Functional pathology is the study and evaluation of how the human body functions and how dysfunction may manifest. There are several synonyms for functional pathology that are often used interchangeably, such as dynamic pathology, integrative pathology, and physiological pathology. These terms highlight the emphasis on the whole body and its interwoven systems, rather than just treating individual symptoms or diseases in isolation. Additionally, functional pathology is closely related to other fields such as functional medicine, which also emphasizes a holistic approach to understanding and treating illness. Regardless of the term used, the goal of functional pathology remains the same: to identify and address the root causes of dysfunction and restore optimal function to the body.
