Asthma is a chronic condition affecting the respiratory system. It is characterized by intermittent “attacks,” during which the patient suffers sudden and acute problems breathing. Asthma attacks may be brought on by a number of factors, including intense physical activity and exposure to allergens. It is one of the most common respiratory conditions in the world, and can be effectively managed through the use of inhaled corticosteroids and by minimizing exposure to environmental triggers. With proper management, the harmful and dangerous effects of the condition can be effectively controlled, with most patients going on to enjoy relatively normal qualities of life.
