KNOW Asthma causes the airways of the lungs to swell and become narrower. This can make it hard to breathe and cause wheezing as you breathe in and out. Asthma cannot be cured, but can be relieved with medicine.
Repeat attacks are common.
Causes Triggers may include pollen, dust, animals, molds, some foods, lung infections, smoke, exercise, high amounts of air pollution, or stress. Symptoms Common symptoms include trouble breathing, a tight feeling in the chest, and wheezing. During a bad asthma attack, you may sweat and have real difficulty breathing. Your lips and nailbeds may turn a pale or blue color, your heart may beat faster and you may become very anxious. Care Most of the time you can care for yourself at home.
