The Mel Robbins PodcastWhy 80% of Autoimmune Diseases Happen to Women & Solutions From a Renowned MD
CHAPTERS
Why autoimmune disease (especially in women) is exploding—and what this episode will give you
Mel explains why a short clip about women and autoimmunity went viral and why they’re doing a deeper masterclass. She introduces Dr. Sarah Szal and frames the episode as an empowerment-focused, low-cost, lifestyle-driven roadmap.
- •80% of autoimmune diseases occur in women and the topic struck a nerve online
- •Promise: understand causes, symptoms, and practical solutions that often cost nothing
- •Introduction of Dr. Sarah Szal’s background (Harvard/MIT, UCSF, integrative medicine)
- •Goal: leave listeners informed, empowered, and able to take action
Lifestyle medicine: treating the ‘how you got here,’ not just the diagnosis
Dr. Szal defines lifestyle medicine and contrasts it with the typical diagnose-and-prescribe approach. She sets the stage for how lifestyle factors can prevent or even reverse many chronic disease patterns.
- •Lifestyle medicine focuses on sleep, food, movement, stress, connection, and emotions
- •Addresses upstream causes instead of only symptom suppression
- •Claim: lifestyle accounts for a large share of prevention/reversal potential
- •Three outcomes: more energy, better regulation/sense of safety, empowerment
Autoimmunity 101: the immune system’s ‘mistaken identity’ and autoantibodies
They define autoimmune disease as an immune imbalance where the body attacks its own tissue. Dr. Szal explains autoantibodies as measurable markers of this internal ‘civil war.’
- •Immune system as ‘private security’ that gets confused
- •Autoimmune disease = attack on normal tissue + autoantibodies + matching symptoms
- •Autoantibodies can be present for years before diagnosis
- •Why many people go undiagnosed for 7–14 years
What counts as autoimmune: classic diseases vs. autoimmune-adjacent conditions
Dr. Szal lists common classic autoimmune diseases and highlights how many conditions fly under the radar as autoimmune. She also broadens the lens to conditions with autoimmune features like endometriosis and long COVID.
- •There are 100+ classic autoimmune diseases (RA, Hashimoto’s, MS, type 1 diabetes, psoriasis, celiac)
- •Psoriasis as a common but often misunderstood autoimmune condition
- •Autoimmune-adjacent: endometriosis, some IBS forms, chronic Lyme, long COVID
- •Knowing it’s autoimmune helps focus on root-cause investigation
The rise in autoantibodies: what’s changing (and it’s not genetics)
They discuss how anti-nuclear antibodies (ANAs) have nearly tripled over 25 years, pointing to environmental and lifestyle shifts. Dr. Szal emphasizes triggers and exposures as the key drivers behind the surge.
- •ANAs rising dramatically suggests widespread immune dysregulation
- •Genetics haven’t changed—environment and lifestyle have
- •Suspects: food system changes, stress load, trauma burden
- •Sets up the ‘root causes’ framework that follows
The 3 root causes: genetic predisposition, leaky gut, and triggers
Dr. Szal presents a widely cited triad required for autoimmune disease: genetics, intestinal permeability, and a trigger. The trigger category includes trauma/toxic stress and major hormonal transitions.
- •Three requirements: genetics + leaky gut + trigger
- •Triggers can be trauma/toxic stress or hormonal transitions (pregnancy/postpartum/perimenopause/menopause)
- •Two of three are modifiable: gut integrity and triggers
- •Framework for prevention, reversal, and personalized plans
Leaky gut explained: ‘loss of a boundary’ and why the immune system flares
They unpack what leaky gut means biologically (tight junction dysfunction) and why it matters immunologically. Because most immune activity sits near the gut, permeability can provoke inappropriate immune activation.
- •Tight junctions should form a strong intestinal barrier
- •Permeability allows particles/foods/microbes to cross and provoke immune response
- •70–80% of the immune system is located along the gut
- •Leaky gut as both a physical and symbolic ‘boundary’ issue
Top triggers: trauma, toxic stress, and hormones (especially pregnancy)
Dr. Szal names trauma as the leading trigger she sees clinically and in research. She also describes pregnancy as a major immune adaptation event that can precipitate postpartum autoimmune problems in vulnerable people.
- •Trauma/toxic stress often precede autoimmune onset
- •ACEs (abuse/neglect) commonly correlate with autoimmunity in patients
- •Pregnancy requires immune tolerance to ‘foreign’ DNA; can misfire
- •Hormonal change is a large trigger category across the lifespan
Why medicine misses it: pharma-influenced training and the missing lifestyle toolkit
Mel presses why autoimmunity and root-cause lifestyle strategies aren’t emphasized in training. Dr. Szal argues the system is oriented toward diagnosis and pharmaceuticals, while lifestyle medicine is crucial earlier in the disease continuum.
- •Medical training often defaults to diagnose + prescribe
- •Lifestyle medicine isn’t well taught despite effectiveness for early-stage disease
- •Some conditions still require meds (e.g., advanced type 1 diabetes)
- •Dr. Szal’s personal ‘wake-up call’ and self-education journey
What worsens leaky gut fast: alcohol, chronic stress, and circadian disruption
They identify alcohol as a powerful driver of intestinal permeability and explain how stress hormones can ‘poke holes’ in the gut barrier. Night shift work and circadian disruption are linked to higher autoimmunity risk via metabolic and mitochondrial effects.
