The Gut-Brain Axis with Dr. Rick Pescatore
In this episode of the Bioactive Podcast, Dr. Riley Kirk sits down with Dr. Rick Pescatore, board-certified emergency physician, Editor-in-Chief of Emergency Medicine News, and founder of BellyMD, for a fascinating deep dive into the gut-brain connection and what it means for cannabis users and patients dealing with unexplained digestive symptoms.
Dr. Pescatore explains how the gut and brain communicate through the vagus nerve, why the gut has been called the “second brain,” and how genetics, diet, gut bacteria, inflammation, and cannabis can all influence this complex system. The conversation also explores cannabinoid hyperemesis syndrome (CHS) and why understanding CHS requires looking beyond cannabis alone and considering the broader gut-brain system.
We also get into GLP-1 medications and gut-brain medicine, nausea and vomiting, microbiome health, micronutrient deficiencies, vitamin B1 (thiamine), magnesium, and whether personalized health data could help us better understand why someone feels unwell. Dr. Pescatore shares how emerging tools, including phenomic data, wearable technology, AI, and the Menome platform, could help patients identify patterns that traditional medicine may overlook.
We also discuss cannabis and the gut microbiome, CHS, thiamine deficiency, antibiotics and gut health, personalized medicine, patient autonomy, and the future of gut-brain healthcare.
In this episode, we explore:
- What is the gut-brain axis and how does the gut communicate with the brain?
- Why does the gut have such a major role in neurotransmitters and brain health?
- What does the gut microbiome have to do with anxiety, depression, and other conditions?
- What is cannabinoid hyperemesis syndrome (CHS), and how does it fit into gut-brain health?
- Could underlying gut-brain dysfunction contribute to cannabis-related symptoms?
- How do GLP-1 medications affect the gut-brain axis?
- What role do vitamin B1, magnesium, and micronutrients play in gut-brain health?
- Can microbiome testing and wearable data help personalize healthcare?
- Could AI help patients better understand their own health?
- What does the future of personalized gut-brain medicine look like?
This is a conversation about cannabis, medicine, the microbiome, nutrition, neuroscience, personalized health, and the emerging science connecting them all.
