Supermodel Christy Turlington is among the youngest celebrities with COPD. At the height of her modeling career, when she was only 31, Turlington was diagnosed with early-stage emphysema. By then, she had been smoking for more than 15 years. COPD patients are most commonly people age 40 and older, Dr. Martinez said. But as celebs like Turlington indicate, COPD can develop at a younger age.
