What Is Functional Medicine?

Medicine That Asks Why, Not Just What.

Conventional medicine is built for acute care and disease management, and it does that well. But it wasn't built for chronic, complex, multi-system problems: the fatigue no test explains, the gut that never fully heals, the hormones that stay "normal" while you feel anything but.

Functional medicine operates on a different question. Not "what disease do you have?" but "what is driving your biology toward dysfunction?" It looks at the upstream causes: gut integrity, hormone signaling, mitochondrial efficiency, nutrient status, genomic vulnerabilities, toxin burden, and how they all interact.

At Arbour Longevity, functional medicine is practiced board-certified in Family Medicine, Psychiatric Mental Health, and Functional Medicine. That's a depth of conventional and integrative training most functional medicine practices don't have. The result: a diagnostic and treatment process that is both rigorously clinical and genuinely comprehensive.

The Arbour Longevity Difference

Functional Medicine Practiced With Full Clinical Depth.

Gut Health

Most functional medicine practitioners hold a single primary certification. Our clinician holds three, Family Medicine (FNP-BC), Psychiatric Mental Health (PMHNP-BC), and Functional Medicine (Anti-Aging). This means every functional medicine patient at Arbour Longevity has access to conventional clinical rigor alongside integrative expertise, and the psychiatric dimension of chronic illness is never ignored.

Integrated with the Full Arbour Longevity System

Functional medicine at Arbour Longevity is not a standalone consultation. When your workup reveals hormone imbalances, peptide therapy is available. When it reveals mitochondrial dysfunction, NAD+ IV protocols are ready. When it reveals metabolic disease, weight loss programs integrate immediately. The whole clinic is behind every functional medicine patient, not a referral list.

Ongoing Care, Not a Single Report

Too many functional medicine practices deliver a comprehensive report and send you home to implement it alone. Arbour Longevity functional medicine model includes ongoing follow-up care, protocol adjustments as labs evolve, new interventions as the clinical picture changes, and a continuous relationship with the clinician who knows your biology from the beginning. Root cause medicine requires root cause follow-through.

Functional Medicine Focus Areas

Eleven Clinical Areas. One Interconnected System.

Every focus area below is investigated as part of the whole. Gut dysfunction drives hormone imbalance. Hormone imbalance drives brain fog. Toxin burden drives mitochondrial failure. Arbour Longevity's functional medicine approach treats the whole system, not just one symptom.

Digestive Health · Microbiome

Gut Health & Microbiome

The gut is the origin of most chronic disease. We look there first.

Intestinal permeability, dysbiosis, SIBO, inflammatory bowel disease, and microbiome imbalance affect far more than the gut. They're linked to autoimmunity, brain fog, hormone imbalances, skin conditions, and mood disorders. Arbour Longevity's gut assessment finds the specific disruptions driving your symptoms.

  • IBS / IBD
  • Bloating
  • Leaky gut
  • Dysbiosis
  • Food reactivity
OAT · Food sensitivity panel

Hormones · Adrenal · Thyroid

Hormones & Adrenal Health

Optimization beyond what a TSH and basic panel will ever show.

Thyroid dysfunction, adrenal dysregulation, cortisol imbalance, and sex hormone disruption are among the most common, and most overlooked, drivers of chronic illness. Arbour Longevity uses the DUTCH test and comprehensive thyroid panels to find what standard testing misses, then treats what it finds.

  • Hypothyroid
  • Adrenal fatigue
  • Cortisol
  • HPA dysregulation
  • Estrogen dominance
DUTCH test · Full thyroid panel

Brain · Energy · Fatigue

Brain Fog, Energy & Chronic Fatigue

The biology behind why you can't think, can't focus, can't recover.

Brain fog, cognitive decline, persistent fatigue, and burnout aren't personality traits or lifestyle failures. They are biological states with identifiable causes. Mitochondrial dysfunction, neuroinflammation, HPA axis dysregulation, and nutrient insufficiency are among the most common, and most treatable, drivers.

  • Brain fog
  • Chronic fatigue
  • Burnout
  • Poor concentration
  • Memory
OAT · Micronutrient panel

Toxins · Heavy Metals · Environment

Environmental Toxins & Heavy Metals

What your environment is doing to your biology, measured, not assumed.

