Extrinsic asthma: Extrinsic asthma is a type of asthma that is triggered by an exposure to an allergen. Extrinsic asthma involves constriction and inflammation of the airways in response to exposure to the allergen. Examples of possible allergens include dust mites, pollen and mould. The severity of symptoms and allergen involved is variable. More detailed information about the symptoms, causes, and treatments of Extrinsic asthma is available below.
There is no cure but avoiding the triggers will prevent symptoms developing. Various measures can be used to limit this exposure e.g. limit outdoor activities when high pollen counts are high. Symptoms may be managed by various asthma medications such as bronchodilators, antiinflammatories and asthma inhalers. Some medications act as long-term controllers (e.g. corticosteroids, long-acting beta ...more treatments »
