Atopic March

Atopic march is the progression of immune-mediated conditions that appear when the microbiome does not properly train the infant immune system. The article links missing core Bifidobacteria and excess pathogenic bacteria to inadequate immune training for allergen tolerance. Eczema by 3–6 months is described as the earliest clinical indicator of incorrect infant immune priming. The article lists eczema, food allergies, asthma, type 1 diabetes, Crohn's, ADHD, autism, and obesity as conditions in the immune dysfunction timeline.
