Q: What is asthma?
Asthma is a medical condition of the lungs which causes inflammation and narrowing of the air passages. Those with asthma commonly have to deal with coughing, wheezing, chest tightness, and shortness of breath. In most cases, coughing takes place early in the morning or late in the evening. When the air passages are swollen because of asthma and something irritating is inhaled, the muscles in the air passages can constrict and become even more inflamed. Cells in the airways can also begin to produce a thick mucus, further narrowing the airways. When all these side effects combine, more extreme asthma symptoms take place and breathing is extremely difficult.
