Bronchial Asthma Symptoms - Oren Zarif

In most cases, bronchial asthma begins as simple bronchitis. A dry cough with viscous secretions may indicate the onset of an asthma attack. The mucous membranes in the bronchi swell and produce increased mucus, which obstructs air passages. Bronchial asthma causes the cough reflex and is often accompanied by shortness of breath.
