447: Leaky Gut, SIBO, the Fiber Crisis and the Wellness Habits Quietly Causing Bloating with Dr. Karan Rajan

Dr. Karan Rajan is an NHS surgeon, gut health specialist, founder of LOAM, and host of the Dr. Karan Explores podcast. He joins the show to explain why so many people are constantly bloated, reacting to foods, and being told it’s “normal”—and what’s actually going on in your gut.

We break down the truth about “leaky gut,” the fiber deficiency epidemic, and how your microbiome is directly influencing your hormones, mood, and skin. Dr. Rajan also shares why many gut health trends are overcomplicated or misguided—from over-reliance on probiotics to restrictive protocols like low FODMAP—and what actually moves the needle when it comes to digestion.

You can find Dr. Karan Rajan on Instagram @drkaranrajan and on TikTok @dr.karanr.

We also get into:

• What healthy digestion actually looks like
• How often you should be going to the bathroom
• Common causes of bloating (including “healthy” foods)
• The gut–brain connection and anxiety
• How stress and hormones impact digestion
• Why fiber is one of the most overlooked tools in health
• The downside of probiotics for some people
• SIBO, elimination diets, and when they go too far
• Lemon water—does it actually help?
• Parasite cleanses, microbiome trends, and fecal transplants
• GLP-1 medications and gut health

If your gut feels off but you can’t figure out why—or you’ve tried everything and still feel stuck—this episode will give you clarity on what actually matters.
