Asthma is a chronic disease involving the airways in the lungs. These airways, or bronchial tubes, allow air to come in and out of the lungs. This makes it difficult for air to move in and out of the lungs.
Airborne substances, such as pollen, dust mites, mold spores, pet dander or particles of cockroach waste.
Respiratory infections, such as the common cold.
Physical activity (exercise-induced asthma)
Air pollutants and irritants, such as smoke.
Asthma can usually be managed with rescue inhalers to treat symptoms (albuterol). Severe cases may require longer-acting inhalers that keep the airways open, as well as oral steroids.
Symptoms / Signs
Cough, difficulty breathing, wheezing, breathing through the mouth, fast breathing, frequent respiratory infections, rapid breathing, or shortness of breath at night
Staying current with vaccinations can prevent flu and pneumonia from triggering asthma flare-ups. A number of outdoor allergens and irritants ranging from pollen and mold to cold air and air pollution can trigger asthma attacks.
