What are common eczema triggers?

Dr. Lawrence T. Chiaramonte, MD
Allergist & Immunologist

There are different causes and triggers of eczema. The role of some airborne allergens in eczema is unclear, but there seems to be good evidence for that of dust mites and possibly other household allergens. Symptoms can be aggravated by heat and stress. Exposure to animals, animal-derived fabrics such as wool, and feathers can set off the itching.

In sensitive individuals, foods may have an effect, even if there is no other diagnosed food allergy. As with other food allergies, eggs, milk, peanuts, soy, wheat, or fish are the likely culprits with eczema, but other foods may also be at fault. If food is suspected, the physician may supervise removing the suspected foods from the diet for a trial period.
