Acromegaly Sentence Examples
Acromegaly results when hGH is over-produced after the onset of puberty.
In acromegaly, the pituitary continues to release GH and ignores signals from the hypothalamus.
Somatostatin analogs, given as injections, are successful in treating acromegaly by inhibiting the release of GH.
In adults, too much GH causes a condition called acromegaly, but deficiency in adults had been considered previously to have no importance.
The somatotropin test also aids in documenting the excess hGH production responsible for gigantism or acromegaly, and confirms underactivity or overproduction of the pituitary gland (hypopituitarism or hyperpituitarism, respectively).Advertisement
The somatomedin C test is usually ordered to help detect pituitary abnormalities, hGH deficiency, and acromegaly.
This procedure, also called the glucose loading test, is performed to evaluate excessive baseline levels of hGH and to confirm diagnosis of gigantism in children (and acromegaly in adults).
In a child with excessive hGH levels, failure of suppression indicates anterior pituitary dysfunction and confirms a diagnosis of gigantism (or acromegaly).
If such a tumor develops within the first ten years of life, the result is gigantism (in which growth is accelerated) and not acromegaly.
If the tumor develops after growth has stopped, the result is acromegaly, not gigantism.Advertisement
Acromegaly is a disease in which an abnormality in the pituitary gland leads to an oversecretion of growth hormone.
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.
In children whose bony growth plates have not closed, the chemical changes of acromegaly result in exceptional growth of long bones.
When the abnormality occurs after bone growth stops, i.e. in adults, the disorder is called acromegaly.
Acromegaly is a relatively rare disorder, occurring in approximately 50 out of every 1 million people.Advertisement
The cause of acromegaly can be traced to the pituitary's production of GH.
The most common cause of acromegaly and gigantism is the development of a noncancerous tumor within the pituitary, called a pituitary adenoma.
In rare cases, acromegaly is caused by the abnormal production of GHRH, which leads to the increased production of GH.
In acromegaly, an individual's hands and feet begin to grow, becoming thick and doughy.
People with acromegaly have more skin tags, or outgrowths of tissue, than normal.Advertisement
Patients with acromegaly often suffer from headaches and arthritis.
Because acromegaly produces slow changes, diagnosis is often significantly delayed.
Because the quantity of GH produced varies widely under normal conditions, demonstrating high levels of GH in the blood is not sufficient to merit a diagnosis of acromegaly.
Patients with acromegaly will not show this decrease and will often show an increase in GH production.
The first step in treatment of acromegaly is removal of all or part of the pituitary adenoma.Advertisement

The enormously long teeth sometimes found in rodents also are not due to hypertrophy, as they are normally endowed with rapid growth to compensate for the constant and rapid attrition which takes place from the opposed teeth.
Overproduction of hGH or IGH-I, or an exaggerated response to these hormones, can lead to gigantism or acromegaly, both of which are characterized by a very large stature.
