What is COPD?
Chronic obstructive pulmonary disease (COPD)2 is a progressive lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. People with COPD are also likely to experience episodes called exacerbations, during which their symptoms become worse than usual day-to-day variation and persist for at least several days. It’s caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. COPD is treatable. With proper management, most people with COPD can achieve good symptom control and quality of life, as well as reduced risk of other associated conditions.
What is Asthma?
Asthma is a chronic lung disease3 that intermittently inflames and narrows the airways in the lungs. The inflammation causes the airways to swell, making it harder to move air in and out of your lungs. Asthma causes periods of wheezing, chest tightness, shortness of breath and coughing. People who have asthma may experience symptoms that range from mild to severe and that may happen rarely or every day. When symptoms get worse, it is called an asthma attack. Asthma affects people of all ages and often starts during childhood. The goal of asthma management is to achieve control with an asthma action plan. An asthma action plan may include monitoring, avoiding triggers, and using medicines.
What is Bronchiectasis?
Bronchiectasis4 is a condition affecting the airways in the lungs that causes cough, increased mucus production, and recurrent lung infections. The symptoms are caused by abnormal widening of the airways of the lung, also known as bronchi. The cells lining the airways become inflamed and swollen. These damaged airways can no longer effectively clear mucus and bacteria from the lung. This can lead to flare-ups of cough, mucus production, and shortness of breath.
Bronchiectasis is caused by one or more infections introduced into the lungs. People with bronchiectasis are more likely to get lung infections. Each lung infection can make the bronchiectasis worse. Therefore, early diagnosis and treatment of bronchiectasis is very important.
