The Gut-Thyroid Link Your Doctor Isn't Testing For with Dr. Izabella Wentz

What if your "normal" thyroid labs aren't telling the full story? In this eye-opening episode of The Girlfriend Doctor Show, Dr. Anna Cabeca sits down with renowned integrative pharmacist and thyroid expert Dr. Izabella Wentz to uncover the powerful connection between gut health, IBS, autoimmune disease, and thyroid dysfunction — especially Hashimoto's. Dr. Wentz shares her deeply personal journey from debilitating IBS, anxiety, fatigue, and Hashimoto's thyroiditis to healing through root-cause medicine. Together, Dr. Anna and Dr. Wentz explore why so many women are told their thyroid labs are "normal" while they continue struggling with weight gain, brain fog, bloating, constipation, inflammation, hormonal shifts, and exhaustion. You'll learn why gut permeability ("leaky gut"), chronic stress, infections, food sensitivities, and microbiome imbalances may be silently driving autoimmune thyroid disease — and the practical steps you can take to begin healing. In this episode, you'll discover: Why thyroid antibodies matter — even when TSH appears "normal" The hidden connection between IBS and Hashimoto's How stress hormones disrupt the gut barrier and immune system Common root causes including parasites, H. pylori, SIBO, mold, and food sensitivities The truth about bloating, constipation, diarrhea, edema, and inflammation Functional medicine testing that may uncover what conventional medicine misses Nutrition, supplements, and gut-healing strategies that can support thyroid recovery If you've ever been told "everything looks fine" while your body says otherwise, this conversation is for you.
