  Sexual Health, Pleasure, and Oxytocin: Clinical Priorities for Vitality | E45

  Aug 10, 20261h 1m

  Most hormone conversations center on estradiol, progesterone, insulin, and cortisol. This one makes room for a hormone many practitioners may be overlooking. On Functional Medicine for Real World Impact, host Tracy Harrison sits down with Dr. Anna Cabeca, triple-board-certified physician, OB-GYN, and bestselling author of The Hormone Fix, to talk about why oxytocin belongs in the clinical conversation around perimenopause, menopause, sexual health, and vitality. Dr. Cabeca calls oxytocin the queen mother of hormones. When it is high, patients are more connected, more responsive, and more likely to shift into an anabolic state. When chronic stress keeps cortisol elevated, oxytocin can become suppressed, and that is when patients may start saying they love their partner but feel nothing, or that they care about their work but cannot access that feeling anymore. That presentation is not just a mindset problem. It is physiology, and it is worth addressing. The conversation covers what it looks like to make sexual health a clinical priority without making patients uncomfortable, why pelvic exams and vaginal health screenings are non-negotiable as women age, and how common medications like antihistamines and antidepressants can quietly disrupt desire and orgasm in ways practitioners often overlook. Dr. Cabeca also shares the language she uses to open these conversations naturally, practical oxytocin-supporting tools across lifestyle and nutrition, and when to consider prescription support for patients who have been in a state of disconnect for so long they no longer remember what vitality feels like. For practitioners working with women in perimenopause, menopause, and beyond, this conversation offers a more complete way to think about hormones, intimacy, pleasure, and clinical care.

  Trauma Physiology: Clinical Wisdom to Deepen (vs. Derail) Practitioners' Clinical Impact | E44

  Jul 27, 202656 min

  You built the perfect protocol and your patient still does not improve. The missing piece might be trauma biology in functional medicine practice, not another test or supplement. Dr. Aimie Apigian joins host Tracy Harrison on Functional Medicine for Real-World Impact to unpack why unresolved trauma quietly derails even the best-designed treatment plans. Dr. Apigian breaks down stress response vs. trauma response in a way that reframes how you read a patient the moment they sit down. One posture signals a person ready for a plan. Another signals someone who needs safety first. She shares a single question she asks to gauge where a patient's nervous system is before anything else. Then there is the auditorium analogy. Dr. Apigian walks through how the same room feels different depending on which survival state a person carries into it, and why that decides whether your protocol lands or gets ignored. The conversation moves into trauma-informed functional medicine and the somatic techniques Dr. Apigian reaches for before handing a patient the full protocol. They also land on a point from her book. Unresolved trauma might be the most overlooked root cause in chronic illness, and most practitioners miss the signs. Listen now to hear how the smallest step, not the biggest protocol, opens the door to real change.

  Nitric Oxide Nuances that Practitioners Need to Know | E43

  Jul 13, 202630 min

  Why do so many patients with textbook risk factors still struggle with high blood pressure, fatigue, and poor circulation even after the obvious fixes? On this episode of Functional Medicine for Real-World Impact, host Tracy Harrison makes the case that nitric oxide challenges are often misunderstood when practitioners focus only on production. Tracy reframes nitric oxide and hypertension as a story about loss, not just lack. She explains why some patients may be making nitric oxide, but losing too much of it through oxidative stress, inflammation, poor oxygenation, metabolic dysfunction, toxicity, or other upstream drivers. This distinction changes how practitioners can think about endothelial dysfunction treatment, especially in patients who are not responding to standard nitric oxide support. She also addresses factors that are easy to overlook in clinical practice. eNOS uncoupling can turn the enzyme meant to support nitric oxide production into one that contributes to oxidative stress. Tetrahydrobiopterin (BH4) deficiency can block nitric oxide synthesis in a separate, often overlooked way. Tracy also unpacks the oral microbiome’s role in nitric oxide production and explains how something as routine as mouthwash may interfere with a patient’s progress. This conversation gives practitioners a more complete map of nitric oxide deficiency causes and a reason to look upstream before reaching for another supplement. Episode Breakdown: 00:00 Nitric Oxide Nuances Practitioners Need to Know 01:35 Five Early Signs of Impaired Nitric Oxide Signaling 06:59 Two Pathways the Body Uses to Make Nitric Oxide 09:24 Why Nitric Oxide Loss Matters More Than Production 14:12 How eNOS Uncoupling Triggers Oxidative Stress 17:18 Tetrahydrobiopterin (BH4) and Nitric Oxide Synthesis 19:24 Oral Microbiome and Nitric Oxide Production 23:49 Nitric Oxide's Role in Mitochondria and Brain Health 26:11 Building a Clinical Framework for Nitric Oxide Support SAFM Links: Take SAFM’s 10 CME course - The Essential Gut Deep Dive Get weekly Clinical Tips in your inbox Learn more about SAFM’s practitioner training Subscribe to our YouTube channel Access quick clinical tips on Facebook Podcast production and show notes provided by HiveCast.fm

