The Eglin Methodology: Finding The Root Cause
Eglin Health operates on the principle that the body is an interconnected system. We do not focus solely on symptoms; we investigate and assess the underlying factors that contribute to imbalance, ensuring lasting, profound results for the client. Our comprehensive methodology is built around two key frameworks:
1) The 4 Key Systems: Our Investigative Framework
Every programme begins with a rigorous functional analysis of these four major regulatory networks. We examine the complex interplay between them to identify the precise area of root cause dysfunction:
-
The Digestive System
The Nutrient Engine & Microbiome Balance.
-
The Immune System
Inflammation Management & Defense Network.
-
The Nervous System
Stress Response & Mind-Body Communication.
-
The Endocrine System
Master Regulator of Metabolism and Mood.
2) The 6 Pillars of Health: The Foundation of Every Programme

-
