Boca Raton Dietitian
IBS, SIBO & Weight Management
Boca Raton attracts people who invest in their health and expect exceptional results. If you're dealing with chronic digestive issues or weight management that hasn't responded to standard care, the right specialist changes everything.
I'm Sarah Mirkin RDN, CPT, LD — a Registered Dietitian Nutritionist with over 25 years of clinical experience specializing in Irritable Bowel Syndrome (IBS), Small Intestinal Bacterial Overgrowth (SIBO), and sustainable weight management. Based in Palm Beach and serving Boca Raton clients virtually, I offer the level of personalized, evidence-based care that discerning clients deserve.
The Standard
You Should Expect
Most people — even in Boca Raton — have been through the same frustrating cycle. Physicians who offer limited answers for chronic digestive issues. Weight loss programs that work temporarily and then don't. Nutrition advice that ignores the complexity of your individual physiology, lifestyle, and goals.
That ends here.
Every client I work with receives a program built entirely around them. Not a template. Not a one-size-fits-all protocol. A genuinely personalized strategy developed from a thorough understanding of your history, your metabolism, your food preferences, and your life.
Specialized Expertise
in IBS and SIBO
Irritable Bowel Syndrome (IBS) and Small Intestinal Bacterial Overgrowth (SIBO) are among the most misunderstood conditions in modern medicine. Up to 80% of people diagnosed with IBS actually have SIBO as the underlying cause — a condition that is testable, treatable, and responds exceptionally well to the right dietary approach.
I am Monash University certified in the low-FODMAP diet, the gold standard for IBS and SIBO treatment. My personal experience navigating SIBO — including being among the first patients to complete a breath test through Dr. Mark Pimentel's research at Cedars-Sinai — gives me a depth of understanding that clinical training alone cannot provide.
For weight management, I address the root causes behind previous failed efforts: hormonal changes, metabolic adaptation, gut dysfunction, and lifestyle patterns. The goal is always permanent results.
