Gut Health and Migraines: Your Mother’s Migraines?

Gut health and migraines may be more connected than you’ve ever been told — and if you’ve been waiting for your migraines to “just go away” after menopause, this episode might change everything. 

Migraines are now being viewed as a symptom of deeper dysfunction in the brain, gut, mitochondria, and vascular system — not just a hormonal inconvenience. 

If you’re tired of powering through, relying on quick fixes, or wondering why nothing seems to work long-term, this episode gives you a smarter path forward. We might have been overlooking the missing link between gut health and migraines.

My Guest:

Dr. Amelia Scott Barrett is a Stanford-trained neurologist and founder of Migraine Relief Code, where she pioneers a precision medicine approach to chronic headaches and migraine. She created the first genetic testing panel designed specifically for people with migraine, helping patients identify their unique Genetic Headache Type and follow customized recovery protocols that combine medical care, nutrition, supplements, and lifestyle strategies. A TEDx speaker and author of the upcoming book ALIGN: Live the Way You’re Wired to Relieve Headaches + Migraine for Good, her work has been featured in Business Insider and Women’s World. 

After launching her private neurology practice in Denver in 2003, she founded Migraine Relief Code in 2019 to bring personalized, science-driven solutions to people worldwide. Dr. Barrett is passionate about addressing migraine as a women’s health crisis, empowering women to relieve pain, protect their earning power, and reclaim their lives.

The 4 Core Systems Behind Migraines

• Brain Chemistry (Serotonin)

1. 1. • Estrogen directly impacts serotonin.
      • When estrogen drops → serotonin drops.
      • Serotonin influences:
      • Migraine signaling
      • Vascular tone
      • Gut function

• Vascular Regulation

1. 1. • Blood vessel dilation and constriction are tied to serotonin.
      • Migraine brains often have “jumpy” vessels.

• Inflammation & Gut Health

1. 1. • Serotonin helps maintain gut barrier integrity.
      • Estrogen decline affects:
      • Microbiome balance
      • Gut lining
      • Inflammation levels
      • Women already slightly compromised feel it more during hormonal shifts.

• Mitochondrial Energy Production

• • • Mitochondria = cellular batteries.
    • Impaired energy production can trigger migraines.
    • This area is gaining research traction.

Quick Fixes vs Root Cases

• Migraine is the leading cause of disability in women under 50.
• Overuse of medication can:
  • • Increase headache frequency
    • Reduce medication effectiveness over time
• Short-term fixes can lead to long-term worsening.

Why Migraines Are More Common in Women

• Migraines are 3x more common in women.
• Estrogen receptor gene plays a role but hundreds of other genes affect:
  • • Inflammation
    • Mitochondria
    • Brain chemistry
    • Vascular health
• Note that these apply to both men and women.
  
  

Why Gut Health and Migraines Worsen During Menopause Transition

Aging, Gut Health & Mitochondria

• Mitochondrial function declines with age.
• Toxin accumulation can impair energy production.
• If genetically poor at detoxification → higher impact.
• Gut issues may worsen over time:
  • • Gluten sensitivity
    • Dairy sensitivity
    • Leaky gut
    • Excess immune activation
• These are cumulative stressors.

Personalized Migraine Recovery

• Not every supplement or diet works for every person.
• Genetic insight can clarify:
  • • What foods help/hurt
    • Which medications work
    • What movement supports recovery
