Bringing Hope, driven by science. Isabelle Amigues, MD, is a physician scientist with a speciality in rheumatology. She has trained both in Paris, France as well as Columbia University, in New York City. At age 40, in the midst of an existential crisis, she was diagnosed with stage IV metastatic breast cancer. A timely meeting with a non-traditionally trained practitioner taught her a different approach to disease. She experienced the power of meditation, visualization, energy healing and love. Her journey through cancer inspired her to learn more about these alternative approaches, and now that she has studied many of them she has integrated them into her own practice of medicine. Dr. Amigues is the author of multiple book chapters and scientific articles in rheumatology. She is the founder and CEO of UnabridgedMD.

Gut Health, Antibiotics & Post-Infectious Syndromes: Dr. Katrina Coulter on the Microbiome, Post-Lyme, and Long COVID
Did you know the trillions of microbes in your gut might shape everything from your immune system to your mental health—and even how you recover after an infection? 🌱
In this episode of the UnabridgedMD Podcast, Dr. Isabelle Amigues welcomes Dr. Katrina Coulter, infectious disease specialist, to explore the fascinating world of the microbiome. Together, they dive into the overlap between infectious disease and rheumatology, the hidden consequences of antibiotic use, and the complex challenges of post-Lyme disease, chronic fatigue, and long COVID.
This conversation blends cutting-edge science, clinical wisdom, and practical advice—from why fiber is the #1 nutrient most of us are missing, to how farming practices affect our gut health, to why listening to patients is still the most powerful diagnostic tool.
If you’ve ever wondered whether your gut health could hold the key to remission and resilience, this episode is for you.
