Functional medicine is a root-cause, systems-based approach used by licensed clinicians to investigate why chronic, overlapping symptoms persist and to create a personalized plan – standard labs first, targeted specialty tests only when results will change care. Integrative medicine blends conventional care with complementary therapies (nutrition, sleep, movement, stress skills, acupuncture referrals, select herbals) to support the whole person. Alternative medicine typically refers to therapies used in place of conventional treatment; at mdPersonal Concierge Functional Medicine we favor evidence-guided, collaborative care rather than “alternative-only” approaches.
Think of your health like a house. Conventional medicine is crucial for the foundation and emergency repairs – diagnosis, prescriptions, procedures, and screening. Integrative medicine adds the daily living upgrades – nutrition, sleep, movement, stress skills, and select complementary therapies that help the house run well. Functional medicine is the forensic inspection – it traces recurring leaks back to the hidden pipes and wiring (inflammation, insulin resistance, gut–immune cross-talk, hormone and thyroid signaling), then fixes the causes so problems stop returning. Alternative medicine would be choosing a method that replaces the foundation work entirely – which we generally don’t recommend for safety.
Choose functional medicine if you have chronic, multi-system symptoms or “normal labs” that don’t match how you feel and you want a structured, investigative plan. Choose integrative medicine if you want a practical whole-person plan that pairs conventional care with lifestyle and mind–body tools. We generally do not recommend an alternative-only strategy for chronic disease or red-flag symptoms; safety and evidence come first.
Your plan is tailored to your medical history and medications. If supplements are used, we review interactions, allergies, and contraindications, and start low when appropriate. Seek urgent care immediately for chest pain, shortness of breath, severe abdominal pain, fainting, confusion, or stroke-like symptoms.
If you want a clear, science-guided plan that blends the best of conventional medicine with effective lifestyle strategies and adds functional investigation when needed. We’re here to help!
