Chronic Diarrhea: A Functional Medicine Approach w/ Dr. Ilana Gurevich Rational Wellness Podcast 483
Episode 483
Wednesday, October 14, 2026 • Duration 55:29
Diarrhea: Root Causes, Testing, and Treatment Strategies with Dr. Ilana Gurevich
Dr. Ben Weitz introduces the Rational Wellness Podcast episode on diarrhea and its complex differential diagnosis, featuring naturopathic gastroenterology specialist Dr. Ilana Gurevich. They discuss defining diarrhea using the Bristol Stool Chart and distinguishing acute from chronic cases, including when to investigate (about 4–5 days for new onset). Gurevich outlines an acute workup using LabCorp's rapid GI Pathogen Profile PCR stool test, notes limitations and false positives, and explains her approach to chronic diarrhea evaluation, including GI-MAP with optional bile acid testing (OMX), pancreatic elastase and steatocrit for fat malabsorption, and assessment for SIBO/SIFO and H. pylori (emphasizing conventional confirmation and virulence factors). They cover bile acid malabsorption and treatment with bile acid sequestrants and fibers, exocrine pancreatic insufficiency and enzyme dosing, microscopic colitis requiring diagnostic colonoscopy biopsies and budesonide, carbohydrate malabsorption breath testing, hydrogen sulfide SIBO uncertainty, the role of stress/nervous system and motility, and supplement causes like excess magnesium or vitamin C.

The HRT Questions Most Women Never Get Answered with Karen Martel | Rational Wellness Podcast 481
Perimenopause to Menopause: Testing, Progesterone First, and Evidence-Informed HRT with Karen Martell Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews hormone specialist Karen Martell about perimenopause and menopause, emphasizing that midlife hormonal shifts affect metabolism, sleep, mood, cognition, bone and cardiovascular health. Martell says perimenopause can begin in the mid-30s, often with declining progesterone from less frequent ovulation, leading to heavy periods, insomnia, anxiety, and perceived "estrogen dominance," while estrogen later becomes erratic and then declines toward menopause around age 51. She critiques common responses like birth control, hysterectomy, and symptom-only medications, and recommends combining bloodwork with saliva or urine metabolite testing (e.g., DUTCH) when cycling. For HRT, she prefers transdermal estradiol over oral estrogen, discusses progesterone delivery options and sensitivities to oral metabolites, addresses testosterone (often compounded; injectable preferred), and notes roles for DHEA and pregnenolone. She also covers vaginal therapies, dosing based on both symptoms and protective lab ranges, and cautious later-life initiation. 00:00 Show Intro and Mission 00:59 Why Midlife Hormones Matter 02:23 Perimenopause Starts Early 03:18 Progesterone Drop Signs 06:17 Testing Hormones and Thyroid 08:02 Bad Advice and Quick Fixes 09:33 When Supplements Aren't Enough 10:52 Starting Progesterone Therapy 12:49 Best Hormone Testing Methods 15:36 Endocrine Disruptors Cleanup 17:40 Choosing Estrogen Delivery 18:43 Pellets and Testosterone Risks 22:27 Progesterone Forms and Dosing 25:21 Why Avoid Oral Estrogen 27:00 Estradiol for Life 27:38 Estriol vs Estradiol 30:23 Patch vs Cream Dosing 31:56 E4 Estrogen Debate 33:39 Cycling Progesterone 35:38 DHEA and Pregnenolone 37:39 Vaginal Hormone Options 40:18 Optimizing HRT Levels 43:52 Starting HRT After 70 47:45 Perimenopause Timing Tips 50:19 Where to Find Karen

What are the Functions of Microbial Gases, Hydrogen, Methane, & Hydrogen Sulfide with Dr. Tom Fabian | Rational Wellness Podcast 480
Gut Microbial Gases Beyond SIBO: Hydrogen, Methane, and Hydrogen Sulfide as Signaling Metabolites Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Tom Fabian, PhD, to discuss gut microbial gases beyond the usual SIBO framing. They explain that hydrogen, methane, and hydrogen sulfide are normal microbial metabolites with potential signaling roles, alongside key microbiome products like short-chain fatty acids (especially butyrate), which fuels colon cells, supports tight junctions, regulatory T cells, and helps maintain an anaerobic colon environment. Fabian notes metabolomics (e.g., GI-MAP stool add-ons) can provide functional insight beyond which microbes are present, highlighting butyrate producers such as Faecalibacterium and Roseburia. They review controversies in breath testing interpretation, discuss methane biology and debated links to constipation, and emphasize emerging research that hydrogen sulfide is widely produced (often from cysteine metabolism), supports colon mitochondria and anaerobiosis, may relate to stress responses and longevity, and that excessive sulfur restriction may be misguided; fiber and polyphenols may mitigate protein-driven hydrogen sulfide. 00:00 Show Intro 00:59 Why Gut Gases Matter 04:04 Microbiome Metabolites 05:52 Butyrate Deep Dive 09:07 Measuring SCFAs 13:20 Hydrogen and Breath Tests 19:12 Hydrogen Benefits 28:19 Methane and Motility 31:06 Sponsor Break 32:13 Methanogens Explained 35:24 Hydrogen Sulfide Science 50:59 Clinical Takeaways

