J44.09: Chronic obstructive pulmonary disease with acute lower respiratory infection, unspecified FEV
The airways in your lungs are constricted. In addition, you have been infected with a pathogen. As a result, you have more severe symptoms than usual.
The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways.
In your case, the small airways in the lungs are constricted. The small airways are also permanently inflamed. As a result of an inflammation like this, the wall of the small airways is changing. Due to the inflammation, the airways are also forming a lot of mucus. One frequent cause of this disorder is smoking.
Your lower respiratory tract is additionally inflamed by pathogens. As a result, your symptoms have suddenly worsened.
