Allergic asthma is a chronic disease that affects the airways and, in particular, the bronchi, which are the channels that allow the passage of air to and from the lungs.
In allergic asthma sufferers, the inner walls of the airways are particularly sensitive to the action of substances that are normally harmless to most people, and when they come into contact with allergenic or irritant molecules, they become inflamed, “swell,” and bronchospasm sets in.
This reduces the space available for the passage of air to and from the lungs, resulting in difficulty in breathing normally and feelings of suffocation.
