Dwarfism is a medical term used to describe a person who is shorter than 4’10” when fully grown and meets several other distinctive physical criteria. There are over 200 different recognized types of dwarfism, and most common include arms and legs that are disproportionate to the size of the head and trunk. Most children with dwarfism are born to parents of normal stature. Generally, dwarfism does not affect a child’s IQ, and most children born with dwarfism learn to adapt their environments to live normal lives.
