    How to diagnose Dwarfism ?
    ### Response:
    How is dwarfism diagnosed? Some types of dwarfism can be identified through prenatal testing if a doctor suspects a particular condition and tests for it. However, most cases are not identified until after the child is born. In those instances, the doctor makes a diagnosis based on the child's appearance, failure to grow, and X-rays of the bones.
