Eczema/Dermatitis Root Cause Protocol

Eczema (atopic dermatitis) affects more than 31 million Americans, many of them children. It causes red, itchy, dry patches, often in the elbow and knee creases, face and hands. In childhood, eczema often comes before food allergy, asthma and hay fever (the "atopic march"). At its core eczema is a barrier problem: many people carry changes in the filaggrin gene, so the skin lets irritants in and water out. Repairing the barrier with moisturizer is the foundation. Gut-skin connection: people with eczema often have a different gut microbiome, and some probiotic strains (especially L. rhamnosus GG) reduced eczema in some trials, mainly when started in pregnancy or infancy; results vary. Food: in a subset, especially young children, foods like milk and eggs drive flares. IgE testing with an allergist helps, but results do not always match symptoms; IgG testing is not validated. A careful elimination and reintroduction trial is the most useful test, and in children it should be done with their clinician. Staph bacteria: most people with eczema carry staph on their skin, which worsens flares. Dilute bleach baths lower it and are recommended by dermatologists. Steroid creams calm flares well but are best used in short courses. Tacrolimus and pimecrolimus are non-steroid options for thin skin. Biologics such as dupilumab help many people with moderate to severe eczema; eye irritation is the main side effect. Evening primrose and borage oil have not shown clear benefit in a Cochrane review. Breaking the itch-scratch cycle matters: moisturize, use cold compresses, keep nails short. Many children outgrow eczema, while some continue into adulthood. Steady care of the barrier, triggers, gut and stress gives the best long-term control.
