Manage IBS, SIBO, and Other Digestive Disorders with Guidance from a New York City RDN 


Many patients struggle with IBS (irritable bowel syndrome), SIBO, and digestive issues. They often feel like their life revolves around searching for what is making them feel bad. Constipation, diarrhea, bloating, abdominal pain, weight fluctuations, a chronic upset tummy, and fatigue are just a few of the most common symptoms we see with patients who struggle with gut health. 


It’s not uncommon for patients to begin to fear food — because of how bad they can feel. Another problem we see are patients trying to implement elimination diets on their own, which leaves them vulnerable to malnourishment and nutrient deficiencies. This, too, can lead to disordered eating.


Improving gut health requires both lifestyle and diet changes, ideally with the guidance of a Registered Dietitian Nutritionist.


About 100 trillion bacteria live in our guts.


These trillions of bacteria create their own ecosystem called a microbiome, which has a macro-effect on our health. Executive editor of Harvard Women’s Health Watch, Kelly Bilodeau, writes, “Researchers are beginning to link these tiny creatures to all sorts of health conditions from obesity to neurodegenerative diseases.”


We do know that gut health is directly tied to mental health, weight maintenance, immunology, hormone health, and the prevention of chronic disease


One strategy to improve symptoms of IBS, SIBO and other digestive disorders is to implement a low FODMAP diet. 


FODMAP is an acronym for: Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols. These are short-chain carbohydrates and found in many foods we eat. Foods that contain FODMAP can cause some people to feel bloated, gassy, and even experience abdominal cramping and diarrhea.  


A low FODMAP diet consists in reducing the intake of foods containing FODMAP (not completely eliminating them), then, after a period of 6 – 8 weeks, gradually beginning to re-introduce certain FODMAP containing foods into the diet. 


An RDN from our team will work with you, guide you step-by-step, in an individualized  low FODMAP diet plan to ensure you receive the nutrients and support you need, implement the diet plan properly, and work through the FODMAP protocol. We then work with you to manage the reintroduction phase of some FODMAP containing foods, always monitoring nutrient needs and making modifications when necessary.


Our nutrition experts also consider lifestyle factors that might play into your IBS, SIBO or other digestive issues like anxiety and stress, eating patterns, and food beliefs. 


Work with one of our RDNs to get to the root of your gut issues and related chronic pain. Together, we will develop an individualized nutrition plan to help you feel better, one delicious bite at a time.
