Condition hub

Eczema, read through the systems beneath it.

Eczema (atopic dermatitis and related subtypes) understood through the functional-medicine lens: how the 8 systems may drive the skin presentation. Educational, hypothesis-framed, evidence-graded — not medical advice.

  • atopic
  • dyshidrotic
  • nummular

Each system below is explored specifically for eczema — the plausible mechanism, the literature graded A–D, and the functional tests worth discussing. Systems open as their evidence is synthesised and clears the human review gate; the rest are honestly marked coming soon rather than padded out.

The eight systems

How each may drive what you see.

01 Gut / Microbiome Dysbiosis, permeability, and the gut–skin axis. Available
02 Nutrient Status Vitamin D, zinc, and essential fatty acids. Soon
03 Hormones Androgens, thyroid, and insulin signalling. Soon
04 Stress / HPA Cortisol and the brain–skin axis. Soon
05 Detoxification / Liver Biotransformation and clearance load. Soon
06 Immune / Inflammation Th2 skew and barrier–immune crosstalk. Soon
07 Skin Barrier Filaggrin, lipids, transepidermal water loss. Available
08 Energy / Mitochondrial Cellular energy and oxidative stress. Soon

2 of 8 systems published so far; the rest as the evidence clears review.
