Definition

By Mayo Clinic staff

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 or less (147 centimeters). The typical range in adult height among people with dwarfism is 2 feet 8 inches (81 centimeters) to 4 feet 8 inches (142 centimeters).

Treatments for most dwarfism-related conditions don't increase stature but may lessen complications.

Many people with dwarfism encounter discrimination. Family support, social networks, advocacy groups and adaptive products enable most people with dwarfism to address challenges in educational, work and social settings.
