IBD & Gastrointestinal Nutrition

Evidence-based nutrition guidance for Crohn’s disease, ulcerative colitis, IBS, SIBO, gastritis, gastro-esophageal reflux (GERD), bloating, chronic constipation, and other digestive challenges.

Living with IBD or chronic GI symptoms can be exhausting. Flare days, unpredictable digestion, and conflicting nutrition advice can leave you feeling overwhelmed, restricted, or unsure of what to eat.

I provide compassionate, personalized, and evidence-based nutrition support to help you improve your symptoms, support your gut health, and maintain a better quality of life — without unnecessary restriction.

My approach is gentle, practical, and grounded in the latest nutrition science. Together, we work to stabilize symptoms, reduce discomfort, and help you feel more confident and in control of your health.

My Expertise

As a Registered Dietitian Nutritionist with advanced training in GI nutrition and digestive health, I bring both professional expertise and personal understanding to my work. I’ve supported clients navigating conditions such as Crohn’s disease, ulcerative colitis, IBS, SIBO, gastritis, GERD, and chronic digestive symptoms — and with over 20 years of lived experience with ulcerative colitis myself, I know just how nuanced, unpredictable, and overwhelming GI conditions can feel. My approach is empathetic, evidence-based, and grounded in the most current research.

Testimonials

  • “Rachel has a bright, cheery presence that instantly made me feel comfortable. She has so much knowledge about nutrition and how our bodies work, and shares it in a way that’s easy to understand and incorporate into my life. Rachel was a pro at coming up with ideas and alternatives if anything ever didn’t fit quite right into my life, and she always made me feel accepted and supported. She was a big part of my journey to get an IBD diagnosis, and then helped me navigate symptoms and food choices from there. I recommend Rachel to anyone who could use some guidance and support in learning more about nutrition, taking care of their bodies, and meeting their nutrition goals and needs.”

    — RDN Client with Crohn’s disease

  • “After suffering from IBS and SIBO for a very long time, I was longing to finding a more holistic treatment for my conditions. I never knew what to eat or prepare that would ease my painful symptoms. It seemed everything I ate made me sick. I was so grateful when my gastroenterologist recommended that I contact Rachel Dyckman, Registered Dietitian Nutritionist. Rachel has thoroughly enlightened me with nutritional information, educational and shopping tips, meal planning guidance, healthy choices, and helped me to fall in love with food again! She put me on the path of a healthy and nourishing wellness journey that I could have never anticipated or done on my own. Selecting the right things to eat is now such a joy rather than a dreaded chore. For the first time in my life, I feel in nutritional control and so much wiser thanks to Rachel. My symptoms have improved tremendously. Rachel was always quick to respond to my many questions and so easy to talk to about my gastrointestinal symptoms. I am so grateful to have her on my wellness team! Thank you, Rachel, for everything!"

    — RDN Client with IBS & SIBO

  • “My sessions with Rachel were *exactly* what I was looking for. I have Crohn’s disease, so my needs are unique, but I believe that anyone who is interested in understanding nutrition could benefit from her work. She helped me to understand how different foods work together, and gave me very manageable suggestions that were easy to incorporate into my routine.“

    — RDN Client with Crohn’s disease

  • “I started working with Rachel when my GI tract made eating an ordeal. I couldn't find things to eat that didn't hurt my stomach and started unintentionally losing weight. I felt full for much of the day and was frequently bloated. My GI doctor was unable to offer any dietary suggestions while she and I worked to figure out what was wrong. Rachel gave me many concrete suggestions on how to incorporate high quality and nutritious foods that would minimize all of my ongoing GI symptoms. I found this especially helpful since I follow a plant based whole food diet. She gave me optimism that things would get better (and they did!). She was available to answer my many questions and easily helped revise my diet plan over the months we worked together. Most recently we met after I was diagnosed with osteoporosis- and I now feel even more confident knowing how to deal with the challenges of eating (and enjoying) the best foods for bone health. I am so grateful for connecting with Rachel!"
