Do you feel confused and overwhelmed by what to eat? Have you been feeling "off" for so long you can't remember what normal feels like? Are you struggling with gas, bloating, diarrhea, heartburn, and/or constipation? I provide supportive nutrition counseling for gut problems. I help adults and children who struggle with digestive issues, such as Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), Small Intestinal Overgrowth (SIBO), Candida overgrowth, Gastroesophageal Reflux Disease (GERD), Celiac Disease, and food allergies. We will get to the root of the problem so you can eat with freedom and comfort.
