630. How to FIX Your Gut to Fix Your Hormones
The Thyroid (and Hormone) Fixer Podcast: Thyropause, Menopause, Metabolism and How to Fix ItShow Notes
In this episode, I sit down with board certified endocrinologist Dr. Cassie Smith to unpack the powerful connection between your gut, hormones, metabolism, and overall health. We dive into why so many people are still struggling despite “normal labs,” why conventional medicine continues to miss key thyroid markers, and how gut dysfunction can quietly sabotage everything from T3 conversion to estrogen metabolism. Dr. Cassie shares her own story of being medically gaslit, dismissed, and forced to search for answers after Graves’ disease turned her life upside down, and how that journey completely transformed the way she practices medicine today. We talk about reverse T3, leaky gut, autoimmune disease, estrogen dominance, cancer risk, thyroid medication misconceptions, and the frustrating “eat less, exercise more” advice that continues to fail women every day. Dr. Cassie also shares practical free strategies anyone can start implementing immediately to support healing and finally feel better. What you’ll learn: Why “normal labs” might still leave you feeling completely hypothyroid The surprising role gut bacteria play in thyroid hormone conversion What actually happens when T3 cannot get into the cell The hidden connection between estrogen metabolism and gut health How stress and inflammation can quietly sabotage every hormone in your body Why some hormone clinics may actually be making symptoms worse Be sure to subscribe, leave a review, and tag us on social media with your biggest takeaway from the episode.

What if the reason you keep ending up in the kitchen at night, eating when you're not even hungry, has nothing to do with willpower? In this episode, I'm joined by Amber Romaniuk, who works with women on emotional eating, binge eating, digestion, and hormones, to unpack why food becomes the way so many of us cope with stress, quiet our thoughts, and take care of everyone but ourselves. Amber shares her own journey through binge eating, food addiction, and bulimia, and I open up about the disordered eating I went through during my bodybuilding years. We also get into the differences between emotional eating, binge eating, bulimia, and food addiction, how cortisol, poor sleep, low progesterone, and thyroid issues can turn up the volume on cravings, and why the shame spiral after a binge can keep the whole cycle going. Amber shares what to do after a binge instead of restricting or over-exercising, what real progress looks like beyond the scale, and her honest take on fasting and GLP-1s when you're healing your relationship with food. What you'll learn: Why emotional eating is rarely about willpower, and what may be driving it instead How repeating the same eating patterns can wire a habit pathway in your brain What separates emotional eating, binge eating, bulimia, and food addiction How high cortisol, poor sleep, and low progesterone can amplify cravings Why skipping meals with low thyroid function can set you up for nighttime overeating What to do after a binge instead of restricting, fasting, or over-exercising What progress looks like beyond the number on the scale Why Amber believes fasting and GLP-1s aren't the answer for healing your relationship with food Tune in to learn how to break the emotional eating cycle and build a relationship with food that isn't driven by shame.

What if the reason you still feel exhausted, foggy, and stuck isn't your thyroid or your hormones on their own, but the fact that no one is treating them together? In this episode, I'm breaking down why your thyroid and your sex hormones (estrogen, progesterone, and testosterone) play in the same sandbox, and why splitting them between two providers who never talk to each other can leave you coordinating your own care. Consider this my public service announcement on hormones-in-a-box clinics, algorithm-based dosing, and what improperly managed hormones can mean for your health and longevity. We also get into why you can't supplement your way to optimal sex hormone levels, why "within normal limits" isn't the same as optimal, and how oral estrogen can raise binding proteins like SHBG (sex hormone binding globulin) and TBG (thyroid binding globulin), which may leave you feeling worse. I also share the exact questions to ask before you start hormone therapy, the red flags to watch for, and the training I look for in a hormone provider. What you'll learn: Why your thyroid and sex hormones need to be treated together, not by two separate providers Why supplements and over-the-counter creams can only take you so far in perimenopause and menopause What "within normal limits" misses, and why a total testosterone of 40 may still be below optimal for women How oral estrogen can raise SHBG and TBG and affect your thyroid and testosterone Why estrone matters and why it's worth testing alongside estradiol Which questions to ask a provider before you hand over your money What red flags to watch for in hormones-in-a-box and pop-up hormone clinics Why you may still benefit from progesterone even if you don't have a uterus Tune in to learn how to find a provider who knows which lever to pull when your body doesn't follow the textbook.

