Acromegaly or gigantism is a rare hormonal disorder than can develop when your pituitary gland overproduces the growth hormone. Most of the time this overproduction of the growth hormone is caused by a tumor. The excess growth hormone causes swelling, thickening of the skin, tissue growth and enlargement of the bones, especially in the hands, feet and face.

The overproduction of the growth hormone in children can lead to a condition known as gigantism. This may lead to an abnormal increase in the height and bone growth. Overproduction of the growth hormone in middle aged adults causes acromegaly.

The treatment of choice in pituitary tumors is surgery. When surgery cannot be performed or if the entire tumor cannot be removed, then the treatment of choice is medications.

Somatostatin analogues (SSA) are synthetic versions of the hormone in the brain somatostatin. Two SSA's are octreotide (Sandostatin, Sandostatin LAR) and lanreotide (Somatuline Depot). Somatostatin is a hormone that inhibits the release of the growth hormone. SSA's can decrease the growth hormone levels by blocking the excess production in the pituitary gland. Common side effects are pain at the injection site, intestinal cramping, diarrhea and gallbladder problems.

Growth hormone receptor antagonists (GHRAs). The medication pegvisomant (Somavert) blocks the effect of growth hormone on the body tissues. It is administered daily by a subcutaneous injection. This medication can normalize growth hormone levels and

Not to mention, the thyroid is regulated by the thyroid-stimulating hormone, which is also released by the anterior pituitary gland.…

    5-alpha reductase inhibitors. The medications in this category shrink prostate by preventing hormonal changes that cause prostate growth. The mechanism of action is that 5-alpha reductase inhibitor medication blocks the conversion of testosterone to DHT resulting in lower intraprostatic levels of DHT. This process causes change in epithelial cell of the transition zone. This process leads to inhibition of prostatic growth, involution, and apoptosis. Eventually, prostate volume and progression of disease will be decreased. Thus, patients with larger prostates may achieve a greater benefit. However, maximal reduction in prostate volume requires 6 months of therapy. These medications include Finasteride (Proscar) and Dutasteride. Side effects…

This satisfaction of doing well the athletes feel tend to overpower their minds and make them want to become even better. This results in, the usage and over usage of HGH.

These drugs have serious side effects that are hard to get rid of, such as, liver failure, neurological issues, and HIV. The athletes who have knowledge on what can potentially happen to them just flies right over their head, and they continue to cheat at the sports they get paid to play.

    There are several potential causes of achondroplasia. The first is a genetic mutation on chromosome 4 of the fibroblast growth factor receptor 3 (FGFR3). Scientists do not know why this mutation occurs. The disorder can also be passed on from an affected parent. If one parent has the disorder they have a 50% chance of having an affected child. If both parents have the disorder they have a 50% chance of having an affected child, a 25% chance of having a normal child, and a 25% chance that they will have a child that inherits one abnormal gene from each parent resulting in severe skeletal abnormalities that lead to early death for that child.
