If you have asthma, you are at an increased risk of bronchitis.
When the two conditions occur together, symptoms such ascoughingandshortness of breathcan be compounded.
Asthma is characterized by chronic lung inflammation and swollen and irritated airways.

A history of viral respiratory infections at an early age is a risk factor for asthma.
This may be due to lung damage or developmental lung changes triggered by the infection.
Furthermore, the lung function impairment that occurs in childhood asthma may predispose to chronic bronchitis later in life.
Asthma symptoms may also start or get worse with viral infections.
Triggers vary from person to person.
Chronic bronchitis leads to chronically irritated airways, decreased airflow, and scarring of the lungs.
You will have a physical exam.
Testing possibilities include:
You might have PFTs before and after you use abronchodilator medication.
If airway obstruction persists after you use the medication, it could indicate that you have chronic bronchitis.
Diagnosis using PFTs can be complicated and diagnostic confusion sometimes occurs.
