My boyfriend has copd at age 20, what can we expect?

Depends...: COPD normally occurs in older patients but i diagnosed a patient in his twenties with copd. Turns out he had alpha-1 antitrypsin deficiency, a genetic disorder. Suggest that your boyfriend get screened for this as early treatment may prevent further lung damage. COPD in general can be treated with medications to relieve symptoms & slow down the progression of this disease.
