Who is at risk for gigantism?
Middle-aged individuals are at a higher risk of developing acromegaly than those in other age groups. The most specific reason for the existence of this risk factor is that any form of increased growth hormone production in the body that occurs in an individual who is seventeen years old or younger is referred to as a different disease called gigantism.
What causes pituitary gigantism?
Gigantism is a serious condition that is nearly always caused by an adenoma, a tumor of the pituitary gland. Gigantism occurs in patients who had excessive growth hormone in childhood. The pituitary tumor cells secrete too much growth hormone (GH), leading to many changes in the body.

How do you know if you have gigantism?
How is gigantism diagnosed? If gigantism is suspected, the diagnosis is usually confirmed by taking blood tests to measure the levels of growth hormone and insulin-like growth factor 1 (IGF1) circulating in the blood. IGF1 is released into the blood primarily by the liver in response to growth hormone.
What does gigantism do to the body?
Gigantism is a rare condition that causes abnormal growth in children. This change is most notable in terms of height, but girth is affected as well. It occurs when your child's pituitary gland makes too much growth hormone, which is also known as somatotropin.

How do you distinguish between gigantism and acromegaly?
When you have too much growth hormone, your bones increase in size. In childhood, this leads to increased height and is called gigantism. But in adulthood, a change in height doesn't occur. Instead, the increase in bone size is limited to the bones of your hands, feet and face, and is called acromegaly.
How fast do pituitary tumors grow?
How fast do pituitary tumors grow? Most pituitary tumors are slow growing, approximately 1-3mm/year.
What is the most common cause for the overproduction of growth hormone in gigantism?
The most common cause of too much GH release is a noncancerous (benign) tumor of the pituitary gland. Other causes include: Genetic disease that affects the skin color (pigmentation) and causes benign tumors of the skin, heart, and endocrine (hormone) system (Carney complex)
What is gigantism caused by?
a form of gigantism caused by hypersecretion of pituitary growth hormone; a rare disorder commonly the result of a pituitary adenoma.
What is cerebral gigantism?
cerebral gigantismgigantism in the absence of increased levels of growth hormone, attributed to a cerebral defect; infants are large, and accelerated growth continues for the first 4 or 5 years, the rate being normal thereafter. The hands and feet are large, the head is large, narrow and long, and the eyes have an antimongoloid slant with an abnormally wide space between them. The child is clumsy, and mental retardation of varying degree is usually present. Called also Sotos syndrome.
What is the term for the oversecretion of growth hormone by the pituitary gland?
pituitary gigantismthat caused by oversecretion of growth hormone by the pituitary gland; see gigantism. Called also Launois syndrome.
What causes gigantism in the pituitary gland?
A pituitary gland tumor is almost always the cause of gigantism. The pea-sized pituitary gland is located at the base of your brain. It makes hormones that control many functions in your body. Some tasks managed by the gland include: 1 temperature control 2 sexual development 3 growth 4 metabolism 5 urine production

What is pituitary gigantism?
Pituitary gigantism is a rare but very important subgroup of patients with excessive height, as it has an identifiable and clinically treatable cause . The disease is caused by chronic growth hormone and insulin-like growth factor 1 secretion from a pituitary somatotrope adenoma that forms before the closure of the epiphyses.
Why is early diagnosis important for pituitary gigantism?
Early diagnosis and rapid referral for effective therapy appear to improve outcomes in patients with pituitary gigantism; therefore, a high level of clinical suspicion and efficient use of diagnostic resources is key to controlling overgrowth and preventing patients from reaching very elevated final adult heights.
