The Gut Show

You may have seen Bryan Johnson talking about autoimmune gastritis (AIG), but what is it actually, and what does the research say?

In this episode of The Gut Show, we're digging into autoimmune gastritis, including what happens in the stomach, symptoms, pernicious anemia, and what treatment actually looks like. We'll also take a closer look at some of the claims being shared online and separate what's backed by research from what might be getting a little ahead of the science.

If Bryan Johnson's story has you wondering about AIG or questioning whether you should be worried about it, this episode will help you understand what we actually know.

Can digestive enzymes help with IBS symptoms? What about enzymes that target specific FODMAPs?

In this episode of The Gut Show, we're talking with Jocelyn Wells from FODZYME about digestive enzymes and their role in breaking down FODMAPs.

We'll explore what digestive enzymes are, how they work, and how targeted enzyme therapy may help with digestion and IBS symptoms.

We'll take a closer look at enzymes designed to target specific FODMAPs, discuss whether using an enzyme supplement means you're actually deficient in that enzyme, and whether enzyme therapy can be effective when it doesn't target every FODMAP group.

If you're a clinician wanting FODZYME samples and resources for your practice, you can request them here.

In this episode, we cover:

Behind the scenes [1:53]

Today's guest [3:35]

What are enzymes? [4:39]

What are the different types of enzymes? [6:14]

If an enzyme works, does that mean you are deficient? [10:59]

Targeted enzyme therapy [17:57]

Specific enzymes for the different FODMAPs [22:07]

Inulinase [23:40]

How do these enzymes work? [28:24]

Is it a bad thing to not have that fermentation process? [31:18]

Does it actually work if it doesn't target all of the groups? [34:31]

Can we bypass this and just put these microbes in the gut? [40:28]

What do Ehlers-Danlos syndrome and hypermobility have to do with IBS? A lot more than you might think. In this episode, Rebecca Mass-Krajewski, Hypermobility & Ehlers-Danlos expert and I break down how connective tissue differences can impact the entire body—from digestion and motility to pain, sensitivity, and even the pelvic floor.

MCAS. POTS. Hypermobility. GI symptoms that don't quite fit the usual boxes. On this episode of The Gut Show, Dr. Alexis Cutchins joins us to unpack what cardiology has to do with GI—and why these systems are far more connected than most people realize. We dive into the emerging overlap between cardiology, gastroenterology, and immune-driven conditions, exploring why these patterns so often show up together, what red flags clinicians should be watching for, and why GI symptoms may actually start far beyond the gut—especially when dysautonomia, heart palpitations, dizziness, and persistent fatigue are part of the picture.
