A SIBO Dietitian Who's Been on the
Other Side of the Breath Test
If you've been diagnosed with SIBO, you already know how isolating it gets. The bloating that shows up no matter how clean you eat, the round of antibiotics that worked until it didn't, the sense that you're managing a problem instead of solving it. Most of my SIBO clients have been through all of that before they find me.
I understand it from both chairs. Early in my career, working as a dietitian at Cedars-Sinai, I became a patient of Dr. Mark Pimentel and was one of the first people to take the hydrogen breath test for SIBO. So when I tell you SIBO is treatable and that the goal is more than symptom control, I'm not reading it out of a textbook.

Why SIBO keeps
coming back
Here's the issue: SIBO is rarely just about the bacteria. It's about why the bacteria overgrew in the first place. Motility, the way your small intestine sweeps food and bacteria through, is often part of the story. If that sweeping slows down, bacteria sit and ferment, and that fermentation is what you feel as bloating and gas. Treat the overgrowth without addressing the underlying cause, and it can return. That's why my work with you starts with understanding your individual physiology and history, not handing you a generic protocol.
How I work with
SIBO clients
We map your symptoms, your history, and what's actually driving the overgrowth. From there we build a plan that may include a structured low-FODMAP approach during treatment, a clear reintroduction phase so you're not restricting forever, and the diet and lifestyle pieces that support motility long-term. You'll understand the why behind every step, because people follow a plan they understand and abandon rules that feel arbitrary. Sarah Mirkin, RDN, CPT, LD is a Monash-certified low-FODMAP dietitian with over 25 years of experience and the author of The Beginner's Guide to Low-FODMAP. Sessions are virtual and available nationwide, with in-person options in Beverly Hills and Palm Beach.