  How Hormone Havoc Surprisingly Begins in the Gut | E42

  Jun 15, 202643 min

  Most hormone protocols fail because they start in the wrong place. Practitioners spend years chasing estrogen dominance, sluggish thyroid, and cortisol dysregulation without ever looking at what's driving those patterns. Tracy Harrison makes the case in this episode that the hormone imbalance root causes you're missing are often sitting upstream in the digestive tract. Gut health and hormone imbalance are far more connected than most clinical training suggests. Hormone synthesis, conversion, metabolism, and clearance all depend on a functioning digestive system. When that system breaks down, hormones follow. Tracy walks through five key insights every functional medicine practitioner needs to know. She explains how maldigestion, nutrient absorption, and hormone synthesis are all tied together, and how patients on acid-suppressing medications, those with type 2 diabetes, and anyone with fatty liver disease are quietly losing the raw materials hormone synthesis depends on. She also covers how gut hormones like GLP-1 and GIP directly regulate insulin in ways that go far beyond standard assessment. How T4-to-T3 conversion and gut dysfunction silently undermine thyroid function even when the thyroid gland itself looks fine. The episode also looks at how gut microbiome estrogen metabolism gets disrupted when bacterial overgrowths like commensal E. coli and SIBO-associated bacteria produce beta-glucuronidase, an enzyme that pushes estrogen metabolites back into circulation instead of out of the body. And how cortisol and gut dysfunction drive each other, with dysbiosis and intestinal permeability actively generating HPA axis activation, not just responding to it. If you have patients who are doing everything right and still not getting better, this episode gives you a new place to look. Episode Breakdown: 00:00 Gut Health and Hormone Imbalance: Why the Gut Is Where It Often Starts 02:24 Maldigestion, Malabsorption, and the Nutrients Hormones Depend On 04:51 Acid-Suppressing Medications and Their Hidden Impact on Digestion 07:16 Type 2 Diabetes, Exocrine Pancreatic Insufficiency, and Digestive Enzyme Deficiency 11:57 How Gut Dysmotility and the Microbiome Affect Insulin and GLP-1 Function 16:35 Short-Chain Fatty Acids, Fiber, and Metabolic Hormone Regulation 19:02 T4 to T3 Thyroid Hormone Conversion in the Gut 23:45 Estrogen Metabolism, Methylation, and the Role of Gut Microbiome 28:18 Beta-Glucuronidase, Dysbiosis, and Estrogen Dominance 30:30 Cortisol, Gut Dysfunction, and the Stress Hormone Feedback Loop SAFM Links: Take SAFM’s 10 CME course - The Essential Gut Deep Dive Get weekly Clinical Tips in your inbox Learn more about SAFM’s practitioner training Subscribe to our YouTube channel Access quick clinical tips on Facebook Podcast production and show notes provided by HiveCast.fm

  A Seasoned NP Discovers Passion and Courage to Live Her Purpose | E41

  Jun 1, 202644 min

  Some practitioners find functional medicine through curiosity. Heather Slusher found it through a tendon rupture. On this episode of Functional Medicine for Real-World Impact, host Tracy Harrison sits down with Heather to explore what functional medicine for nurse practitioners really means when it's built from personal crisis, clinical curiosity, and a deep desire to practice differently. Heather's path into root-cause medicine started with a single antibiotic prescription. After taking fluoroquinolone for a sinus infection, she suffered a tendon rupture in her foot and spent years navigating fluoroquinolone toxicity symptoms at a time when many providers still did not recognize them. She never went back to practicing the same way again. What she built from it isn't a rejection of conventional medicine. Chronic disease is where the conventional model falls short, not because of the people in it, but because the system isn't designed to ask why. Functional medicine clinical practice fills that gap by treating the whole person instead of matching symptoms to a protocol. Nine years after launching her integrative medicine practice in Florida, Heather is opening a second location. She starts every patient relationship by asking what they most want to fix, then works from there. Overtesting without a clear action plan leaves patients overwhelmed and no closer to feeling well, and Heather has seen too many people give up because of it. The patient stories speak for themselves. A long COVID patient reported 90 percent improvement in a month with a targeted long COVID treatment plan. A woman who was wheeled in after one dose of Levaquin was driving again within two months. A school principal with two decades of undiagnosed Hashimoto's finally felt like herself. Functional medicine for nurse practitioners isn't just a career pivot. For Heather, it's the whole point.
