Astounding Medical Mysteries
Kristin was born full-term weighing just 2 pounds, 11 ounces and 15 inches long—75 percent smaller than the average baby. Doctors suspected Kristin had a rare form of dwarfism, but most dwarfs have normal-size torsos and heads with shorter limbs and bowed legs. In Kristin's case, everything was proportionate—just very tiny.
When she was 8 years old and just 2'9" tall, doctors finally diagnosed Kristin with primordial dwarfism—a disorder she shares with only 100 people in the world.
