Asthma is a chronic lung disease that makes breathing difficult. There is no cure but it can be managed to live a normal life. Common symptoms include wheezing, coughing, shortness of breath, and chest tightness. Treatment involves medications like bronchodilators to open airways and anti-inflammatories to reduce swelling. Managing asthma triggers at home, school, and work can help control symptoms. Advocating for policies that improve air quality can benefit people with asthma.
