Asthma Basics CenterAsthma is a chronic inflammation of the body’s bronchial (airway) tissues. People with asthma experience shortness of breath, chest tightness, coughing and wheezing. These symptoms intensify during an asthma attack, which occurs when exposure to allergens or other stimuli further inflame the airways, leading to an inability to expel trapped air from the lungs.
