It is important to realise that the skin is an immune barrier like the gut. Eczema is a sign of inflamed skin which is a sign that the gut has become inflamed and overly porous. This is also known as a leaky gut. When the gut is leaky, it allows undigested foods, bacteria, yeast, and other pathogens in to the bloodstream. This triggers an immune response, inflammation and histamine release which can show up as eczema.
