Gigantism, also known as giantism (from Greek gigas, gigantas "giant"), is a condition characterized by excessive growth and height significantly above average.[1]

Contents

Types

As a medical term, gigantism can refer to:

  • "Pituitary gigantism",these are people who their hormones over produce which is due to prepubertal growth hormone excess. This is sometimes equated with acromegaly, but more precisely, an excess of growth hormone leads to "pituitary gigantism" (vertical growth) if the epiphyseal plates have not yet closed,[2] but it leads to "acromegaly" (lateral growth) if they have closed.

Terminology

The term is typically applied to those whose height is not just in the upper 1% of the population but several standard deviations above mean for persons of the same sex, age, and ethnic ancestry. The term is seldom applied to those who are simply "tall" or "above average" whose heights appear to be the healthy result of normal genetics and nutrition.

Other names somewhat obsolete for this pathology are hypersomia (Greek: hyper over the normal level; soma body) and somatomegaly (Greek; soma body, object pronoun somatos of the body; megas, megalos great).

Many of those who have been identified with gigantism have suffered from multiple health problems involving their circulatory or skeletal system.
