Functional medicine or your regular doctor?

This is not a choice between them. Keep your physician. The question is what functional medicine adds when your labs are normal and you still feel unwell.

The short answer

Primary care is built to diagnose and manage disease, coordinate specialists, handle acute illness, and deliver preventive screening. Functional medicine is built to investigate why a system is functioning poorly when no disease has been diagnosed — which is why it often gets used when someone feels unwell but standard labs come back normal. They answer different questions. Functional medicine is not a substitute for a primary care physician and should not replace one.

— THE TWO OPTIONS

What each one is actually for.

Functional medicine

A root-cause approach investigating why body systems are underperforming, using longer visits and broader testing than a standard appointment allows.

Choose this when

Persistent symptoms when standard labs read as normal
Digestive problems without a diagnosed disease
Fatigue, sleep disruption, and stress-response patterns
Hormone and metabolic questions needing more than a snapshot
Patients wanting a longer visit and a systems-level look

Where it falls short

Not a replacement for primary care, and not equipped for acute illness
Specialty testing is usually out of pocket
The field varies widely in rigor between practitioners
Does not manage established disease requiring pharmaceutical treatment

Primary care

Your medical home — diagnosis, disease management, prescribing, screening, referrals, and acute care.

Choose this when

Diagnosing and managing established disease
Prescription management and medication review
Preventive screening and vaccination
Acute illness and injury
Coordinating specialist referrals

Where it falls short

Visit lengths rarely allow deep investigation of vague, multi-system symptoms
Testing focuses on identifying disease rather than characterizing function
"Your labs are normal" is a common and unsatisfying endpoint when you still feel unwell

— SIDE BY SIDE

Side by side

	Functional medicine	Primary care
Core question	Why is this system underperforming?	Is there a disease, and how is it managed?
Typical visit	Long initial intake covering history, diet, sleep, stress.	Short and focused on the presenting problem.
Testing	Standard labs plus specialty functional panels.	Standard diagnostic labs and imaging.
Main tools	Nutrition, targeted supplementation, sleep, stress and lifestyle protocols.	Prescription medication, procedures, referrals.
Insurance	Visits sometimes covered; specialty testing usually not.	Generally covered.
At Meridian	Provided at both locations.	Handled by your primary care physician — keep yours, and we work alongside it.

— OFTEN THE REAL ANSWER

Keep your physician. Genuinely.

The failure mode in this field is a patient who drops their primary care physician because a functional practitioner made them feel heard, and then goes years without screening or disease management. We do not want that patient outcome and we will say so at the first visit.

Meridian does not provide primary care, general prescribing, or management of chronic disease. Prescribing within our own weight loss and functional medicine programs is a different thing from being your medical home.
Keep your annual physical, your screenings, and your prescriber.
We work alongside your physician and are glad to share findings with them.
If something we find belongs to a specialist, we refer rather than treat around it.

— WHEN IT IS NEITHER

When to see a physician rather than book with us.

Functional medicine is not the right entry point for these. Some belong in an emergency department today.

Chest pain, shortness of breath, or a sudden severe headache — emergency care
Rapid unexplained weight loss, or persistent fever
Blood in stool or urine
Symptoms of a new or uncontrolled diagnosed disease, such as diabetes
Any mental health crisis or thoughts of self-harm — contact 988 or emergency services
Pregnancy complications

— QUESTIONS

Common questions

Can functional medicine replace my primary care doctor?

They do different jobs, and they work best together. Primary care handles diagnosis, disease management, prescribing and screening — keep yours. Functional medicine investigates why systems are underperforming in the first place, which is the question a standard visit rarely has time for. Most of our patients keep both, and that is exactly how it is designed to work.

Is functional medicine covered by insurance?

Visits are sometimes covered depending on how they are billed and your plan. Specialty functional testing — DUTCH, Organic Acids, food sensitivity panels — is generally not covered and is usually out of pocket. We will tell you what applies before anything is ordered.

My bloodwork is normal but I feel terrible. What can functional medicine do?

This is the most common reason people come to us. Standard panels are designed to detect disease, and reference ranges are wide, so it is possible to be well outside your own normal while still falling inside the population range. Functional medicine looks at patterns, metabolites and system behavior rather than only whether a value crosses a diagnostic threshold. That said, normal labs sometimes genuinely mean the problem is elsewhere, and we will say so rather than keep testing.

How is Meridian's approach different from other functional medicine practices?

We work in a fixed sequence: gut and digestion first, then adrenal and stress-response, then hormones. Every one of our protocols opens that way, because hormone work started before digestion is addressed tends to underperform. It also means we sometimes tell patients that the hormone testing they came in asking for should wait.

Do you prescribe medication?

Yes, within our own programs — we prescribe GLP-1 medications and peptides as part of medical weight loss and functional medicine, in-house and inside a monitored plan rather than by online form. For medication outside those programs, your existing prescriber stays in charge, and we coordinate with them rather than working around them.

Not sure which one you need?

A visit starts with an exam, not a treatment plan. If what you need is something we do not provide, we will tell you and point you to who does.
