Asthma affects more than eleven million adults and children in the United States. Anybody can get it at any age. The exact cause of asthma is not known, but it does seem to run in families. People with asthma may be supersensitive to various substances and environmental conditions that are normally harmless. Some common triggers may include allergens such as pollen, animal dander, dust, and dust mites as well as irritants such as smoke, fumes, and strong odors.
