What Are The Symptoms Of Chronic Obstructive Pulmonary Disease?

Chronic obstructive pulmonary disease (COPD) may cause long-term difficulties in breathing, seemingly because this common condition affects the lungs. Many consider this to be an overarching condition with two types: chronic bronchitis and emphysema. However, patients appear to deal with both of these. What does seem clear is that smoking is the likely main cause of COPD. Doctors can use a variety of diagnostic tests. This may include chest x-rays, lung function tests, and CT scans.
