A dwarf is an extremely short adult who is less than 58 inches tall. The word midget is considered derogatory and offensive. Both words describe a short person, but refer to different physical characteristics and genetic conditions. The term midget is now rarely used and is considered offensive. But its usage was very common until the end of the twentieth century. It has given way to "short person" or "little person".
Dwarfism is short stature that results from a genetic or medical condition. Dwarfism is generally defined as an adult height of 4 feet 10 inches centimeters or less. The average adult height among people with dwarfism is 4 feet cm. Many different medical conditions cause dwarfism.
The most common type of dwarfism is achondroplasia pronounced: ay-kon-dreh-PLAY-zyuh. Most types of dwarfism are caused by a genetic change mutation in an egg or sperm cell that happens before the start of pregnancy conception. Others happen because of a genetic change s inherited from one or both parents. Genetic changes happen randomly. There is nothing a parent could do before or during pregnancy to prevent this change from happening.
Dwarfism is a medical or genetic condition that usually results in an adult height of 4'10" or shorter, among both men and women, although in some cases a person with a dwarfing condition may be slightly taller than that. The most frequently diagnosed cause of short stature is achondroplasia, a genetic condition that results in disproportionately short arms and legs. The average height of adults with achondroplasia is 4'0". Other relatively common genetic conditions that result in disproportionate short stature include spondyloepiphyseal dysplasia congenita SEDc , diastrophic dysplasia, pseudoachondroplasia, hypochondroplasia, and osteogenesis imperfecta OI.
