By Mayo Clinic staffComplications of food allergy can include:
- Anaphylaxis, a life-threatening allergic reaction.
- Atopic dermatitis (eczema). About one in three people with atopic dermatitis also have a food allergy.
- 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.
