Behind the Scenes of Autoimmunity: What’...

In this episode of the School of Doza podcast, we go behind the scenes of autoimmunity to explore what’s really triggering your symptoms. From past infections to gut dysfunction, vitamin D deficiency, adrenal overload, and genetics—this episode unpacks the root causes that conventional medicine often overlooks.

• Most autoimmune disorders are connected to previous infections, including viruses and bacteria.
• A damaged gut barrier can trigger immune dysregulation—leaky gut is real.
• Vitamin D isn’t optional: low levels suppress the immune system’s ability to respond.
• Chronic stress and overactive adrenals can drive autoimmune flare-ups.
• Genetic variants like MTHFR may increase susceptibility to autoimmune conditions.

The Good Poops Challenge is an 8-week reset designed to support your gut, liver, and gallbladder—key systems often disrupted in autoimmune conditions. As discussed in this episode, improving digestion is foundational for reducing inflammation and supporting immune resilience.
