Virtual SIBO &
Low-FODMAP Dietitian
You don't have to live near Beverly Hills or Palm Beach to get real help with your gut. Most of the clients I work with are on a screen, not in my office, and the results are exactly the same. A video session where we actually dig into your symptoms, your labs, and your triggers works just as well as sitting across from each other in a room. What matters is the protocol, not the zip code.
If you've been Googling "SIBO dietitian virtual" or "low FODMAP dietitian" at 11pm because your stomach won't calm down and your last doctor's appointment ended with "just try cutting out gluten," you're in the right place. I'm Sarah Mirkin, RDN, CPT, LD — Monash University certified in the low-FODMAP diet, which is the actual gold standard for this work, not a certificate you can get in a weekend. I've been doing this for 25+ years.
Why Virtual
Works
Here's the issue: SIBO and IBS aren't conditions you fix in one appointment. They're conditions you manage through phases — elimination, reintroduction, personalization — and what actually moves the needle is consistency and access, not geography. A client in Chicago who can hop on a video call every two weeks and text me when a new symptom shows up is going to get further than someone who has to drive 45 minutes for an in-person visit they can only make once a month.
I see clients virtually nationwide, alongside the Beverly Hills and West Palm Beach practices. Video sessions let us go through your food logs together in real time, adjust your reintroduction schedule the moment something flares, and stay in closer contact between visits than most in-person practices allow.
What I Actually Do
Differently for SIBO
Most people land on a low-FODMAP diet because someone told them to "cut out gluten and dairy" and it sort of worked, sort of didn't. That's usually because IBS symptoms and SIBO symptoms look nearly identical from the outside, but the underlying cause is different, and treating the wrong one keeps people stuck in the same cycle for years.
I work alongside your gastroenterologist for testing and treatment planning, then guide you through the three actual phases of the low-FODMAP diet along with dietary protocols aimed at helping prevent SIBO from coming right back after treatment. That last part is where a lot of people get burned: they treat the SIBO, feel better for a few weeks, and then it returns because nothing changed about how they were eating. The protocol has to outlast the treatment.
Most clients start feeling meaningfully better within about 4 days once the elimination phase is being followed correctly. The full process — elimination, reintroduction, personalization — usually takes 3 to 6 months for results that actually last, not just a short-term fix.
"I was at a loss about what was going on with my body and spent months trying all kinds of diets — vegetarian, high fiber, raw, liquid. Nothing was helping. When Sarah introduced me to low FODMAP it all began to make sense."
That's the pattern I see constantly. It's rarely that someone hasn't tried hard enough. It's that they've been guessing without a structured, personalized protocol behind them.
Digestive Issues and
Weight, Together
If you're also dealing with weight that won't budge on top of the gut symptoms, that's not a coincidence, and you don't need to pick one problem to work on first. Digestive issues and weight often go hand-in-hand — bloating, inflammation, and how well you're absorbing nutrients all affect each other. The combined approach addresses both at once instead of treating them as two separate projects.
What Working Together
Looks Like
No, you don't need to live in Beverly Hills or Palm Beach. Sessions may be billed to insurance when applicable, and I work with some PPO plans and can provide superbills for out-of-network reimbursement if you're not in-network. Whether you're in Chicago, Seattle, or Palm Beach, the process is the same video-based, structured approach.
