Managing the allergic cough
Keywords: allergic cough
AbstractCoughing is a protective reflex action that occurs when the airway is irritated or obstructed. Its purpose is to clear the airway so that breathing can continue normally. Doctors classify coughs into two categories: • Acute cough that lasts for less than three weeks • Chronic cough that lasts for more than three weeks An acute cough is usually caused by a viral infection of the upper respiratory tract, such as the common cold. Cigarette smoke is the most common cause of chronic cough, but a chronic cough may also be a symptom of postnasal drip, asthma, chronic obstructive pulmonary disease (chronic bronchitis and emphysema), tuberculosis or acid reflux from the stomach.
