Other types are seen at birth. Most pregnant women have a prenatal ultrasound to measure the baby's growth at around 20 weeks. At that stage, features of achondroplasia aren't yet noticeable.

But many children with achondroplasia aren't diagnosed until after birth. Doctors can recognize some other types of skeletal dysplasia earlier in pregnancy. Others aren't noticed until the first few months or years of life, when a child's growth slows. A health care provider may take X-rays after birth to check for bone changes. Doctors also may use genetic testing before or after birth to confirm the diagnosis. Each condition that causes dwarfism has its own possible medical complications, which can change over time.
But doctors can treat many of these. Children with dwarfism are cared for by doctors who specialize in orthopedics, neurosurgery, ENT, and pulmonology. Some medical concerns are treated with surgery.

People with dwarfism should try to keep a healthy weight. A few extra pounds can puts harmful stress on the back and joints. It's important for them to find safe and enjoyable physical activities. People with dwarfism can lead healthy, active lives. The Americans with Disabilities Act protects their rights. Types of skeletal dysplasia and the severity of medical needs vary from person to person.
