Radiation therapy can be offered as an outpatient if surgery has not provided a complete cure. Radiation therapy may not only reduce growth hormone and IGF1 levels but can also be effective in controlling tumour growth. The main types of drugs available to reduce growth hormone levels may lower growth hormone levels, block growth hormone action and possibly reduce the size of the tumour.
Hypopituitarism is treated by replacing those hormones that are low, for example hydrocortisone ' or thyroid hormone tablets see the article on hypopituitarism for further details. Radiation therapy to the pituitary gland can also cause hypopituitarism. Dopamine-based drugs can cause reduced appetite, nausea, vomiting and dizziness. Somatostatin analogues are given by injection and can cause skin and muscle irritation at the site of the injection.
These drugs can also cause tummy upset most commonly diarrhoea and cramping abdominal pain shortly after injections. Pegvisomant can disturb the liver function and regular blood tests are used to monitor this. Following the diagnosis of gigantism, regular, long-term follow up by an endocrinologist is needed to monitor hormone levels both growth hormone and IGF1. This helps to detect any tumour growth and screening for complications that might have occurred. Some of the long term complications that some people might experience relate to the excessive height and overall effects on soft tissues and internal organs.
For example:. About Contact Events News. Search Search. You and Your Hormones. The standard treatment for someone who has a pituitary tumor is to remove it through endonasal surgery [in which surgeons go through the nose to cut out the tumor].
The goal is remove all the adenoma to protect the normal pituitary gland. The other treatment options for someone with acromegaly or gigantism, as she had, is radiotherapy --radiosurgery or stereotactic radiotherapy—that is, giving focused radiation to the pituitary tumor to avoid damage to surrounding structures. Then the third are medications that block the effects of growth hormone or block the actions of insulin growth factor 1.
That's what's called the "second messenger of growth hormone. For people with acromegaly, aside from the gigantism, are there other frequent health defects? The problem with acromegaly is really quite severe.
It's a benign adenoma So people with untreated acromegaly gigantism, in addition to the growth problems, they can have premature death because of the other associated problems.
They get organomegaly--so all their organs get big, too--so they have a higher incidence of heart disease. Then you couple that with hypertension and diabetes and you can imagine they don't live very long. Is that on the high end? Most people who get a growth hormone secreting adenoma are adults. Children or adolescents that get a growth hormone-secreting tumor develop gigantism, in addition to the other problems associated with the excess growth hormone, because their bones have not stopped growing.
So, if you take your average adult who gets acromegaly--and say he has sleep apnea and hypertension and diabetes, if it's caught early enough, between three and five years, usually the hypertension and diabetes become easier to control. They found that individuals affected by the condition known as the X-LAG syndrome, carry a microduplication of 4 genes including the GPR gene on the X chromosome. How would you answer a child if they asked you this question?
He measured 2m Closer to home, Julius Koch alias Constantin the giant lived in Mons from to and measured 2m59 while a man currently living in France has grown to a height of 2m Gigantism is characterised by excessive growth. They may be used with octreotide. Octreotide is a synthetic hormone that, when injected, can also lower the levels of growth hormones and IGF In situations where these drugs are not helpful, daily shots of pegvisomant might be used as well.
Pegvisomant is a drug that blocks the effects of growth hormones. This dose is enough to destroy the tumor. Gamma knife treatment takes months to years to be fully effective and to return the levels of growth hormone to normal. According to St.
