The Link Between Food Allergies, Food Sensitivities, and AD
The skin barrier becomes impaired in people who have AD. Once this happens, sensitivity increases not only to environmental allergens but also to food allergens, says Schweta Arakali, MD, an allergist at the Center for Allergy and Asthma Care in Allentown, Pennsylvania.
Even if you don’t have a food allergy — which causes reactions that can include hives or anaphylactic shock, among other possible symptoms — you can still have a food sensitivity.
“If you’re sensitive to a food, you may have worsening existing eczema patches, or you may notice your skin feels itchier overall,” says Marisa Garshick, MD, a clinical assistant professor of dermatology at Weill Cornell Medical College and a dermatologist at MDCS Dermatology in New York City. You may also develop a rash or have an upset stomach or diarrhea after you eat certain foods, she says.
It can be challenging to pinpoint a food sensitivity. Unlike a true allergy, which tends to cause a reaction right away but can take up to two hours, a food sensitivity reaction may take up to three days before you notice any symptoms.
“Some people might get [food sensitivity] symptoms within minutes to hours,” says Danilo C. Del Campo, MD, a dermatologist at Chicago Skin Clinic. “For other people, it might be a couple days after.” Once a food sensitivity reaction occurs, it could persist for days or even weeks, he says.
