Functional Medicine in Gilbert, AZ

Functional medicine is a method: find the system driving the symptom, test it broadly, treat the driver. Naturopathic medicine is a licensed profession with a four-year medical training and a preference for the least invasive effective option. At Onyx you get both, because the functional method is practiced by licensed naturopathic doctors (NMD) who can order laboratory testing and prescribe within the scope of naturopathic licensure in Arizona.

They overlap heavily and are often used interchangeably, but they are not identical. Functional medicine describes the method: investigate the system driving a symptom rather than treating the symptom alone. Integrative medicine describes the range of tools on the table, conventional and natural together. Holistic describes the scope, treating the whole person rather than one complaint. Onyx practices all three at once, which is why the same visit can end in a prescription, a nutrition plan, an acupuncture referral, or simply a clearer explanation of what your results actually mean.

In Arizona, licensed naturopathic doctors can serve in a primary care role, and some Onyx patients use us that way. Many others keep the primary care doctor they already have and add functional medicine alongside it. Either works. Your doctor will coordinate with anyone else involved in your care, and you are welcome to take your results back to them.

No. Nothing is stopped or changed without the prescribing doctor involved, and bringing your current list to the first visit is part of the workup rather than a problem. Some plans run alongside medication indefinitely. Others create the conditions for a prescriber to revisit a dose. That is a clinical decision made with you, never a condition of being seen.

Bring what you have. Recent results are reviewed and, where they are current enough, reused. Beyond routine work, Onyx has access to a full thyroid panel with antibodies and reverse T3, adrenal and cortisol testing in urine or saliva, comprehensive stool analysis, SIBO breath testing, DUTCH hormone testing, organic acid testing, a food sensitivity panel of over 200 foods, nutrient testing, and heavy metal and mold screening. Which of those you need is decided at the first visit, not before it.

Onyx is primarily cash-pay. HSA and FSA funds are accepted, and some naturopathic visits may be eligible for out-of-network reimbursement depending on your plan. Medicare generally does not cover naturopathic or functional medicine visits. Your cost has three separate parts: the visit, any lab work, which is billed by the laboratory and varies a great deal by panel, and any supplements or prescriptions. Nothing is ordered before it has been explained. Call (480) 531-2557 to go through your specific situation.

The fair answer is that it depends entirely on who is practising it, because functional medicine is a method rather than a protected title and anyone can claim it. What makes it legitimate in a given clinic is the credential behind it and the willingness to be measured. At Onyx the method is practiced by naturopathic doctors licensed by the state of Arizona; the panels are run by the same reference laboratories that serve conventional practices; and the plan is re-tested rather than assumed to be working. Where the evidence is strong your doctor will say so, where it is emerging they will say that too, and if your panel comes back unremarkable you will be told rather than sold something.

It depends on what the panels find, and any clinic that promises a date before seeing your results is guessing. What we can say is that the majority of patients notice significant improvement in the first 4 to 12 weeks. Some drivers respond quickly once they are identified. Others are slower, and a few are managed rather than resolved. What Onyx will give you at the results visit is a realistic expectation for your specific findings, and a recheck date to measure it against.