What if one of the most useful health trackers you could own wasn't on your wrist, but on your toilet? In this episode, I'm joined by Scott Hickle, engineer and founder of Throne, a camera that clips onto your toilet and tracks your gut health, hydration, and bathroom habits every time you go. We get into what your poop and pee can reveal about your health and what the Bristol Stool Scale (a 1-to-7 chart of stool form) actually tells you. We also cover why your memory of your own bathroom habits is far worse than you think. We also talk about how Throne's AI helps you connect gut changes to stress, travel, food, supplements, or new medications like GLP-1s. Scott walks through what can throw off the readings, from blue toilet cleaner to vitamin B and methylene blue. He explains why embarrassment can keep people from getting checked for things like colon cancer. He also shares a surprising link between under-hydration, vasopressin (the hormone that helps your body hold onto water), and your blood sugar response, which I connect back to thyroid function and weight. What you'll learn: What your stool form, color, and frequency can reveal about your gut health How Throne tracks hydration, bathroom habits, and urinary flow automatically Why your memory of your own bathroom habits is so unreliable How to run your own experiments with diet, supplements, probiotics, and GLP-1s What can throw off hydration readings, from vitamin B to methylene blue Why Scott believes embarrassment is a real risk factor for delayed diagnosis - How under-hydration may affect your blood sugar, thyroid, and weight What Scott says to look for in the toilet tomorrow, with or without a device If you've ever ignored what's happening in the toilet, this episode will show you why it's worth paying attention. Tune in to learn what your poop and pee may be telling you about your health, and why it's worth paying attention to what's happening in the toilet. ——— Thyroid Fixer listeners can save on Throne at https://thronescience.com/discount/DRAMIE or use code DRAMIE at checkout.

What if Alzheimer's doesn't begin when you start forgetting things, but decades earlier, with your blood sugar, your waistline, and your hormones? In this episode, I'm joined by Dr. David Perlmutter, Board-Certified Neurologist and author of Grain Brain and his new book, Brain Defenders, to unpack why your brain's future is something you can influence. We talk about microglia, the brain's own immune cells, how they shift from protecting your brain to damaging it, and why chasing beta amyloid may be missing the bigger picture. We also get into how thyroid hormone, especially T3, fuels the mitochondria that help keep those immune cells supportive. We look at why the drop in estrogen during perimenopause may help explain why two-thirds of Alzheimer's patients are women. Dr. Perlmutter shares where he stands on hormone replacement therapy and testosterone and what the research says so far about GLP-1 medications and brain health. He also names the labs he wants everyone in their 30s, 40s, and 50s to know, including fasting insulin, A1C, and homocysteine. What you'll learn: Why Alzheimer's may begin decades before memory loss shows up Why Dr. Perlmutter says carrying the APOE4 gene variant means predisposed, not predetermined What microglia are and how they shift from supportive to destructive How blood sugar, gut inflammation, and head trauma can all affect your brain's immune cells How thyroid hormone and your mitochondria work together to support brain energy Why falling estrogen during perimenopause may put women's brains at greater risk Where Dr. Perlmutter stands on hormone replacement therapy and testosterone What the research says so far about GLP-1 medications and the brain Tune in to learn how to start protecting your brain now, long before any symptoms show up.

Gut health is about far more than bloating and constipation. In this episode, I’m joined by Laura Frontiero to unpack the overlooked ways gut dysfunction can show up, from fatigue and brain fog to skin issues, joint pain, sleep problems, and thyroid challenges. We also talk about why common gut protocols don’t always work and why the order in which you address gut health matters.
