Integrative and functional medicine are similar in that they view and understand the body as one whole organism that cannot be separated into parts. Both are patient-centered, focused on getting to the root cause, are holistic, prioritizing lifestyle, nutrition, and behavioral changes over pharmaceuticals. Functional medicine uses in-depth bloodwork and specialty lab testing to get at the root cause, while integrative practitioners may focus on standard lab testing. Credentialing is different in that Integrative medicine is a board-certified fellowship that MDs and DOs can take and obtain as an official credential. Functional medicine offers both fellowships and post-graduate certifications to MD’s, DO’s. DC’s, NP’s.
