Mythbuster: Are certain allergies more “severe” than others?

November 26, 2018

FACT: There are no markers or measurements to predict the severity of a patient’s allergy.

Many factors can affect reaction severity including the amount eaten, a delay in giving or lack of epinephrine and poor asthma control. Age can also be a factor: youth or teens may have more severe reactions because of risk-taking behaviour with eating and denying their symptoms.

There are also important “co-factors,” such as alcohol, exercise and certain medications, that can influence the severity of food allergic reactions by lowering the threshold for a reaction in some people.

Bottom line: If you have more than one food allergy, each allergy should be taken as seriously as the others.
