Asthma is a chronic condition that affects the airways. It causes wheezing and can make it hard to breathe. Some triggers include exposure to an allergen or irritant, viruses, exercise, emotional stress, and other factors. Asthma is a long-term condition affecting the airways. It involves inflammation and narrowing inside the lungs, which restricts air supply. Asthma causes the inside walls of the airways, or the bronchial tubes, to become swollen and inflamed. During an asthma attack, the airways will swell, the muscles around them will tighten, and it becomes difficult for air to move in and out of the lungs.
