In this episode, Alyssa takes the conversation around hydrogen sulfide SIBO one level deeper. She shares how hydrogen sulfide SIBO is actually approached in practice, and why jumping ahead, whether to antimicrobials, binders, or protocols, often makes symptoms worse instead of better.

Rather than focusing on “what to take,” Alyssa breaks down the sequence that matters:

• Why clarity has to come before treatment
• Why symptom calming isn’t the same as healing (but still matters)
• Why motility, bile flow, and timing quietly determine whether progress sticks
  And why rebuilding the gut too early is one of the most common reasons people relapse

Along the way, she explains why hydrogen sulfide SIBO is so reactive, why some people feel better but flare easily, and why the same tool can help one person while flaring another, depending entirely on when it’s used.

Have you ever looked at your plate and thought, “I’m eating less than ever… so why is my weight going up?” If you’ve tried low-FODMAP, cut sugar and carbs, cleaned up your diet, and somehow feel heavier, slower, and more inflamed, this episode is for you.

In this episode, Alyssa dives into one of the most confusing and overlooked patterns in gut health: why some people with SIBO experience weight gain instead of weight loss, and why everything you’ve been told to do might actually be working against you. Alyssa explains why not all SIBO behaves the same, and how a specific subtype can quietly change how your body handles food, energy, and inflammation.

You will learn:

• Why common SIBO advice often doesn’t apply to this pattern
• What it means when your body seems to “hold onto” weight
• Why digestion can feel heavier and more reactive the harder you try
• Where diet helps, and where it can quietly backfire
• What needs to be addressed for real progress to happen

In this episode of The Gut Health Dialogues Podcast, Alyssa Simpson sits down with her client Doug, who shares his powerful journey from being house-bound and limited to a “safe” diet of chicken and rice, to reclaiming his gut health, his confidence, and his life.

What started as a frustrating case of “IBS with no answers” turned out to be Hydrogen Sulfide SIBO, a form of small intestinal bacterial overgrowth that’s often missed on standard breath tests and misdiagnosed as IBS, anxiety, or stress.

Alyssa and Doug unpack what it really takes to identify and treat this overlooked condition, from testing and dietary strategy to motility support and rebuilding tolerance, showing that recovery is not only possible, it’s life-changing.

What You’ll Learn

• How Hydrogen Sulfide SIBO differs from other types of SIBO.
• Common but often missed symptoms include bloating and diarrhea, fatigue, brain fog, and joint pain.
• The real reason restrictive diets often make things worse.
• Steps to test, identify, and treat Hydrogen Sulfide SIBO effectively.
• A firsthand look at what long-term gut healing and food reintroduction actually look like.

In this episode, Alyssa Simpson unpacks a common yet widely misunderstood subtype of small intestinal bacterial overgrowth (SIBO): hydrogen sulfide SIBO. Many people with this pattern have spent years chasing answers, trying diets like low FODMAP, gluten-free, or low-carb, cycling through symptom management, and being told tests are normal, only to feel worse, confused, or convinced there’s no solution in sight.

Alyssa breaks down:

• What hydrogen sulfide SIBO is and isn’t
• Why it behaves differently than hydrogen or methane dominant SIBO
• Why symptoms can be unpredictable, systemic, and not limited to the gut
• How conventional testing and treatment often miss it
• How to think about diet, testing, and targeted functional approaches

If you’ve ever felt like your digestive symptoms just don’t make sense, fluctuating between diarrhea, constipation, bloating, brain fog, fatigue, or body pain, this episode will help you finally connect the dots.

Have you tried low FODMAP, gluten-free, dairy-free, or elimination diets and still feel sick after eating? In this episode, Alyssa Simpson breaks down one of the most confusing and misunderstood nutrition strategies in gut health: the low sulfur diet.

This is not an episode about cutting out “bad foods” or following another restrictive diet forever. Instead, Alyssa explains why a short, strategic low-sulfur diet trial can be a powerful clarity tool for people who feel deeply unwell after eating, especially those who have already tried low FODMAP, gluten-free, dairy-free, or elimination diets with little to no relief.

