If you’ve been dealing with reflux, bloating, constipation, or even anxiety and can’t figure out why, histamines might be part of the picture. In this episode, I’m joined by Michelle Shapiro, RD, to break down the connection between histamine intolerance, MCAS, and gut symptoms and why so many people feel worse with standard gut protocols.

Michelle and I discuss:

• What histamine intolerance really is and how it overlaps with MCAS
• The wide range of symptoms histamine issues can cause (and why they’re often missed)
• How the gut, DAO enzyme, and microbiome influence histamine balance
• Why nervous system support is just as important as gut support
• Practical steps you can take if you suspect histamine intolerance

Michelle also shares her personal journey with histamines, mold exposure, and POTS and how slowing down and supporting safety in the body can be a turning point for healing.

Have you ever told yourself, “It’s not that bad , I’ll deal with it later” when it comes to your gut symptoms (or anything?)?

I get it because I did the same thing. For years, I brushed off my bloating, constipation, and fatigue, hoping they’d go away. But ignoring those whispers from my gut eventually led to bigger problems: SIBO, Hashimoto’s, a slowed metabolism, and histamine issues.

Here’s the truth: your symptoms aren’t random. They’re signals & your gut waving a red flag asking for support. When you ignore them, they snowball into more complicated issues that are harder (and more expensive) to fix down the road.

In this episode, I’m sharing:

• How ignoring “small” gut symptoms can turn into bigger health issues
• The snowball effect of reflux, constipation, bloating, and diarrhea
• Why functional medicine isn’t just about supplements
• My personal journey of what happened when I didn’t listen to my gut
• Why your symptoms are signals, not something to fear

And for the very first time, I’m offering something brand new: the Gut Health Audit.

👉 This is the most affordable way to get eyes on your case! Just $89! You’ll complete a comprehensive intake form, and I’ll personally review it to identify the gaps in your care, highlight patterns, and share your next steps. Whether that’s with us in gutTogether® or something totally different, you’ll finally have clarity on what to do next.

But spots are limited, only 20 spots are available (and as a podcast listener you're the first to hear about it!)

Have you tried all the gut-healing protocols, supplements, and diets, but you’re still constipated, bloated, or exhausted? You’re not alone, and the reason you’re stuck may not be what you think.

In this episode of the Love Your Gut podcast, I’m sharing the overlooked foundations that can make or break your gut healing journey. These aren’t the flashy, “quick-fix” solutions you see all over social media, but they’re the simple, powerful pieces that actually help your gut recover.

Here’s what you’ll learn:

• Why eating the same 5–10 foods can cause dysbiosis, leaky gut, and food reactions.
• How mineral depletion keeps you stuck in a cycle of low energy, hormone imbalances, and poor motility.
• Why low stomach acid, enzyme output, and bile flow can trigger infections like H. pylori and recurrent SIBO.
• The connection between nervous system dysregulation and low secretory IgA, reflux, and constipation.
• Practical steps you can start using today to finally support your gut the way it needs.

If you’ve been “doing everything right” and not feeling better, one of these missing pieces may be the reason.
