Sarah's Journey
From Patient to Partner
My Commitment: Expertise Born from Experience
I’m Sarah Eglin, founder of Eglin Health and a Registered Nutritional Therapy and Lifestyle Medicine Practitioner (mBANT). My path to this work wasn’t just a career choice; it was born from a decade of navigating my own way through chronic illness and back to vitality. I combine clinical science with the perspective of someone who has truly been there—offering you a partnership that values both deep expertise and genuine, lived empathy.
From Crisis to Clarity: Finding My Limits
For 20 years, I lived a life of extremes. I balanced a demanding corporate career with the intense training of an Ironman triathlete. I pushed myself constantly, completely unaware that I was draining my body’s natural reserves without giving anything back.
Looking back, I was "running on empty." Lacking the tools to manage stress, I literally ran, cycled, and swam myself into the ground. My health crisis became my greatest teacher, showing me that even the strongest spirit needs a body that is supported from the inside out.
The Turning Point: Chronic Illness and a Diagnosis
My world shifted in 2014 with the onset of Chronic Fatigue Syndrome. It felt as though the lights had been turned off overnight. Then, in 2016, while 41 weeks pregnant, I received a devastating breast cancer diagnosis.
I initially followed the conventional clinical path, but the side effects were severe and compounding: relentless fatigue, immune dysfunction, and nerve damage to name a few. As I navigated these challenges—while trying my best to also care for my new baby—I increasingly felt that the path I was on failed to provide benefits that outweighed the associated risks. It was an incredibly demanding period, yet it became the catalyst for a profound transformation.
Frustrated by an approach that offered few answers for root causes and lacked proactive steps for recurrence prevention, I realised that mere survival was inadequate. It wasn’t good enough for me, and it certainly wasn’t good enough for my son. I committed myself to true holistic health—determined to fully regain my vitality and optimism, free from the anxiety and fear of relapse. This is my story of transformation: a journey that required profound change, unwavering commitment, and a deep dive into the 6 Pillars of Health that now form the foundation of Eglin Health.
Rebuilding My Foundation: The 6 Pillars in Practice
My recovery wasn't about one "miracle cure"; it was about making small, meaningful changes across the six areas of life that matter most. I became my own case study, testing and refining what truly worked:
-
Theraputic Nutrition
I moved to a wholefood, plant-based approach, focusing on the nutrients my body needed to repair itself.
-
Exercise & Movement
I learned to listen to my body, ensuring exercise was a source of energy rather than another stressor.
-
Restoration & Repair
I finally prioritised sleep and rest, giving my body the window it needed to heal.
-
Mental & Emotional Wellbeing
Through psychotherapy and meditation, I addressed the "hidden" stressors of suppressed emotions and harmful taught beliefs.
-
Connection & Support
I cultivated a circle of supportive relationships that fueled my emotional strength.
-
Environmental Optimisation
I reduced the "toxic load" on my system, from the food I ate to the products I used in my home.
Life Beyond: Living Proof of What’s Possible
Through this journey, I didn't just get my health back; I found a better version of it.
In 2025, I stood on the start line of the Barcelona Ironman and finished in 12 hours and 6 minutes—my second-best time ever. It was a deeply emotional milestone. It proved to me that when we give the body what it truly needs, it has an incredible capacity to overcome and thrive.
I’ve walked this road, I’ve felt the frustration, and I’ve experienced the breakthrough. Now, I want to use everything I’ve learned to help you do the same.
“We fall, we break, we fail... But then we rise, we heal, we overcome.”
From Struggle to Success: A Life Built on Holistic Principles
The Illusion of Invincibility
Life before 2014: I was defined by professional discipline and the grit of long-distance athletics. I felt utterly invincible, unaware that I was rapidly draining the very reserves I needed most. Looking back at these photos, I can see what I couldn't then: a system pushed to its absolute breaking point.

Crisis, Motherhood, and the Turning Point
2015 to 2019: This was my darkest chapter. Navigating chronic fatigue and a cancer diagnosis while learning to be a mother was an overwhelming challenge. This period wasn't just about survival; it was the crucible that forced me to stop, reflect, and find a fundamentally new way to live.
