• What Methane SIBO actually is and how it’s different from hydrogen SIBO
• Why it causes bloating, constipation, and sluggish digestion
• How stress, surgeries, and medications set the stage for overgrowth
• Why standard tests often miss methane overgrowth
• What testing options and diet changes can help you finally move forward

You’ll walk away understanding the “why” behind your symptoms and the first steps to start healing.

In this episode, Alyssa Simpson is joined by Nikki D’Agostino, a nervous system retraining specialist, to dive deep into Primal Trust, a program built on neuroplasticity, somatic practices, and trauma healing. They explore how chronic stress, limbic system impairment, and unconscious trauma can lock your body and brain into survival mode, interfering with digestion, nutrient absorption, immune function, and overall healing.

You will get clarity on:

1. Why gut healing often stalls unless you also address the nervous system
2. How trauma (big or subtle) can embed in your body and alter stress patterns
3. The structure of Primal Trust’s programs (Regulate, Level 2, Level 3)
4. Practical tools like V-breath, pattern interrupts, somatic orienting, and daily “nervous system reset” techniques
5. What kind of changes you might begin to notice, and in what timeframe — and how to integrate this healing work into daily life

Guest Bio:

Nikki helps clients heal from mold illness, anxiety, depression, food sensitivities, emotional regulation issues, and chronic stress through neuroplasticity therapy. She guides them to rewire the limbic system, regulate a maladaptive stress response, and shift the brain-body connection from survival to repair. Her unique blend of somatic practices + brain retraining gives listeners a fresh lens on what true healing might look like beyond diets and supplements.

In this episode, Alyssa Simpson breaks down one of the most confusing gut health struggles: why nourishing foods like vegetables, lentils, or garlic can suddenly trigger bloating, gas, cramping, or flare-ups.

Alyssa explains the surprising reasons behind this — from gut inflammation and bacterial overgrowth (like SIBO) to histamine intolerance, food sensitivities, and sluggish digestion. More importantly, she shares practical, hope-filled strategies you can use right now to calm your symptoms and start building a more resilient gut.

You’ll learn:

• Why high-fiber “gut healthy” foods can backfire during a flare
• How bacterial fermentation (FODMAPs, SIBO, and dysbiosis) leads to gas, bloating, and urgency
• The role of histamine intolerance, food sensitivities, and inflammation in food reactions
• Pantry staples that could be secretly making your symptoms worse (like cinnamon, bone broth, and leftovers)
• A flare-friendly food list to calm your gut and reduce symptoms fast
• How to gradually reintroduce foods without fear using Alyssa’s “small plate strategy”
• The power of “veggie mash” to rebuild microbial diversity and expand your diet safely

If you’ve ever felt discouraged or stuck eating the same 10 foods because everything else makes you flare, this episode will help you see that healing is possible.

In this episode of The Gut Health Dialogues, Alyssa Simpson sits down with Dr. Diana Driscoll—optometrist, researcher, and author of The Driscoll Theory—to uncover connections between gut health, vagus nerve dysfunction, chronic inflammation, and conditions like POTS, SIBO, long COVID, and Ehlers-Danlos Syndrome.

Dr. Driscoll shares her journey from being incapacitated by illness to discovering root causes medicine often misses. She explains how vagus nerve dysfunction affects digestion, motility, blood flow, and brain chemistry—and why real healing goes beyond symptom management.

Key topics:

• Why vagus nerve dysfunction is the “missing link” in gut and autonomic issues
• The role of histamine, inflammation, and oxidative stress in driving symptoms
• How POTS, SIBO, EDS, and long COVID overlap through nervous system dysfunction
• Upper vs. lower GI motility—and why both matter for SIBO recovery
• Hopeful starting points for those living with chronic illness

Dr. Driscoll also shares practical strategies, including how supplements like Parasym Plus® and NAC Max (links below) can support vagus nerve function, brain chemistry, and overall healing.

This episode is a must-listen if you’ve been searching for answers to gut issues, unexplained fatigue, POTS, or connective tissue disorders and need validation that you’re not “crazy” or alone.

If you’ve tried more fiber, magnesium, MiraLAX, and water—but you’re still backed up—this episode is for you. Alyssa dives deep into constipation, busts myths, and shows what really moves the needle when your gut is sluggish. She covers why “healthy” foods can sometimes make things worse, what your gut actually needs to start moving, and small shifts in timing, hydration, and food pairings that can bring real relief.

What you’ll learn in this episode:

• Which foods (even “healthy” ones) can slow down digestion, especially when your gut is already struggling.
• How to use cooked veggies, soluble fiber, and hydration strategically so your supplements or laxatives don’t work against you.
• Why pairing fiber without sufficient water or spacing supplements and meals properly can backfire.
• Simple daily habits — like eating schedule, gentle movement, chewing more — that support motility (your gut’s “get moving” power).
• How imbalances like methane overgrowth or yeast (candida) might be silently sabotaging your progress if the basics aren’t working.

Histamine intolerance might feel like the final answer, but what if it’s really just the tip of the iceberg?

In this episode, Alyssa sits down with Jennifer Fugo, MS, LDN, CNS — a clinical nutritionist and host of the Healthy Skin Show — to uncover the real root causes behind histamine intolerance and chronic skin issues.

They uncover why antihistamines don’t always help, why low histamine diets often fail long-term, and what hidden root causes could be driving your symptoms instead. From gut infections and parasites to thyroid issues and skin dysbiosis, they dig into the overlooked triggers that keep people stuck in flare cycles.

They also talk about the surprising gut-brain-skin connection, why stool tests often miss what’s really happening, and the steps you can take to move toward true resilience and food freedom — not just restriction and supplements.