Environmental Toxins and Health with Dr. Joe Pizzorno | Rational Wellness Podcast 477
Episode 477
Tuesday, September 1, 2026 • Duration 57:46
Environmental Toxins, Wildfire Smoke, and Practical Detox Strategies with Dr. Joe Pizzorno Dr. Ben Weitz hosts the Rational Wellness Podcast and interviews Dr. Joe Pizzorno on latest research about environmental toxins, emphasizing wildfire smoke risks, PM2.5 penetration, rapid body and brain distribution, and links to neurological, respiratory, and cardiovascular disease. Pizzorno argues toxins are a primary, solvable driver of chronic illness and that oxidized cholesterol reflects toxic exposure more than cholesterol itself. Practical protections include running high-MERV (≥12, ideally 16) HVAC filtration 24/7, avoiding incense, and supporting detox with glutathione (liposomal or via NAC), increased and diverse fiber to reduce toxin reabsorption, and saunas to sweat profusely (except PFAS "forever chemicals," which don't excrete via sweat). They discuss mercury release from forest fires, microplastics and gut binding, arsenic reduction from rice cooking, water filtration (carbon block, RO for arsenic), endocrine disruptors like bisphenols, and toxin assessment using GGTP, ALT, eGFR, and urinary 8-OHdG rather than challenge tests. 01:02 Meet Dr Joe Pizzorno 02:24 Wildfires and Toxic Exposure 05:21 PM2.5 and Systemic Damage 07:24 Cholesterol Oxidation and Toxins 09:35 Home Air Filtration Tips 11:25 Mercury From Forest Fires 13:15 Glutathione and NAC Basics 14:41 Binders and Fiber Strategy 17:26 Persistent vs Nonpersistent Toxins 19:21 Saunas and Forever Chemicals 21:47 Microplastics and Gut Binding 24:13 Post Fire Cleanup Safety 25:21 Arsenic in Water Rice Chicken 27:54 Whole House Water Filters 29:08 Chlorine Fluoride Tradeoffs 31:08 Plastic Bottles and Bisphenols 31:54 Endocrine Disruptors Explained 33:58 Phytoestrogens vs Xenoestrogens 35:49 Safer Drinkware and Cookware 36:37 Testing Toxins Smarter 39:49 Biomarkers GGTP ALT eGFR 44:37 Detox Nutrition and Glutathione 46:54 Toxins and Autoimmune Disease 48:22 Cure Versus Suppression 53:44 Final Thoughts and Outro

The Microglia are a Key to Brain Health with Dr. David Perlmutter | Rational Wellness Podcast 475
Dr. David Perlmutter on Microglia, Metabolism, and a New Paradigm for Neurodegenerative Disease
Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews neurologist and author Dr. David Perlmutter about his upcoming book, Brain Defenders, describing a neuroscience shift from neuron-centered thinking to the brain's immune cells (glia/microglia) as key drivers of neurodegeneration. Perlmutter argues microglial polarization (supportive M2 vs destructive M1) is upstream of protein accumulations like beta-amyloid, alpha-synuclein, and phosphorylated tau, and is strongly influenced by lifestyle-driven metabolic health (blood sugar, insulin resistance, lipids, blood pressure), systemic inflammation, gut dysbiosis, and blood–brain barrier integrity. They discuss prevention, multimodal treatment approaches (e.g., Bredesen and Ornish/Tanzi), mitochondrial dysfunction, exercise, supplements (olive oil polyphenols, vitamin D, CoQ10, urolithin A, spermidine, dihydromyricetin, rosmarinic acid), and emerging drug strategies including TREM2 targeting and GLP-1 agonists, noting benefits and risks.

Rational Wellness Podcast Episode 020: Bioidentical Hormones for Women with Dr. Jill Stocker
Episode 20
Monday, August 17, 2026 • Duration 32:41
Rational Wellness Podcast Episode 020: Female Hormones with Dr. Jill Stocker Dr. Jill Stocker discusses the use of bioidentical estrogen and progesterone hormones to help women restore their youth and vigor and their "juiciness". I laid out the topic first by talking about how it was believed for decades that estrogen was protective for the heart, which is why women have a lower risk of heart attack than men until menopause and then their risk increases equal to men's. There was however, concern about the increased risk of breast and ovarian cancer. When the Women's Health Initiative study was published in 2002 it shook the field of women's hormone replacement therapy by demonstrating an increased risk of heart attack and stroke in women who took equine (from horses) estrogen and synthetic progestins (Premarin and PremPro). But these results do not necessarily apply to the use of bioidentical hormones, which are much safer.
