Overview

Psychogenic dwarfism, Psychosocial short stature or Stress dwarfism is a growth disorder that is observed between the ages of 2 and 15, caused by extreme emotional deprivation or stress.

Psychogenic dwarfism is short stature that results from an environment with constant and extreme stress. Usual signs and symptoms include short stature, weight that is inappropriate for the height, and immature bone age, an adult height around 4 feet (about 122 centimeters). For diagnosis, evaluation of child’s growth and develpment environment, appearance examination and measurements of height and weight, hormone tests and imaging technology may be helpful. Treatments for most dwarfism-related conditions don’t increase stature but may lessen complications. Children of psychogenic dwarfism may receive hormone therapy for a long time. Prognosis of psyvhogenic dwarfism varies from condition to condition, from person to person. Family support, social networks, advocacy groups and adaptive products enable most patients to address challenges in educational, work and social settings.

Causes

Overview

Causes

Children with psychogenic dwarfism have extremely low levels of growth hormone. These children possibly have a problem with growth hormone inhibiting hormone (GHIH) or growth hormone releasing hormone (GHRH). The children could either be unresponsive to these hormones or too sensitive.

Children that have psychogenic dwarfism exhibit signs of failure to thrive. Even though they appear to be receiving adequate nutrition, they do not grow and develop normally compared to other children of their age.

An environment of constant and extreme stress causes psychogenic dwarfism. Stress releases hormones in the body such as epinephrine and norepinephrine, engaging what is known as the ‘fight or flight’ response. The heart speeds up and the body diverts resources away from processes that are not immediately important; in psychogenic dwarfism, the production of growth hormone (GH) is thus affected. As well as lacking growth hormone, children with psychogenic dwarfism exhibit gastrointestinal problems due to the large amounts of epinephrine and norepinephrine, resulting in their bodies lacking proper digestion of nutrients and further affecting development.

Risk Factors

Overview

Risk Factors

Many studies have demonstrated that an environment with constant and extreme stress is the cause of psychogenic dwarfism for children. Stress releases hormones in the children’s bodies such as epinephrine and norepinephrine, engaging what is known as the “fight or flight” response, decreaseing the production of growth hormone (GH), resulting in dyspepsia of nutrients and further affecting growth and development.

Prognosis

Prognosis of psyvhogenic dwarfism varies from condition to condition, from person to person. Most psychogenic dwarfism have good outcomes with hormone therapy. Family support, social networks, advocacy groups and adaptive products enable most people with psychogenic dwarfism to address challenges in educational, work and social settings.
