In short: functional medicine asks why a problem keeps happening rather than only what to call it. At Natural Medical Solutions Wellness Center in Roswell, GA, Dr. Gail Ravello, IMD, ND works this way alongside your physician, using laboratory testing to answer specific questions rather than to generate a report.
Most people arrive with a version of the same story. Something has been wrong for a while. The bloodwork came back normal. They were told nothing is wrong, or handed a prescription that manages the symptom without touching whatever produces it.
Functional medicine starts from a different question. Not "which condition fits these symptoms" but "what is going on in this person that keeps producing them". That means looking at systems rather than parts: digestion, hormones, immune function, blood sugar, sleep, stress load, nutrient status and exposure history, and how they interact. Fatigue plus bloating plus a low mood plus three kilos that will not shift is usually not four problems. It is often one, with four faces.
The second half is timing. When did it start, and what else changed that year? A course of antibiotics, a bereavement, a house move, a new medication, a pregnancy, a year of bad sleep. The history is where the answer usually is, which is why the first appointment is mostly listening.
This is worth setting out carefully, because a lot of functional medicine marketing is built on running down conventional doctors, and that is neither fair nor useful.
| Conventional workup | Functional approach | |
|---|---|---|
| The question | Do you have a diagnosable disease? | Why is this happening in you? |
| What a "normal" result means | Nothing dangerous found. Genuinely good news. | Nothing dangerous found, and the question of why you feel unwell is still open. |
| Reference ranges | Statistical ranges built to flag disease. | Same numbers, read for pattern and trend as well as threshold. |
| Typical first move | Rule out, then treat what is found. | Map the history, then test the specific question it raises. |
| Best at | Finding and managing disease. Nothing replaces it. | The person whose tests are clear and who still does not feel right. |
Those are different jobs, not competing ones. Conventional medicine is excellent at the thing it was built for, and if you have a disease you want it found by someone using those tools. What it is not designed to do is explain why an otherwise healthy person has felt below par for two years.
The same honesty applies to the content. Some of what is done under the functional medicine banner is well supported: correcting a genuine nutrient deficiency, identifying and removing a food that provokes you, treating a confirmed infection, and the unglamorous work on sleep, movement, alcohol and stress that changes more than any supplement. Some of it is not well supported, and parts of the industry sell testing and protocols that the evidence does not carry.
Our position is to say which is which as we go, including when the honest answer is that a test is not worth your money or that we are not the right people for the problem. For our part, the answer to that question is on the record: Dr. Gail Ravello is board certified by the American Naturopathic Medical Certification Board (ANMCB), holds a Ph.D. in Alternative and Integrative Medicine (PhD-IMD) from Quantum University and a Doctorate of Naturopathic Medicine (ND) from Trinity School of Natural Health, and has practised for more than 36 years. The full list of qualifications and professional memberships is on her profile. The same plain treatment is on our pages for hyperbaric oxygen and infrared sauna. It is there on detoxification as well, where the industry claims are furthest ahead of the evidence.
Longer than you are used to, and mostly conversation.
The new patient guide covers what to bring, and our wellness center page covers the building and everything offered in it.
Testing answers a question the history has already raised. It is not a substitute for asking, and a panel ordered without a question behind it mostly generates numbers to worry about.
The full menu is on the functional medicine testing page. Our post on testing before a detox shows how results actually change a plan.
Mostly the long-running and the hard to pin down: fatigue and stress-related exhaustion, digestive complaints, thyroid trouble, hormone symptoms in men and women, allergies and autoimmune conditions, brain fog and mood, cardiovascular risk, blood sugar and metabolic strain, weight that will not move, and pain that keeps returning.
The initial visit is $195. Laboratory fees are billed separately by the laboratory itself and are not part of the visit fee, so you will always be told what a panel costs before it is ordered rather than after. HSA and Flex plans can often be used, and some conventional lab work ordered during your care is commonly reimbursed. Full detail, including CareCredit, is on the finances page.
Call your insurer before your first visit and ask specifically about out-of-network reimbursement and laboratory coverage. It is a ten-minute phone call that occasionally saves a lot.
Four words get used as if they were interchangeable, and they are not. Holistic is an approach, whole person rather than one part. Naturopathic is a discipline with its own training and therapies. Integrative is a model of care, natural and conventional working together. Functional is a method: systems thinking plus targeted testing to work out what is actually going on. In this practice all four overlap constantly.
Bring your history, your labs and your questions. If we are not the right place for the problem, we will say so.
