During an asthma attack, the lining of the bronchi becomes swollen, causing a narrowing of the airways and a decrease in the air flowing into and out of the lungs, according to the World Health Organization (WHO).
For people with sensitive airways, chronic asthma symptoms can be triggered by inhaling substances called allergens, according to Medline Plus website. Other causes may include taking certain medications, changes in climate, air or food chemicals, exercise, mold, pollen, respiratory infections (such as common colds), strong emotions and second-hand smoke.
Cough with or without sputum (phlegm), retraction or pulling of the skin between the ribs when breathing (intercostal retractions), shortness of breath that gets worse with exercise or activity, and wheezing (high-pitch whistling sound made while breathing) are the most common symptoms of a respiratory disease and in some cases, if they worsen, they may require medical treatment. There is no cure for asthma. Therefore, it is recommended that the patient be diagnosed in time, so as to prevent the condition from interfering with their lifestyle.
