From The Institute for Functional Medicine website:
Functional Medicine directly addresses the underlying causes of disease by using a systems-oriented approach with transformative clinical concepts, original tools, an advanced process of care, and by engaging both patient and practitioner in a therapeutic partnership.
Functional Medicine is an approach to health care that conceptualizes health and illness as part of a continuum in which all components of the human biological system interact dynamically with the environment, producing patterns and effects that change over time. Functional Medicine helps clinicians identify and ameliorate
dysfunctions in the physiology and biochemistry of the human body as a primary method of improving patient health. Functional Medicine is often described as the clinical application of systems biology.
Chronic disease is almost always preceded by a period of declining function in one or more of the body’s systems. Restoring health requires reversing (or substantially improving) the specific dysfunctions that have contributed to the disease state. Each patient represents a unique, complex, and interwoven set of environmental and lifestyle influences on intrinsic functionality (their genetic vulnerabilities) that have set the stage for the development of disease or the maintenance of health.
