Complications

By Mayo Clinic staff

Complications of food allergy can include:

  • Anaphylaxis. This is a life-threatening allergic reaction.
  • Atopic dermatitis (eczema). Food allergy may cause a skin reaction, such as eczema.
  • Migraines. Histamines, released by your immune system during an allergic reaction, have been shown to trigger migraines in some people.

While some people think food allergies are linked to childhood hyperactivity and to arthritis, there's no evidence to support this.
