World Asthma Day


Asthma is a common lung disease affecting millions of people worldwide. It is characterized by narrowing of the airways (breathing tubes) in the lungs. This narrowing is partially or completely reversible.

Symptoms of asthma include wheezing, coughing, chest tightness, and shortness of breath. These symptoms tend to come and go, and are related to the degree of airway narrowing in the lungs.

The airways are sensitive to a variety of stimuli, which may include viral illnesses (eg, the common cold), allergens, exercise, medicines, or environmental conditions.

Asthma can usually be treated successfully. This requires being well informed about the disease and being active in managing it.
