Asthma :
Asthma is a respiratory ailment that is caused by blocked airway passages. The person experiences difficulty in breathing as the airways become narrow due to collection of mucous.
Symptoms of asthma range from coughing, wheezing, tightness of chest, etc. If left untreated, asthma can turn into a chronic condition. Asthma may become worse soon after indulging in rigorous exercise, or being exposed to an environment where there are irritants that can trigger an asthma attack. Sometimes, the seasonal changes can also trigger an asthma attack when there is a rise in airborne pollen.
