COPD

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It is caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

Symptoms of COPD could include: Shortness of breath, wheezing, chest tightness, clearing of the throat due to excess mucus in the lungs, chronic cough that may produce mucus, blueness of the lips or fingernail beds, frequent respiratory infections, lack of energy, unintended weight loss, and swelling in ankles, feet or legs.
