Dr. Vivian Asamoah

Board-Certified Gastroenterologist | Integrative & Functional Medicine Expert | Global Gut Health Leader

I’m Dr. Vivian Asamoah, a triple board-certified physician redefining digestive health through a global, root-cause lens. With over two decades of clinical experience, I specialize in microbiome science, mast cell activation (MCAS), gut-brain axis disorders, and immune-driven GI dysfunction.

Through my practices—Houston Gastro Institute and Dr. Vivian Asamoah Integrative Functional GI—I help patients across the U.S. and internationally heal from IBS, SIBO, SIFO, histamine intolerance, and leaky gut using precision diagnostics, nutrition protocols, and trauma-informed care.

This is whole-person medicine—beyond prescriptions. I don’t just advocate for wellness—I design it, honoring your biology, lived experience, and culture.

When conventional care hits a wall, I offer a new path forward.
