Bronchiectasis: Meaning, Types, Causes, Symptoms & Treatment 

Updated on 3 November 2023

Bronchiectasis is a condition in which damage to the tubes in the lungs (airways) causes the sacs to dilate or swell. This can make it difficult for mucus to clear from the lungs and lead to frequent infections. A cough with lots of pus and mucus is the main symptom of bronchiectasis. Like bronchiolitis, bronchiectasis cannot be cured but it can be managed with symptom treatment.

What is Bronchiectasis?

Bronchiectasis is a lung disease in which the airways (tubes leading to the lungs) become damaged and enlarged. Damaged airways cannot clear mucus normally. The bacteria then grow in the mucosa causing more inflammation and damage to the lungs. This causes a violent cough as the body tries to expel the infected mucus. The tubes that enter the lungs (airways or bronchi) have a cap to protect them from disease. Although sometimes inflammatory saliva is one of these defences. When mucus cannot be removed it can cause long-term damage to the airways.

Any harmful particles in the mucus get trapped in the airways during inhalation of air. Then millions of tiny hair-like structures (cilia) use a coordinated movement like waves to wash the mucus out of the lungs. This is called mucociliary clearance. When someone coughs or swallows mucus, part of this system malfunctions—if the cilia are damaged or mucus is blocked in the airways—the trapped molecules are broken down by stomach acid in case of a build-up mucus in the lungs. Bacteria get trapped in the mucus and multiply causing infection. Damage caused by such infection can make bronchiectasis worse.

Sometimes, depending on bronchiectasis causes, the symptoms may be moderate, but one can have a sudden flare-up resulting in an exacerbation. Bronchiectasis symptoms get worse during such episodes. Aggravating symptoms include:

  • Extreme fatigue
  • Fever
  • Chills
  • Shortness of breath
  • Night sweats

Types of Bronchiectasis

There are two main categories of bronchiectasis - cystic and non-cystic fibrosis.

Cystic Fibrosis Bronchiectasis (CFB)

Cystic fibrosis (CF) is a genetic condition in which thick mucus builds up in patients' lungs causing recurrent pulmonary infections. Similar to bronchiectasis, each cycle of inflammation and infection progressively damages the bronchi, and patients show signs of bronchiectasis.

Non-Cystic Fibrosis Bronchiectasis (NCFB)

Patients can also develop bronchiectasis outside of CF. For instance, if a patient is living with COPD (chronic obstructive pulmonary disease); has damaged cilia (tiny hair-like structures inside the bronchial tube that help clear mucus in the lungs); experiences asthma; or has impaired muscular and nervous system functions that prevent them from clearing mucus naturally, they may develop bronchiectasis symptoms.

Who is Affected by Bronchiectasis?

People with conditions that damage the lungs or increase the risk of lung infections are at risk for bronchitis. Examples of such conditions include,

  • Cystic fibrosis is the main bronchiectasis cause
  • A common variable is immunodeficiency and less commonly HIV and AIDS
  • Allergic bronchial aspergillosis is an allergic reaction to a fungus called Aspergillus
  • Disorders affecting ciliary function such as primary ciliary dyskinesia can cause bronchiectasis
  • Chronic (long-term) pulmonary aspiration that irritates the airways
  • Connective tissue diseases such as rheumatoid arthritis, SjÃļgren's syndrome
  • Crohn's disease

Is Bronchiectasis a common condition?

Bronchiectasis is a common but often ignored disease. Most of the epidemiological data can be traced to cohorts in the USA and Europe. Cases in low and middle-income countries are low or not reported and diagnosed. In India, the previous history of tuberculosis is often considered to be one of the main bronchiectasis causes.

Bronchiectasis treatment

Bronchodilator therapy helps reduce inflammation to kill bacteria and clear infected mucus. The most common bronchiectasis treatment includes,

  • Antibiotics: They can treat infections caused by bacteria.
  • Macrolides - Drugs that treat both infection and inflammation.
  • Expectorants and mucolytics - These medicines thin mucus and help with coughing.
  • Physical therapy.
  • Postural drainage and chest thrusts can help loosen and eliminate mucus.
  • Breathing exercises help open the airways.
  • Medical equipment - Oscillating positive airway pressure (PEP) devices and shock absorbers can malfunction and force mucus out of the lungs.

What is the difference between bronchitis and bronchiectasis?

Bronchiectasis symptoms are similar to those of bronchitis including mucus in the lungs and cough. But bronchiectasis causes permanent enlargement of the airways, whereas bronchitis is a temporary infection that does not cause permanent damage. The discourse on bronchiectasis vs bronchitis goes back a long way. And people often mistake one for the other. But they are significantly different in their impacts. It is thus important to do enough research on bronchitis vs bronchiectasis.

In conclusion, bronchiectasis is a chronic lung condition that can lead to serious health complications if left untreated. It is most advisable to seek guidance from a medical practitioner before proceeding with any form of bronchiectasis treatment.
