatively rare disorder, occurring in approximately 50 out of every one million people (50/1,000,000).
In acromegaly, the pituitary continues to release GH and ignores signals from the hypothalamus.

Acromegaly is the clinical syndrome that results from prolonged, excessive secretion of growth hormone (GH).
Acromegaly can lead to serious illness and even death if it is not treated successfully, but treatment that lowers growth hormone to normal leads to a normal life span.
Acromegaly may be associated with an increased risk of benign and malignant tumors if growth hormone levels are left uncontrolled.

 OHSU Pituitary Unit - Acromegaly
Although serum GH is elevated in most patients with acromegaly, measuring a random serum GH level is not a reliable way to diagnose the disease since GH release is pulsatile and levels fluctuate even in normal individuals.
Patients with acromegaly also have an increased risk of developing colonic polyps (with a presumed increased risk of colon cancer) so those individuals typically receive a screening colonoscopy and are closely followed thereafter.
Finally, patients with acromegaly are at increased risk of developing carpal tunnel syndrome that is characterized by wrist pain and finger numbness.

 Acromegaly
Acromegaly is a serious condition that occurs when the body produces too much of the hormones that control growth.

 Acromegaly and Acromegaly Symptoms and Sandostatin
Acromegaly is a rare disease that affects about 40-60 out of every million people in the U.S. It is caused by the uncontrolled hypersecretion of growth hormone (GH) in the pituitary, a tiny gland — about the size of a pea — located behind the eyes, just below the brain.
While acromegaly itself is usually not fatal, the complications (such as cardiomegaly or diabetes) can be life threatening.
While surgery is considered first-line therapy for most patients, it is not indicated for everyone, and its effectiveness as a cure depends on factors such as the size of the pituitary tumor, invasiveness of the tumor, and the skill of the surgeon.
