Are your stomach issues controlling your life? Perhaps you have been diagnosed with IBS (Irritable Bowel Syndrome) or SIBO, or given no diagnosis at all. Have you tried probiotics and other natural remedies, but nothing has worked? And after countless doctor visits and google searches, you’re frustrated and discouraged? I get it. I’ve been there, as have so many of my clients. I’m Alyssa Simpson, a Registered Dietitian and Certified Gastrointestinal Nutritionist specializing in digestive issues. I’m dedicated to resolving the root cause of your troubling symptoms — not just giving you a temporary fix.
First, we use evidence-based strategies and sometimes advanced functional testing to uncover foods and other stressors you may have had no idea were impacting your digestive problems. Then, since we will know exactly what is out of balance in your system, we turn our attention toward supporting, healing, and restoring those specific areas.
I know how discouraging it is for people with digestive issues to find answers. I've been in your shoes with my own struggles. The medical system often offers bandaids but no lasting solutions. I'm here to tell you, we see amazing results with digestive issues when we use diet and lifestyle interventions. Don't suffer for one more day when there is help!
