People with cystic fibrosis may have Pa     bacteria     in their lungs and not notice any symptoms at first. However, when the Pa infection becomes more severe, they notice symptoms of infection and inflammation   , including frequent coughing and tightness in the chest.

As the inflammation and infection get worse, patients may find it harder to exercise, get tired faster, and have shortness of breath. Inflammation can lead to more severe blockage of the breathing tubes to the lungs and permanent damage to the airways. When the infection and inflammation decrease, these symptoms may also lessen.

If you are experiencing these symptoms, you should see your doctor. Pa infections are usually diagnosed through a sputum or throat culture.

Repeated Pa infections are common in people with cystic fibrosis.
