What is severe asthma?

Severe asthma is a chronic lung disease that is characterized by severe and persistent airflow limitation. It is usually associated with frequent exacerbations, such as asthma attacks, and requires high doses of inhaled or oral medications, or even systemic corticosteroids (a type of steroid medication). People with severe asthma may experience symptoms such as chest tightness, shortness of breath, wheezing, coughing, and a reduced quality of life. It is important to work closely with a healthcare provider to manage severe asthma, as it can be life-threatening if not properly controlled.
