In this concise educational monologue, Gary Brecka explains that roughly 80% of the immune system resides in the gut and constantly communicates with the skin via the gut‑skin axis. He cites studies showing that people with eczema commonly exhibit gut dysbiosis—characterized by reduced bacterial diversity and a loss of beneficial species such as Lactobacillus and Bifidobacteria. These microbes normally protect the gut lining, lower inflammation, and support the skin’s immune barrier. When the gut barrier is compromised, a leaky gut develops, allowing partially digested food, toxins, and microbes to enter the bloodstream and trigger a systemic immune response that manifests as eczema. Brecka concludes that without addressing gut inflammation and restoring a healthy microbiome, eczema cannot be fully healed.
