Asthma is a respiratory system disorder in which the passages that allow air to pass into and out of the lungs periodically narrows, causing coughing, wheezing, and shortness of breath. This narrowing is typically temporary and reversible, but in severe attacks, asthma may result in death. Asthma most commonly refers to bronchial asthma, an inflammation of the airways, but the term is also used to refer to cardiac asthma, which develops when fluid builds up in the lungs as a complication of hear failure. This report focuses on bronchial asthma.