She walks listeners through what sulfur actually is, why the body normally needs it, and why some people suddenly stop tolerating sulfur-rich foods that are otherwise considered healthy. Along the way, Alyssa shares real client stories that reveal how sulfur overload and hydrogen sulfide activity in the gut can explain symptoms that feel random, cyclical, or impossible to predict.

What you’ll learn in this episode:

• When a low-sulfur diet trial makes sense (and when it doesn’t)
• Common high-sulfur foods to temporarily reduce
• Low-sulfur foods that are often easier to tolerate during the trial
• Why protein does not need to be eliminated
• Supplements that may quietly increase sulfur load
• Why improvement during the trial is a clue, not a diagnosis
• How breath testing can help confirm hydrogen sulfide involvement

Eating out with food allergies, celiac disease, IBS, or food sensitivities can feel overwhelming — and sometimes unsafe. In this episode, Alyssa Simpson chats with Dylan McDonnell, founder of Foodini, about how technology and regulation are finally making restaurant dining safer and more transparent.

Dylan shares his personal experience growing up with celiac disease and how it inspired him to create Foodini: a platform that gives diners real ingredient and allergen data so they can confidently choose what’s safe to eat. They discuss why food allergies are rising, why restaurants struggle with allergen accuracy, and how new laws in California could change the future of dining nationwide.

Watch to learn:

• Why food allergies and intolerances are becoming more common
• Why restaurant menus are so hard to trust
• How personalized allergen-safe menus work
• What the new California food allergy law means for diners
• How to advocate for safer, more inclusive dining

Guest Bio: Dylan McDonnell is the founder and CEO of Foodini, the dietary intelligence company that helps power personalized menus for the 173m Americans with a food allergy or dietary need. A corporate lawyer by trade, he was diagnosed with celiac disease as a child, and has spent the last number of years advocating for increased transparency regarding what is in the food that we eat.

The holidays are the most wonderful time of the year. But for many people, they’re also a perfect storm of stress, irregular routines, rich meals, travel, and unpredictable digestion.

In this episode, Alyssa sits down with Dr. Joy Ostroff, a Hawaii-based naturopathic doctor with over three decades of clinical experience, for a powerful conversation on the REAL root causes of stubborn weight that diets never address.

Dr. Joy explains why weight struggles are rarely about willpower or calories and are almost always linked to deeper imbalances in the gut, hormones, detox pathways, and nervous system. She breaks down how issues like candida overgrowth, biofilm formation, yeast-driven sugar cravings, inflammation, and toxic burden interfere with metabolism and make weight loss nearly impossible, no matter what you eat.

This episode is a must-listen for anyone who has struggled with stubborn weight, recurring cravings, chronic bloating, fatigue, or feeling “stuck” in their health journey.

About Dr. Joy Ostroff: 

Dr. Diana Joy Ostroff is a Naturopathic Doctor & Traditional Chinese Medicine practitioner with 34 years in holistic health. Founder of the Center for Natural Healing Hawaii and author of the Wisdom of Well-Being series, she blends science, experience, and integrative care to help patients feel their healthiest and happiest.

In this episode, Alyssa unpacks a connection that many people don’t realize is at the heart of their gut health struggles: the tight interplay between constipation, liver overload, and sleep disruption.

If you wake up between 1–3 AM, feel sluggish, bloated, or totally backed up the next day, this episode is for you. In this episode, Alyssa explains the powerful (and often overlooked) link between constipation, liver stress, and sleep disruption, and how real food and simple rituals can help break the cycle.

What you’ll learn in this video:

• Why constipation isn’t just a digestion issue and why it can overload your liver, disrupt detox, and mess with your sleep.
• How poorly timed or “healthy-but-not-helpful” meals (like super high fiber or too-light dinners) make things worse.
• The three-part framework Alyssa calls Relax, Release, Replenish, and how to eat to relax your nervous system, gently release waste, and replenish vital nutrients.
• Simple, doable evening meal and snack ideas to support motility, liver detox, and stable blood sugar overnight.
• A no-supplement-needed food strategy that can help your body reset over time.
