Brady careful about what he endorses. JACKSONVILLE, Fla. -- He is admired by some and adored by others.

Last updated: Apr 01, 2009. The most common symptoms of chronic obstructive pulmonary disease (COPD) are persistent cough, shortness of breath, feeling like you can't breathe, and excess mucus or phlegm. However, the symptoms can vary, depending on the amount of lung damage.
Progressive means the disease gets worse over time. COPD can cause coughing that produces large amounts of mucus (a slimy substance), wheezing, shortness of breath, chest tightness, and other symptoms. Cigarette smoking is the leading cause of COPD.
