Allergies and Asthma: KNOW the signs to find relief

Signs that you're having an allergic reaction can be sudden and severe. Or they can be subtle and similar to other health conditions, making it harder to know based on symptoms alone.

Allergies, including asthma, are:

  • The fifth leading chronic disease in the U.S. for people of all ages
  • The third most common chronic disease for children under 18 years*

*Asthma and Allergy Foundation of America


You're less likely to have an uncomfortable or life-threatening reaction once you know which allergens to prepare for or avoid. The first step is identifying if and when you experience allergy-like symptoms.
