Delayed Food Allergy Symptoms

Food allergies that do not show symptoms right away are called "delayed food allergies." Symptoms of these types of allergy include: chronic headaches or migraines, canker sores, joint pain, and bowel problems among others. People with this type of allergy often have a positive result on allergy tests such as the ELISA IgG, but often rarely have one on the IgE skin prick test.

Fast Facts:

  • This type of allergy is often referred to as "hidden food sensitivity", or "delayed onset food allergy".
  • Food allergies are often misdiagnosed because it is hard to pinpoint the allergy to one specific food.
  • Removing foods that cause these symptoms is the main form of treatment.
