Asthma is a common lung problem that causes breathing difficulties for people of all ages, though most people develop the condition in childhood. The severity of an asthma attack varies from person to person and even event to event. Luckily, fewer than one in 20 people with asthma require specialist care. Most control the condition and its symptoms with inhalers and medication.
Shortness of breath is one of the most common symptoms of asthma. The muscles around the airways tense, causing the airways to narrow, which can result in bronchospasms and airway inflammation. The body creates mucus to address this reaction, and the lungs become less efficient in transferring oxygen to the small blood vessels on the surface of the lungs.
