The most common risk factor for COPD is Tobacco Smoking which is considered to be an Environmental Factor. They often occur together. But before we do that you should have good knowledge of the Anatomy and Physiology of the Respiratory System. In fact, smoking harms the airways in many different ways: COPD can also be a genetic problem, specifically a deficiency in Alpha1-Antitrypsin. Most cases of COPD, and therefore emphysema, are caused by cigarette smoking (but not all!). I hope that you mentioned at least 3 different causes, if not go back and reread the list of risk factors. The symptoms of COPD can be treated; however, the airflow limitation is not fully reversible. Shahab, Jarvis, Britton and West (2006) suggest that COPD is a major contributor to global mortality and morbidity and its worldwide prevalence is likely to increase further. Gradually, this damage causes the air sacs to rupture and create one big air pocket instead of many small ones. 2017 Oct 26. JAMA Intern Med. The poor airflow is the result of breakdown of lung tissue (known as emphysema), and small airways disease known as obstructive bronchiolitis. A person with chronic bronchitis typically has a daily cough with phlegm that lasts for months at a time over several years. CrossRef Google Scholar In this type, expiration becomes an active movement requiring muscular effort rather than a passive action. Chronic bronchitis causes inflammation in the tubes (called bronchi) that carry the air to and from your lungs. Chest. It includes: emphysema – damage to the air sacs in the lungs; chronic bronchitis – long-term inflammation of the airways; COPD is a common condition that mainly affects middle-aged or older adults who smoke.
