Services & Specialties

What to Expect at Functional Medicine Institute (FMI)

Expect to begin with a one-on-one consultation that doubles as a medical intake — health history, goals, and often baseline labs. If a GLP-1 medication is appropriate, a licensed provider explains the titration schedule, what side effects to watch for, and how follow-ups work. Ongoing visits track progress and adjust the plan. This is a medically supervised program, not an over-the-counter fix. It's always smart to confirm your provider's license and credentials, ask about pricing up front, and bring a list of any medications or allergies.
