If you or your child has been diagnosed with asthma, work with your doctor to learn how manage it yourself. You can work with your doctor to develop a treatment plan, called an asthma action plan.

Most people who have asthma are treated with daily medicine, called long-term control medicines, along with inhalers containing medicine for short-term relief during an asthma attack or when symptoms worsen.

Your doctor may diagnose asthma based on your medical history, a physical exam, and results from diagnostic tests. Your history of asthma symptoms will help your doctor determine if you have mild, moderate, or severe asthma.

How often asthma symptoms occur may depend on how severe, or intense, the asthma is, and whether you are exposed to allergens. Some people have symptoms every day, while others have symptoms only a few days of the year.

There is no routine screening for asthma, and there is no way to prevent asthma. Your doctor may recommend avoiding triggers to help prevent asthma from getting worse or causing asthma attacks.
