What Is Functional Medicine?
Functional medicine is a root-cause approach to chronic illness. Rather than matching each symptom to a separate prescription, the provider tests for underlying drivers such as blood sugar dysfunction, nutrient deficiencies, and gut imbalance, then treats them through a structured program of diet change, supplementation, and supervised in-office care over several months.
The difference shows up at the first appointment. A typical primary care visit is measured in minutes; a functional medicine consultation at Active Lifestyle Medical typically runs 60 to 90 minutes, because the history matters. What you eat, how you sleep, what you take, what has already been tried: each detail narrows the search.
Testing comes next where it is genuinely useful, and the findings drive the treatment rather than a template. One patient's nerve pain traces to years of high blood sugar; another's fatigue points to nutrition. The treatment follows the finding. If that sounds like the appointment you have been waiting for, book a consultation.
Blood sugar comes up often here for a simple reason: the CDC counts more than 38 million Americans living with diabetes, and the metabolic patterns behind it show up in fatigue, nerve symptoms, and stalled weight long before anyone calls it a diagnosis.
Your labs came back normal again, and you still feel terrible. Burning feet at night, blood sugar that swings no matter what you eat, a gut that reacts to everything: none of that fits inside a seven-minute appointment. The problem is not in your head; nobody has looked deep enough yet.
Functional medicine at Active Lifestyle Medical is that deeper look, and it anchors the wellness side of our Sterling practice. Dr. Charles Arndt tests for the root causes behind stubborn chronic problems, then builds a months-long plan of supervised diet change, targeted supplementation, and in-office therapy to address them.
You keep your physician, your specialists, and your medications. We add the missing piece: a systematic search for the why, and a plan you can actually follow. Schedule a consultation to start the search.
What to Expect from Your First Functional Medicine Visit
The first visit is a long conversation, not a sales pitch. Plan on 60 to 90 minutes covering your diet, sleep, stress load, medications, and every treatment you have already tried. Testing comes second, ordered only where it will change the plan. Third, you sit down with Dr. Arndt to walk through the findings in plain language: what to change, what to take, and how often you will be seen. From there the program runs on checkpoints, with re-testing to confirm the plan is working. If we are not the right fit for your case, you will hear that at the first visit, not the tenth.
Who Benefits from Functional Medicine (and Who Should See Their Physician First)
The program fits people carrying chronic problems that have plateaued under conventional care: neuropathy that pills only dull, type 2 diabetes that needs more than a quarterly check-in, gut trouble nobody has explained, fatigue with a normal chart. It also asks something of you. The diet work is real, the timeline runs months, and patients unwilling to change how they eat rarely get their money's worth.
Functional medicine is the wrong first stop for some situations. Sudden weakness or numbness, chest pain, uncontrolled blood sugar swings, or any fast-moving symptom belongs with your physician or an emergency department first. We screen for these cases at the consultation. Chronic conditions also respond differently from person to person, so no percentage promises come with this program.
Program Cost, Insurance, and the Straight Answer
Functional medicine is usually cash-based, and pretending otherwise would not help you. What a program costs depends on its length, the testing involved, the supplement protocols, and how often you are seen, all mapped at your consultation before you commit. Insurance sometimes contributes toward specific labs or visits, and coverage differs plan to plan. Our office contacts your insurance company directly to verify what applies to your care, so the full picture, covered and not covered, is on the table before you decide.
A Program Directed by Dr. Charles Arndt
Dr. Charles Arndt, a Doctor of Chiropractic with advanced training in functional medicine, has cared for patients for more than 20 years. He leads every functional medicine case personally, from the first history interview through each round of re-testing, so the plan reflects one doctor's read on your body rather than a hand-off chain.
Conditions Functional Medicine Can Help Treat
Functional medicine earns its keep on the problems that keep coming back. These are the conditions Sterling and Potomac Falls patients most often bring to the program:
Peripheral Neuropathy →
Numbness, burning, and tingling in the feet or hands rarely improve on pills alone. The National Institute of Diabetes and Digestive and Kidney Diseases reports that up to half of people with diabetes develop peripheral neuropathy, so the program opens with metabolic testing.
