Functional medicine takes a root-cause, systems-based approach — often useful for chronic fatigue, gut issues, autoimmune conditions, and hormonal symptoms that got a shrug at a standard visit.

What to look for

IFM-certified practitioner (IFMCP) or comparable formal training.
Uses conventional labs first, specialty testing (GI-MAP, DUTCH, organic acids) only when it will change the plan.
Coordinates with your primary care and specialists, not replaces them.
Reasonable supplement recommendations — not a $400/month starter pack.

Questions to ask

Are you IFM-certified?
Which specialty labs do you use routinely and why?
Do you communicate with my primary care doctor?
What is the typical 6-month cost including labs and supplements?

Frequently asked

Is functional medicine covered by insurance?

Visits with an MD/DO may be partially covered; specialty labs and supplements usually are not. Superbills for out-of-network reimbursement are common.

How is it different from integrative or naturopathic medicine?

There is heavy overlap. Functional medicine emphasizes a systems framework; integrative medicine emphasizes combining conventional and complementary care; naturopathic doctors have their own licensing and training path that varies by state.
