Question: Asthma Control - How Do I Tell if My Asthma Is Under Control?

Asthma control is the always the basic goal of asthma treatment. Without asthma control, your asthma symptoms can quickly spiral downward, resulting in serious health problems. But many people with asthma wonder -- what clues are there to the degree of asthma control? How do I know if my asthma is controlled or not?

Answer: The best way to know your level of asthma control is by evaluating how you are feeling. The national asthma guidelines that govern asthma treatment outline control in terms of 3 main factors:
  • Presence / frequency of asthma symptoms
  • Peak flow readings
  • Asthma's interference in your daily activities

Basically, if you are having asthma symptoms, your peak flow readings are not at your personal best level and / or asthma is interfering with your ability to participate in home, work, or play activities, then your asthma control is probably not where it should be.

Another sure-fire sign that asthma control is slipping? If you're using your rescue / quick-relief inhaler more than twice a week.

For more information on why control is so important, how it is defined, and the role your Asthma Action Plan plays in helping you maintain asthma control, see our article on Asthma Control and Other Asthma Treatment Goals.
