Functional Medicine: Pseudoscientific Silliness

BY HARRIET HALL, M.D.

Language keeps changing.

The oft-quoted quip is appropriate here: Do you know what you call alternative medicine with evidence? Medicine.

How is Functional Medicine Different from Conventional Medicine?

Functional medicine was invented by a single individual: Jeffrey Bland. He’s not a medical doctor. He’s a Ph.D. who sells dietary supplements. His supplement companies have been fined repeatedly by the FTC and FDA and have been ordered to stop making medical claims for their products. A number of health care providers have “jumped on the Bland wagon” and claim to be practicing functional medicine.

It’s hard to pin down a definition of FM; each FM provider describes it differently. Dr. Mark Hyman says conventional medicine is dysfunctional, and FM is the opposite. He thinks conventional medicine is as obsolete as phrenology and bloodletting; he also rejects the germ theory of disease. He says diseases don’t exist; they are merely “the downstream symptoms of a mechanism.” The official organization, the Institute for Functional Medicine, says this:
