Once the doctor has obtained a detailed medical history, run some tests, and diagnosed you as having asthma, your asthma will be classified. This helps determine the treatment plan. It should be classified again at every office visit. There are four levels of severity:

Mild Intermittent Mild Persistent Moderate Persistent Severe Persistent

Click the buttons above to see the four levels of asthma severity. Asthma is classified based on how often symptoms occur during the day, how often they occur at night, and spirometry results.

In some cases, your doctor may use "peak flow" measurements to help assess your asthma severity instead of spirometry . Peak flow is a simple method of self monitoring that is described later.

Take note

Regardless of your asthma's classification, any single asthma episode can range from mild to severe. This is true for anyone with asthma.
