Asthma - Overview
Many things can trigger asthma: allergens, poor air quality, physical activity, and even stress. Once inflamed, bronchial tubes close up, making breathing difficult. Extra mucus can further block air passages as the tubes tighten. This can cause wheezing, coughing, and life-threatening asthma attacks.While there is no cure for asthma, treatment is usually very effective. Working with a physician who tracks your symptoms is the best way to live a healthy life and keep asthma under control.
