Functional Medicine Consultation in Greenville, SC
Functional Medicine Consultation at IHP Greenville. Dr. Hendry, DAOM — functional medicine, root-cause diagnostics, personalized care. Call (864) 365-6156.
Functional medicine is a systems-biology approach to healthcare that seeks to identify and address the root causes of chronic disease — not merely manage its symptoms. At Integrative Health Partners in Greenville, SC, Dr. William Hendry conducts comprehensive functional medicine consultations that integrate advanced laboratory testing, detailed health history analysis, and evidence-based integrative protocols to resolve conditions that have persisted despite years of conventional care.
The fundamental premise of functional medicine is simple: every chronic condition has an identifiable cause. That cause is usually found in one or more of the body's core functional systems — gastrointestinal function and microbiome health, hormonal and endocrine balance, detoxification and methylation, immune regulation, neurological function, and nutritional status. Conventional medicine evaluates these systems in isolation and treats abnormalities within the current standard-of-care framework (usually a drug or procedure). Functional medicine evaluates the relationships between these systems and uses the findings to build a personalized protocol — typically a combination of dietary intervention, targeted supplementation, lifestyle modification, and when appropriate, acupuncture and Chinese herbal medicine.
Dr. Hendry's approach to functional medicine is distinctly integrative: he is one of the few practitioners in Upstate South Carolina who combines doctoral-level training in Oriental medicine with functional medicine diagnostics, an in-house herbal pharmacy, and Injection Therapy certification. This means your treatment plan draws on the full toolkit of natural medicine — not just one modality.
How Functional Medicine Consultation Works
Your functional medicine consultation begins with a 90-minute intake appointment. Dr. Hendry reviews your complete health history — including childhood illnesses, medications, surgical history, environmental exposures, diet, sleep, stress, and prior lab work. He uses a detailed symptom questionnaire that maps dysfunction across all major physiological systems.
Based on the intake, Dr. Hendry orders targeted laboratory testing — functional blood chemistry analysis, comprehensive metabolic panels, hormone panels, thyroid testing (TSH, free T3, free T4, reverse T3, thyroid antibodies), inflammatory markers (CRP, homocysteine, ferritin), gut health testing, food sensitivity testing, adrenal function assessment, nutritional deficiency screening, and heavy metals/toxin panels as indicated. These tests go far beyond what most conventional providers order, using functional reference ranges (the range of optimal health, not merely the absence of pathology) rather than standard lab reference ranges.
At your follow-up appointment, Dr. Hendry presents your results in plain language, explains what they mean for your health, and builds a comprehensive treatment protocol around the findings.
Conditions Treated with Functional Medicine Consultation
Functional Medicine vs. Conventional Care for Chronic Conditions
A patient with hypothyroidism, fatigue, brain fog, and constipation visiting a conventional practitioner may receive a TSH test, a diagnosis of hypothyroidism, and a levothyroxine prescription. The prescription may partially address the low thyroid hormone level, but if the root cause is Hashimoto's autoimmune disease (which drives over 90% of hypothyroidism in the US), and if the gut dysbiosis triggering the autoimmune reaction is untreated, and if the selenium and zinc deficiencies impairing T4-to-T3 conversion are unaddressed — the patient continues to feel unwell despite "normal" labs. Functional medicine evaluates all of these variables simultaneously and builds a protocol that addresses each one. This is why functional medicine produces lasting results for the complex, multi-system chronic conditions that challenge conventional medicine.
Research & Evidence
The functional medicine model is supported by a growing body of systems biology research. A landmark 2019 study in the Journal of Alternative and Complementary Medicine found functional medicine patients reported significantly greater improvements in health-related quality of life at 6 months compared to matched controls receiving conventional primary care. Research on the gut-brain-immune axis, the microbiome, and epigenetics has validated the functional medicine model's emphasis on environmental and dietary influences on gene expression and disease. Dr. Hendry's integration of acupuncture into his functional medicine protocols is supported by research showing that acupuncture modulates inflammatory cytokines, HPA axis function, and gut motility — directly impacting the same physiological systems that functional medicine protocols target.
Cost & Insurance Information
Functional medicine consultations at IHP are structured as initial and follow-up appointments. Laboratory testing is ordered through standard clinical labs (most insurance plans cover basic labs; advanced functional panels may be partially covered or self-pay). We provide itemized documentation for insurance reimbursement. The functional medicine consultation fee is separate from lab costs. Call (864) 365-6156 for current pricing. Many patients find that addressing root causes through functional medicine reduces their long-term healthcare costs significantly.
Treatment Timeline
Your First Appointment
Come prepared to discuss your complete health story — the more detail you can provide, the more precise Dr. Hendry's assessment will be. If you have prior labs, bring copies. Bring a current medication list including supplements. Plan for 90 minutes of focused conversation. Some patients find it helpful to journal their symptoms and key health events in the weeks before their appointment. After the intake, Dr. Hendry will order tests that can be done at a local lab — results are typically available within 1–2 weeks, at which point your follow-up consultation is scheduled.
Why Dr. Hendry for Functional Medicine Consultation
Dr. Hendry's research background (5 peer-reviewed publications, Prisma Health hospital privileges) means he reads and evaluates the functional medicine literature with a scientist's eye — not just a practitioner's intuition. His dual training in Oriental medicine and functional medicine allows him to prescribe both evidence-based herbal formulas (from our in-house pharmacy) and targeted nutritional protocols simultaneously. As an Injection Therapy-certified practitioner, he can also administer high-dose vitamin and nutrient injections as part of your functional medicine protocol — a service unavailable at most integrative practices.
