Asthma is caused by an inflammation and obstruction of the bronchial tubes, the tubes that help the lung inhale and exhale air. In 2009, the American Academy of Asthma, Allergy and Immunology stated that one in every 12 people in the United States had a diagnosis of asthma, compared to one in 14 in 2001. During an asthma attack, the muscles around the bronchial tubes tighten and swell, which narrows the air passages and thus makes it difficult for the person to breathe. Common triggers of asthma attacks include exposure to an allergen (like grass, tress, pollen, etc.), irritants in the air (such as smoke or strong smells), illnesses (like the flu), stress, extreme weather conditions (such as extreme heat), or physical exertion and exercise.