- •Alcohol directly damages tight junctions (common lab model for leaky gut)
- •Excess stress triggers CRH/cortisol pathways that increase permeability
- •Hard training can transiently increase leaky gut; chronic overload matters
- •Night shifts/circadian disruption linked to higher autoimmune risk
Why women are hit harder: biology plus culture, caregiving load, and research gaps
Dr. Szal distinguishes sex-based biology from gender-based social factors and argues the latter are underappreciated drivers. They discuss the measurable health cost of overfunctioning, burnout, and the systemic gaps in women’s healthcare research and treatment.
- •Women have ~4x autoimmune rates; MS rising disproportionately in women
- •Contributors: X chromosome + higher trauma/stress exposure + hormones
- •Caregiving/overfunctioning and difficulty saying no are measurable stressors
- •Gender bias and research gaps (male-default evidence) worsen outcomes
Gabor Maté clip unpacked: people-pleasing, repressed anger, and chronic stress pathways
Mel plays a viral clip summarizing traits seen before autoimmune onset—over-responsibility, duty-first identity, niceness, and suppressed boundaries. Dr. Szal explains why it resonates: cultural norms can keep women dysregulated and sick.
- •Patterns: prioritizing others’ emotional needs, duty-first identity, repressed anger, fear of disappointing
- •Chronic stress undermines immunity and can trigger autoimmunity
- •Framing: cultural programming more than individual ‘weakness’
- •Validation: naming these norms helps people reclaim agency
ACEs and the PINE Network: how childhood adversity rewires stress, immunity, and hormones
They review the ACE questionnaire and connect early adversity to later chronic disease risk, including autoimmune disease. Dr. Szal introduces the PINE Network (Psychology–Immune–Neurological–Endocrine) to explain lifelong dysregulation patterns.
- •ACE score correlates with risk for 45 chronic diseases, including autoimmunity
- •PINE Network describes coupled systems shaped by early stress
- •Dysregulation may show up as immune imbalance, cortisol issues, anxiety/low HRV
- •Key concept: safety in childhood calibrates lifelong physiology
Recognizing symptoms (and why they’re ‘non-specific’): when to seek testing
Dr. Szal lists common cross-cutting autoimmune symptoms and explains why diagnosis is often delayed. They highlight Hashimoto’s prevalence markers and recommend seeing a primary care clinician with clustered symptoms, escalating to specialists as needed.
- •Common symptoms: fatigue, inflammation, swelling, joint pain/aches
- •Organ-specific symptoms: neuropathy, gut issues, rashes, mood changes, visual changes
- •13% of ‘healthy’ people may have thyroid antibodies (Hashimoto’s risk signal)
- •Rule of thumb: 3+ symptoms → start evaluation; specialist based on dominant system
Immediate action plan: testing, elimination diet, and tracking triggers
Mel asks for the most important next steps, and Dr. Szal delivers a simple triad: test, eliminate common trigger foods, and identify/track triggers (including trauma). She provides a practical list of labs and a free path if testing isn’t accessible.
- •Three steps: get tested, do an elimination diet, hunt/track triggers
- •Suggested labs: CBC w/diff, hs-CRP, ESR, NLR; plus glucose/insulin and hormones
- •Vitamin D highlighted for gut/immune integrity
- •If no testing: start elimination diet immediately (free)
The 3-week elimination diet and ‘locus of control’: small changes that shift physiology
They outline removing gluten, dairy, sugar, and alcohol for three weeks and tracking symptom changes. The discussion reframes lifestyle choices as a controllable lever that can reduce dysregulation even when life stressors remain.
- •Remove gluten/dairy/sugar/alcohol for 3 weeks; track fatigue, joints, skin, energy
- •Diet as ‘bringing the outside world inside’—boundary-supportive or boundary-breaking
- •Some may need longer than 3 weeks, but early signal often appears quickly
- •Hope message: incremental shifts compound into major transformation
Regulating the body to heal trauma: breathwork (5.5 in/5.5 out) and embodied safety
Dr. Szal emphasizes breath as an underused tool to create safety and downshift stress physiology. They practice three breaths together and connect regulation practices (breath, yoga, meditation, somatic work) to improved immune balance and healing capacity.
- •Shallow chest breathing signals danger; slow abdominal breathing signals safety
- •‘Rule of fives’: ~5.5 seconds in and out for several minutes (or even 3 breaths)
- •Regulation as prerequisite for trauma resolution and immune stability
- •You can’t ‘think’ your way out of trauma—somatic approaches matter
Specific conditions spotlight: Hashimoto’s and POTS (what they are and how to evaluate)
Mel asks about trending diagnoses, and Dr. Szal explains Hashimoto’s as autoimmune thyroid attack and clarifies its role in most hypothyroidism cases. They also cover POTS, its connection to autonomic dysfunction and long COVID, and how it’s tested clinically.
- •Hashimoto’s: autoimmune thyroid disease; symptoms include fatigue, weight gain, dry skin/hair, eyebrow thinning
- •Diagnosis: thyroid labs + thyroid autoantibodies
- •POTS: orthostatic intolerance with tachycardia/lightheadedness/fainting
- •Evaluation: lying/sitting/standing pulse & BP; lifestyle supports include salt/electrolytes and addressing insulin resistance
Closing: integrate meds + lifestyle, resolve trauma, and reclaim control of your health
Dr. Szal explains lifestyle medicine as ‘added value’ alongside pharmaceuticals, potentially reducing medication needs under supervision. They end with a clear call: address trauma, build regulation, and remember it’s easier to live in safety than dysregulation.
- •Integrative approach complements (not replaces) appropriate medications
- •Lifestyle changes can sometimes reduce dose or need for meds with clinician guidance
- •Most important action: assess and resolve trauma by creating safety in the body
- •Final message: regulation sends healing cues to immune, nervous, and endocrine systems
