In this episode of the Vibrant Wellness Podcast, Dr. Alex Carrasco sits down with functional medicine nutritionist Rachel Scheer, BS, FM, to discuss the root causes behind chronic gut issues, hormone imbalance, and nervous system dysregulation. Rachel shares her personal health journey from competitive bodybuilding and severe digestive illness to becoming a leading voice in functional medicine and SIBO recovery after years of misdiagnosis and unsuccessful conventional treatments.
Throughout the conversation, Rachel explains how chronic stress, cortisol imbalance, poor gut motility, and metabolic dysfunction all contribute to conditions like SIBO and IBS. She breaks down her functional healing framework, including gut testing, personalized nutrition, detoxification support, microbiome repair, and nervous system regulation. The discussion also explores the role of peptides like BPC-157 and Larazotide, the limitations of quick-fix wellness trends, and why healing requires addressing the body as an interconnected system.
The episode emphasizes a central theme of functional medicine: true healing happens when the body feels safe. Rachel and Dr. Carrasco discuss burnout culture, food fear, resilience, stress recovery, and the importance of balancing performance with restoration to create long-term health and metabolic flexibility.
