Our Philosophy

The gut and brain are in constant communication, influencing mood, cognition, and even immune function. At Gut Feeling, we take an integrated, evidence-based approach to health by examining this connection through both biological and psychological lenses.

Our care model unites medical diagnostics, microbiome science, and clinical psychology to provide patients with a complete understanding of how the mind and body interact.

Dr. Linda Thomas

Founder & Principal Clinician Mucosal Immunologist | Clinical Psychologist | Visiting Fellow, ANU

Dr. Linda Thomas is Australia’s only Mucosal Immunologist and Clinical Psychologist, internationally recognized for her pioneering work in psych gastroenterology — the study of how the gut influences brain and emotional health.

As a Visiting Fellow at the Australian National University, Dr. Thomas contributes to ongoing research on immune and neurochemical pathways connecting gastrointestinal and emotional function. She is also a published author and respected media contributor, frequently featured in national conversations about the gut–brain axis and its impact on modern health.

Who We Help

Gut Feeling supports individuals across all life stages — children, teens, adults, mums and bubs, and seniors.
Our approach recognizes that the gut’s influence extends throughout development, shaping mood, hormones, energy, and resilience at every age.

A Personal Journey of Discovery

Dr. Thomas’s commitment to the Gut–Brain field is deeply personal. When her daughter was diagnosed with anxiety and coeliac disease, she witnessed firsthand how the gut and mind profoundly shape one another. This experience deepened her professional mission to bring insight, empathy, and scientific clarity to families navigating similar challenges.
