If you’re in perimenopause and suddenly feel inflamed, reactive, bloated, tired, or sensitive to foods that never bothered you before, this episode is for you.

In this conversation, Michelle and Tabitha sit down with Dr. Atoosa Kourosh, a board-certified physician in pediatrics, allergy & immunology, and a leader in integrative medicine, to explain why midlife can feel like your body is turning against you — and what’s actually happening behind the scenes.

Dr. Kourosh breaks down how hormonal shifts in perimenopause interact with the gut microbiome and immune system, leading to inflammation, autoimmunity, histamine issues, and “new” sensitivities in women who were previously healthy and resilient.

This episode goes beyond “just hormones” to explain the root causes — and what a more complete, personalized approach can look like.

In this episode, we cover:

• Why perimenopause often triggers inflammation, immune changes, and autoimmune flares
• What “loss of immune tolerance” means — and why foods, stress, and the environment can suddenly feel overwhelming
• How gut microbiome disruption plays a central role in midlife symptoms
• The connection between histamine intolerance, allergies, and perimenopause
• Why “just taking a Zyrtec” doesn’t address the root cause
• How nutrigenomics (genetic testing) can personalize hormones, supplements, detox pathways, and even exercise
• Why some women feel worse on hormone therapy — and how genetics can explain it
• Mold, toxins, antibiotics, and other hidden triggers that can amplify symptoms
• What to test before going gluten-free (including celiac screening)
• Simple, practical gut-supportive steps you can try now while you wait for answers

If you’ve been told:

• “This is just part of aging”
• “Your labs are normal”
• “It’s stress”
• “Just push through it”

This conversation will help you understand why your symptoms are real, why perimenopause can last 10–15 years, and why you don’t have to accept feeling miserable in this season of life.
