Muchas afecciones diferentes causan enanismo. Por eso, es importante ser consciente de la preferencia de alguien que tiene este trastorno. Casi todas las personas con enanismo desproporcionado tienen capacidades intelectuales normales.
Por lo general, este trastorno ocasiona lo siguiente:. Algunos signos son los siguientes:. El enanismo proporcionado surge de las afecciones presentes en el nacimiento o que aparecen en la primera infancia y limitan el crecimiento y el desarrollo en general. La deficiencia de la hormona del crecimiento es una causa relativamente frecuente del enanismo proporcionado.
Algunos signos comprenden los siguientes:. Es posible que el enanismo proporcionado no sea evidente de inmediato. Most people with dwarfism have disorders that cause disproportionately short stature. Usually, this means that a person has an average-size trunk and very short limbs, but some people may have a very short trunk and shortened but disproportionately large limbs. In these disorders, the head is disproportionately large compared with the body.
Almost all people with disproportionate dwarfism have normal intellectual capacities. Rare exceptions are usually the result of a secondary factor, such as excess fluid around the brain hydrocephalus.
The most common cause of dwarfism is a disorder called achondroplasia, which causes disproportionately short stature. This disorder usually results in the following:.
Another cause of disproportionate dwarfism is a rare disorder called spondyloepiphyseal dysplasia congenita SEDC. Proportionate dwarfism results from medical conditions present at birth or appearing in early childhood that limit overall growth and development.
So the head, trunk and limbs are all small, but they’re proportionate to each other. Because these disorders affect overall growth, many of them result in poor development of one or more body systems. Growth hormone deficiency is a relatively common cause of proportionate dwarfism.
It occurs when the pituitary gland fails to produce an adequate supply of growth hormone, which is essential for normal childhood growth. Signs and symptoms of disproportionate dwarfism are often present at birth or in early infancy. Proportionate dwarfism may not be immediately apparent.
See your child’s doctor if you have any concerns about your child’s growth or overall development. Quienes tienen acondroplasia y padres pituitaro peso promedio reciben una copia mutada del gen asociado con el trastorno y una copia normal del gen. Una persona con el trastorno puede pasarles a sus hijos tanto la copia mutada como la copia normal. A veces, se desconoce la causa. About 80 percent of people with achondroplasia are born to parents of average height.
A person with achondroplasia and with two average-size parents received one mutated copy of the gene associated with the disorder and one normal copy of the gene.
A person with the disorder may pass along either a mutated or normal copy to his or her own children. Turner syndrome, a condition that affects only girls and women, results when a sex chromosome the X chromosome is missing or partially missing.
A female inherits an X chromosome from each parent. A girl with Turner syndrome has only one fully functioning copy of the female sex chromosome rather than two. The cause of growth hormone deficiency can sometimes be traced to a genetic mutation or injury, but for most people with the enanisno, no cause can be identified. Other causes of dwarfism include other genetic disorders, deficiencies in other hormones or poor nutrition.

Sometimes the cause is unknown. Las complicaciones de los trastornos relacionados con el enanismo pueden variar, pero algunas complicaciones son frecuentes para una cantidad de enfermedades. Las mujeres con enanismo desproporcionado pueden tener problemas respiratorios durante el embarazo. Las personas de estatura promedio pueden tener conceptos errados acerca de las personas con enanismo.
The characteristic features of the skull, spine and limbs shared by most forms of disproportionate dwarfism result in some common problems:. With proportionate dwarfism, problems in growth and development often result in complications with poorly developed organs. For example, heart problems that often occur with Turner syndrome can have a significant effect on health. An absence of sexual maturation associated with growth hormone deficiency or Turner syndrome affects both physical development and social functioning.
Women with disproportionate dwarfism may develop respiratory problems during pregnancy. A C-section cesarean delivery is almost always necessary because the size and shape of the pelvis doesn’t allow for successful vaginal delivery. Most people with dwarfism prefer not to be labeled by a condition. However, some people may refer to themselves as dwarfs, little people or people of short stature.
The word “midget” is generally considered an offensive term. People of average height may have misconceptions about people with dwarfism. And the portrayal of people with dwarfism in modern movies often includes stereotypes. Misconceptions can impact a person’s self-esteem and limit opportunities for success in school or employment. Children with dwarfism are particularly vulnerable to teasing and ridicule from classmates. Because dwarfism is relatively uncommon, children may feel isolated from their peers.
