COPD Chronic Obstructive Pulmonary Disease

COPD is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production, and wheezing. It is typically caused by long-term exposure to irritating gases or particles, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer, and a variety of other conditions.

Signs and symptoms of COPD may include:

• Shortness of breath, especially during physical activities
• Wheezing
• Chest tightness
• A chronic cough that may produce mucus (sputum) that may be clear, white, yellow, or greenish
• Frequent respiratory infections
• Lack of energy
• Unintended weight loss (in later stages)
• Swelling in ankles, feet, or legs
