In some cases the condition can be passed on genetically through a mutated gene.Other names somewhat obsolete for this pathology are hypersoma (Greek: hyper over the normal level; soma body) and somatomegaly (Greek; soma body, genitive somatos  of the body; megas, gen. megalou great). In the past, while many of them were social outcasts because of their height, some (usually unintentionally) found employment in Friedrich Wilhelm Is famous Potsdam Giants regiment. Many of those who have been identified with gigantism have had multiple health problems involving the circulatory or skeletal system, as the strain of maintaining a large, heavy body places abnormal demands on both the bones and the heart. Society and culture
Reports of gigantism exist throughout history, with some nations and tribes taller than others. The giants of Crete are listed in various historic sources, beginning with Titan, a Greek mythological giant, and including Gigantus, after whom giants and gigantism are named. Rhodes is another island where giants were said to have lived, with the Colossus of Rhodes, a giant statue of a giant patron god Helios. Goliath, a giant mentioned in the Bible, was a Philistine warrior who was killed by David in the war between the Israelites and the Philistines. See also

Gigantism (Greek: γίγας, gígas, "giant", plural γίγαντες, gígantes), also known as giantism, is a condition characterized by excessive growth and height significantly above average. In humans, this condition is caused by over-production of growth hormone in childhood, resulting in people 2.4 to 2.7 m (8.0 to 9.0 ft) in height.It is a rare disorder resulting from increased levels of growth hormone before the fusion of the growth plate which usually occurs at some point soon after puberty. This increase is most often due to abnormal tumor growths on the pituitary gland. Gigantism should not be confused with acromegaly, the adult form of the disorder, characterized by somatic enlargement specifically in the extremities and face. Cause
Gigantism is characterized by an excess of growth hormone (GH). The excess of growth hormone that brings about gigantism is virtually always caused by pituitary growths (adenomas). These adenomas are on the anterior pituitary gland. They can also cause overproduction of GHs hypothalamic precursor known as growth hormone releasing hormone (GHRH).As a result of the excessive amounts of growth hormone, children achieve heights that are well above normal ranges. The specific age of onset for gigantism varies between patients and gender, but the common age that excessive growth symptoms start to appear has been found to be around 13 years. Other health complications, such as hypertension, may occur in pediatric patients with hyper-secretion of growth hormone.
