Symptoms can change over time, as your asthma changes. Talk with your doctor about an asthma action plan that’s tailored to you and your asthma. Your doctor will help you identify the right trigger factors – the thing that makes your symptoms worse – so they can be avoided in the future. He or she might ask you if there are any situations where it’s hard for you to breathe, or where it’s hard for someone else (for example at school or work) to see that you’re having an attack. An asthma action plan is a good way of preparing for an attack and maximizing your asthma control.
