Can you develop food allergies as an adult?

(NC) Most people assume food allergies are a childhood condition that you either grow up with or outgrow. But for a growing number of Canadians, the first signs are showing up later in life.

“Adult-onset allergies are more common than people realize,” says Dr. Harold Kim, an allergist and immunologist. “The challenge is that adults are more likely to dismiss symptoms or assume it was something else, and that can be dangerous.”

When symptoms don’t seem serious

Symptoms like hives, upset stomach, scratchy throat or even chest pain after eating can be easy to blame on stress, a stomach bug or acid reflux. This tendency to explain away reactions can delay a proper diagnosis and leave you unprepared to respond if a severe reaction happens.

Why reactions can change over time

Allergic reactions don’t always stay the same and can change as we age. Research indicates that factors like declining physical activity and underlying heath conditions such as cardiovascular disease or respiratory illness can make an allergic reaction worse.

“An allergy that caused mild symptoms in your 40s may present very differently in your 60s,” says Dr. Kim. “Age-related changes to the immune system and the presence of other conditions can change how your body responds.”

An allergic reaction can happen fast and without warning. If you’ve noticed a pattern of repeated symptoms after eating a particular food, it’s important to see your doctor and not ignore it.

An allergist can confirm a diagnosis through testing, help identify triggers and advise on how to manage it, including whether carrying emergency epinephrine medication, like an EpiPen, is recommended. The earlier an allergy is properly diagnosed, the safer you can be.