Type 2 Diabetes Support →
Type 2 diabetes is one of the most common chronic conditions in the country. Our role is support, never substitution: food-first planning, activity coaching, and regular re-testing that runs alongside the care your physician directs. Every medication decision stays with your prescribing doctor.
Gut & Digestive Health →
Bloating, reflux, and unpredictable digestion often trace to food sensitivities or an out-of-balance gut. Testing identifies the triggers; an eliminate-and-rebuild plan does the repair work.
Chronic Fatigue & Low Energy →
Fatigue that survives a normal lab panel deserves a deeper search. Nutrient status, blood sugar stability, and sleep patterns are the usual suspects we test first.
Advantages of Functional Medicine With Active Lifestyle Medical VA
Plenty of clinics use the phrase root cause. Here is what separates this program:
One Doctor Owns Your Case
Dr. Charles Arndt has practiced for more than 20 years, and he personally takes your history, orders the testing, and adjusts the plan. No rotating providers, no starting over at every visit.
Testing Before Treating
Nothing goes in the plan without a reason attached. Your labs and history set the diet targets and the supplement protocol, not a one-size template.
A Program, Not a Prescription
You get structure: scheduled visits, food targets, checkpoints, and re-testing. The diet work is usually the hardest piece, and we coach you through it rather than pretending it is easy.
Built to Work with Your Doctor
Findings get shared, medication stays with your prescriber, and nothing in the program asks you to walk away from conventional care.
How a Functional Medicine Program Compares to Your Other Options
Most patients arrive having tried at least one of these paths. Here is the honest comparison.
| Option | What it involves | What it addresses | Where it fits best |
|---|---|---|---|
| Functional medicine program at Active Lifestyle Medical | Testing, supervised diet change, targeted supplementation, and in-office therapy over several months | The drivers behind the symptom, such as blood sugar dysfunction or nutrient shortfalls | Chronic problems that have stalled under symptom-only care |
| Symptom management alone | A medication that quiets the symptom while the underlying driver continues | The symptom, not the cause | Fast relief, and conditions where medication is essential; many patients run it alongside our program |
| Specialist referral (neurologist, endocrinologist) | Advanced diagnostics and disease-specific medical treatment | Diagnosis and medical management of the disease itself | New, severe, or fast-changing symptoms; the right first stop, with our program able to run alongside afterward |
General education, not medical advice for your case. When a specialist is the right first stop, we will say so at your consultation.

Functional Medicine FAQs
What is functional medicine in simple terms?
It is detective work followed by a plan. Instead of writing a prescription for each symptom, we test for what is driving the problem, then treat those drivers with supervised diet change, targeted supplementation, and in-office care. Progress is tracked over months, and the plan adjusts as your body responds.
What is the best type of doctor to see for neuropathy?
Start with your primary care physician or a neurologist to confirm the diagnosis and rule out causes that need urgent medical care. From there, the strongest setup is usually multi-disciplinary. A functional medicine program like ours works on diet, blood sugar, and nutrient factors while your physician manages the medical side. The approaches do more together than either does alone.
Can a functional medicine program help with neuropathy?
It can be part of the answer, though no single treatment cures neuropathy and anyone promising one is overselling. The best-supported step is addressing the underlying cause, which for many people means getting blood sugar under control. Our program pairs that work with supplementation and in-office therapy over several months, and results differ from patient to patient.
Is functional medicine covered by insurance?
Usually only in part, and often not at all. Much of functional medicine is cash-based, though some plans contribute toward certain labs or visits. Before you commit to anything, our office contacts your insurance company to verify what applies, so you see the full cost picture up front.
Do I stop seeing my regular doctor if I start functional medicine?
No. Keep your physician, your specialists, and every prescribed medication. Our program plays a support role alongside your medical care, and any change to a prescription belongs to the doctor who wrote it.
How long does a functional medicine program take?
Plan on months, not weeks. Chronic problems build over years, and steady progress takes repeated visits, consistent diet work, and follow-up testing. We map out the expected length at your consultation so you know the commitment before you start.
