Lung Inflammation

As your body’s immune system keeps trying to clear the infection from your lungs, this process can result in chronic irritation and swelling, or inflammation.

Who is at risk for bronchiectasis?

BE develops for many reasons, and they can differ from person to person. Certain medical conditions put people at risk, such as:

  • Coughing

     or asthma

  • Infection in lungs

    Repeated respiratory infections, like pneumonia, TB, or

  • Flame

    Inflammatory diseases, like RA or IBD

  • Broken shield

    A weakened immune system, like immunodeficiency disorders

  • Stomach

    Aspiration syndromes, like GERD

  • DNA

    Inherited (genetic) disorders, like PCD or alpha-1 antitrypsin deficiency

Some people may have bronchiectasis and not realize it:

  • Approximately 1 in 4 people with COPD may also have bronchiectasisa
  • Approximately 1 in 3 people with asthma may also have bronchiectasisb

footnoteaStudies have shown a range of 20% to 69% of people.

footnotebStudies have shown a range of 2% to 47% of people.

GERD=gastroesophageal reflux disease; IBD=inflammatory bowel disease; NTM=nontuberculous mycobacteria; PCD=primary ciliary dyskinesia; RA=rheumatoid arthritis; TB=tuberculosis.

What are the symptoms of bronchiectasis?

Bronchiectasis symptoms can look like those from other lung conditions. Some common symptoms of BE are:

  • Coughing

  • Mucus production, which may contain blood or be hard to cough up

  • Difficulty breathing, shortness of breath, or wheezing

  • Fatigue

  • Fever, chills, and/or body aches

  • Frequent lung infections

  • Chest pain

When surveyed about their symptoms, people with BE shared concerns about having a constant cough, shortness of breath, fatigue, and feeling misunderstood, embarrassed, and anxious about the potential for future BE flares.

Many BE symptoms overlap with other conditions, which is why there may be a delay in diagnosis.
