Show Notes
Team Gut Girls naturopathic doctors Dr. Dominique Vanier, ND Dr. Whitney Baxter, ND and Dr. Christina Carew, ND discuss chronic digestive symptoms that persist despite normal tests, focusing on disorders of gut-brain interaction (DGBIs), which affect over 40% of adults and children and include IBS, functional dyspepsia, functional constipation/diarrhea, bloating, reflux hypersensitivity, and more under Rome V criteria.
They explain a biopsychosocial model of causes and risk factors (trauma, infection, stress, genetics, early life events, anxiety/depression, sleep, smoking, obesity, surgeries) and myth-bust that bloating isn’t automatically IBS, symptoms aren’t “nothing,” you can have overlapping DGBIs, and the microbiome isn’t the whole answer.
Key mechanisms include motility disturbance, visceral hypersensitivity, altered mucosal/immune function, dysbiosis, and altered CNS processing. Practical options discussed include CBT, gut-directed hypnotherapy, diaphragmatic breathing, consistent movement, personalized food strategies, supplements (nervines, demulcents, motility agents), and medications including neuromodulators, plus advocating for collaborative care and referrals.

Could your bloating, constipation, fatigue, or stubbornly low iron be a clue to celiac disease—even if you’ve never had diarrhea? And if you’ve already gone gluten-free, can you trust a negative celiac blood test? In this episode of Team Gut Girls, Dr. Whitney Baxter, ND and Dr. Dominique Vanier, ND unpack three common celiac disease myths that can delay diagnosis and make gluten-free living more confusing than it needs to be. We explore why what you eat before testing matters, why celiac symptoms can extend well beyond the bathroom, and where gluten cross-contact deserves your attention. Shared toasters and crumb-filled peanut butter jars? Let’s talk. Your shampoo? A different conversation. In this episode, you’ll learn: • Why going gluten-free before testing can lead to a false-negative result • How celiac disease can show up as constipation, bloating, fatigue, iron deficiency, or symptoms outside the gut • What tTG-IgA and total IgA blood tests measure—and where an intestinal biopsy fits in • What to discuss with your healthcare provider if you’re already gluten-free • How family history and other autoimmune conditions can influence screening decisions • Which kitchen habits help reduce gluten cross-contact • Why ongoing symptoms after going gluten-free deserve another look You’ll also leave with practical questions to bring to your next appointment, so you can move from “Could gluten be the problem?” toward a clearer plan.

Bloating, constipation, and that “I went, but I’m still not empty” feeling—could your pelvic floor be part of the puzzle? In this episode of Team Gut Girls, pelvic floor physiotherapist Susannah Stewart joins Dr. Whitney Baxter, Dr. Christina Carew, and Dr. Dominique Vanier to explore an often-overlooked connection in gut health: how your pelvic floor, diaphragm, abdominal muscles, and nervous system work together to help you poop—and what happens when that coordination gets disrupted. If you’re dealing with persistent bloating, straining, trapped gas, or incomplete bowel movements, this conversation offers a fresh perspective on what might deserve a closer look. And yes, you can poop every day and still have constipation. We unpack: How pelvic floor tension and difficulty relaxing can contribute to constipation and abdominal discomfort. Why stress, anxiety, and pain can influence bowel function. Toileting posture and habits that can make emptying easier. Pelvic organ prolapse and its potential role in incomplete evacuation. Dyssynergic defecation—when the muscles involved in pooping aren’t coordinating—and where biofeedback fits. Why “just do Kegels” isn’t helpful advice for every pelvic floor. What to expect from pelvic floor physiotherapy, including consent, comfort, and options beyond an internal exam. Postpartum body image, core recovery, and moving beyond pressure to “bounce back.” Expect practical insights, myth-busting, and an honest conversation about the things we don’t talk about nearly enough. Because understanding your bloating sometimes means looking a little farther south. Learn more and find episode transcripts at https://www.teamgutgirls.com.
