Relational Existence-Based Medical Theory: The Multi-Layer Network Homeostasis Model

Modern medicine has traditionally adopted an organ-specific and reductionist approach to disease. However, the increasing prevalence of chronic, mental, and multi-morbid conditions reveals the insufficiency of this framework. This study introduces the philosophical framework of Relational Existence Theory into medicine, modeling the individual as a multi-layer relational network and redefining health as a variable stability region maintained by dynamic interactions.
