ELIZABETH SOUSA | FUNCTIONALDIAGNOSTIC HEALTH PRACTIONER |CERTIFIED HOLISTIC HEALTH COACH| RN

My Journey
I’m really glad you’re here.
​
My path into functional nutrition grew out of personal and family health challenges that traditional approaches couldn’t fully explain. What began as a search for answers became a deeper study of how the body adapts to stress — and how often symptoms are messages, not failures.
​
Early in my career, I believed that eating “healthy” was the solution. Over time, and through my work as a registered nurse, health coach, and now a Functional Diagnostic Nutrition Practitioner, I came to understand that food is only one part of the picture. Digestion, stress, sleep, hormones, immune health, and the nervous system are deeply interconnected — and when one is under strain, the entire system feels it.
​
This understanding first led me back to school at the Institute of Integrative Nutrition, where I became a certified Health Coach and began expanding beyond a food-only view of health. That training opened the door — but it was through my later work and education as a Functional Diagnostic Nutrition Practitioner that everything truly came together.
​
Through FDN, I learned — or perhaps remembered — that the body is not broken. When we identify and reduce stressors, both obvious and hidden, and support the body’s foundational systems, it knows how to adapt and heal. That framework fundamentally changed how I see symptoms and now guides every client I support.

Today, my work centers on helping clients understand why symptoms are showing up and how to support the body at the foundation. I take a compassionate, physiology-based approach that begins with a thorough health history, foundational support, and — when appropriate — advanced gut testing such as the GI-MAP to uncover hidden stressors. I often begin with digestion, as I see it as one of the most important foundations influencing hormones, immune health, energy, and overall resilience.
​
Much of my practice focuses on women navigating perimenopause and menopause — a season when fatigue, digestive changes, brain fog, weight resistance, and sleep disruption often appear despite doing “all the right things.” In this stage of life especially, pushing harder often backfires. Sustainable change comes from listening and support, not force.
​
At the same time, this approach is not limited to one life stage. The foundations of health apply to everyone. When we support the gut and reduce stress on the system, energy improves, digestion becomes more predictable, hormone symptoms soften, and the body finds its rhythm again.
​
If you’ve been feeling off — more tired, more bloated, or simply not like yourself — consider this a gentle reminder: your body isn’t failing you. It’s communicating.

"Elizabeth, I just wanted to thank you for truly listening to me and helping me understand why my gut health was struggling when no one else could. I feel 100% better. While it took some time to adjust to the lifestyle changes, I’ve fully embraced them and couldn’t be more grateful for your guidance and support."

"Working with Elizabeth has been truly amazing. She is incredibly supportive and knowledgeable. While the number on the scale did go down, what meant even more to me was how much better I felt overall. I had more energy, less brain fog, clearer skin, and a renewed sense of well-being."–Meg
