Living with Idiopathic bronchiectasis

A long-term lung condition in which the airways widen and their walls are damaged, with no clear cause found.

Understanding Idiopathic bronchiectasis

Idiopathic bronchiectasis is a progressive lung disease with lasting widening of the airways (bronchi) and damage to their walls, without a known underlying cause.

It is diagnosed when no other cause is found, such as past infection, aspiration, immune problems, birth differences, or cilia (tiny airway hairs) problems. It can start at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Wet cough
  • Trouble breathing
  • Repeated chest infections
  • Coughing up blood
  • Wheezing
  • Chest pain

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and lung and breathing specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
