- Asthma is a chronic inflammatory disease of the airways. The manifestations of Asthma and COPD are quite similar and it becomes difficult to tell the difference. However, onset of asthma is generally at a younger age.
- Generally a family history is present. Often there is a history of an allergic disease like rhinitis, eczema etc.
- Bronchiectasis is a condition characterized by irreversible dilatation of the bronchial tubes. It is caused by chronic inflammation and infection of the airways.
- It is marked by production of copious and purulent sputum and is often associated with frequent bacterial infections.
- Bronchiolitis Obliterans is a rare disease. In this condition, the bronchioles become narrow and compressed due to scarring and inflammation.
- The symptoms of Bronchiectasis obliterans are similar to COPD and include cough, shortness of breath and wheezing. However, this is a very life-threatening and non-reversible condition.
