Asthma is inflammatory disease of the airways of lungs. Asthma is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness and coughing and difficulty in brining up the sputum. Symptoms are usually worse at night and early morning and/or in response to exercise or cold air. The episodes may occur few times a day or few times a week.
Asthma is a combination of genetic and environmental factors. Asthma may be classified as Atopic and non-atopic. Onset before the age of 12 is more likely due to genetic influence, while onset after 12 is more likely due to environmental influence.
Triggering factors: Different individuals react to various factors in different ways, hence identifying individual triggering factor is more important in management and treatment of asthma.

CBP with ESR
Prevention and Management: WHO recommends decreasing risk factors such as tobacco smoke, air pollution, and the number of lower respiratory infections. A specific, customized plan for proactively monitoring and managing symptoms should be created. The best effective management is identifying the triggering factors and eliminating them from exposure, nothing but lifestyle modifications.
