Asthma Causes and Triggers No one really knows what causes asthma. What we do know is that asthma is a chronic inflammatory disease of the airways. The causes of asthma symptoms can vary from person to person. Still, one thing is consistent with asthma: when airways come into contact with an asthma trigger, the airways become inflamed, narrow, and fill with mucus.

What is asthma? People with asthma are born with airways that are super-sensitive to things, called triggers, that do not bother other people with normal lungs. These triggers start lung inflammation and asthma symptoms. There are three major groups of triggers: Infections such as colds and sinus infections. Every asthma patient has a problem with this trigger. Allergies to pollen (tree, grass, weeds), molds, pets, dust mites and cockroaches. Irritants such as tobacco smoke and chemical fumes from heaters.

Pathophysiology of asthma Obstruction of the lumen of the bronchiole by mucoid exudate, goblet cell metaplasia, epithelial basement membrane thickening and severe inflammation of bronchiole. During an asthma episode, inflamed airways react to environmental triggers such as smoke, dust, or pollen. The airways narrow and produce excess mucus, making it difficult to breathe. In essence, asthma is the result of an immune response in the bronchial airways. The airways of asthma patients are  hypersensitive  to certain triggers, also known as stimuli (see below).
