Bronchiectasis is a long-term condition where the airways of the lungs known as bronchi become abnormally widened, leading to a build-up of excess mucus that can make the lungs more vulnerable to infection.
When an infection develops it leads to further damage and in turn more mucus production leading to more infection and thus forming a vicious cycle. Over time this cycle can increase the area of damage inside the lungs.
By far the commonest cause of Bronchiectasis in our country is Tuberculosis or previous severe respiratory infections like pneumonia that has damaged lungs. Several other disease can cause bronchiectasis. These include:
The most common symptoms are:
If the diagnosis is suspected based on a detailed history of symptoms and the findings on physical examination, the following tests are needed to evaluate and confirm the diagnosis:
X-ray or Chest CT scan- imaging tests to show the state of the lungs.
Blood tests and sputum cultures- to find out if there are infections.
Lung function tests- to determine how well a patient can breath in order to assess the impact of disease and also to assess fitness for any treatment.
Bronchoscopy- A bronchoscopy may be required wherein a light and a camera on a tube is inserted through the nose or mouth into the windpipe and then down into the lungs. In the case of blockages, a bronchoscopy can also find and remove the object blocking the airways. The procedure can also be used to obtain lung secretions by Bronchoalveolar lavage (BAL) which is sent for microbiological studies to rule out infection.
Bronchiectasis is a permanent damage and, in most circumstances, cannot be cured. But it can be managed and the aim of the treatment is to treat the infection and improve the symptoms along with prevention of exacerbations.
Treatment of the underlying condition causing bronchiectasis like Tuberculosis or other immune system disease must be treated first.