Environmental toxin accumulation and heavy metal burden directly drive mitochondrial dysfunction, thyroid disruption, neurological symptoms, and immune dysregulation. Arbour Longevity's toxin and heavy metal assessment finds your specific exposures and builds a targeted detox and repletion protocol.

  • Heavy metals
  • Mold illness
  • Chemical exposure
  • Detox support
  • Immune dysregulation
Heavy metal panel · OAT

Longevity · Biological Age · Optimization

Longevity & Biological Age

Measuring and addressing your biological age, not your chronological one.

Functional medicine for longevity goes beyond fixing symptoms. It identifies the biological aging processes that determine your healthspan. Mitochondrial efficiency, oxidative stress, genomic vulnerabilities, and nutrient levels are the biggest factors in how well, and how long, you function.

  • Biological aging
  • Mitochondrial health
  • Oxidative stress
  • Genomic risk
  • Healthspan
Genomics · OAT · Full panel

Immune · Autoimmune · Food Sensitivity

Autoimmune & Inflammatory Health

Quieting an immune system that has lost its context.

Autoimmune and inflammatory conditions rarely develop without identifiable biological triggers. Leaky gut, molecular mimicry, infection history, toxin burden, and nutrient deficiency are among the most consistent root causes. Arbour Longevity's functional approach finds and treats these triggers alongside conventional care, not instead of it.

  • Hashimoto's
  • Rheumatoid
  • Inflammatory
  • Food reactivity
  • Skin conditions

Frequently Asked Questions

What Patients Ask About Functional Medicine.

What is functional medicine?
+
-

Functional medicine is a root-cause approach to health. It finds the underlying biological mechanisms driving your symptoms, instead of just managing those symptoms with medication. It uses advanced diagnostic testing, a detailed health history, and personalized protocols to address gut health, hormone imbalances, metabolic dysfunction, nutrient deficiencies, toxin burden, and how these systems interact.

What is the difference between functional medicine and conventional medicine?
+
-

Conventional medicine is excellent at diagnosing and treating acute conditions and disease. Functional medicine looks at what comes before disease: the hormone imbalances, gut dysfunction, nutrient deficiencies, inflammation, and mitochondrial inefficiency that drive chronic symptoms for years before they become diagnosable conditions. At Arbour Longevity, these two approaches work together. Our clinician's Family Medicine board certification brings conventional rigor alongside functional depth.

Where can I find a functional medicine clinician in Ann Arbor?
+
-

Arbour Longevity in Ann Arbor offers full functional medicine evaluation and ongoing care from a triple board-certified nurse practitioner: Gandhi Bhattarai, FNP-BC, PMHNP-BC, Anti-Aging/Functional Medicine BC. We serve Ann Arbor, Ypsilanti, Saline, Plymouth, Canton, and Southeast Michigan. Telehealth is available for Michigan residents for follow-up care.

What does a functional medicine evaluation include?
+
-

Arbour Longevity's functional medicine evaluation starts with a 75–90 minute intake covering your full health history and symptom timeline. Next come standard labs and advanced testing as needed, including the DUTCH test for hormone metabolites, organic acids testing (OAT) for mitochondrial and metabolic function, and genomic panels for MTHFR and other key SNPs. The result is a complete biological picture and a personalized protocol that addresses every root cause we find.

Does Arbour Longevity offer telehealth for functional medicine?
+
-

Hormone therapy replaces or adds hormones directly, like testosterone, estrogen, or progesterone. Peptide therapy signals your body to produce hormones and other compounds more efficiently, working upstream of the hormone itself. Many patients benefit from both as part of one longevity protocol: hormones restore what's deficient, while peptides can improve the signaling that makes hormone therapy work better.

How is Arbour Longevity functional medicine different from other FM clinics?
+
-

Three things set Arbour Longevity's functional medicine program apart. First, our clinician holds Anti-Aging certification alongside Family Medicine and Psychiatric Mental Health, covering the full range of chronic illness, including its neurological and psychiatric sides. Second, integration: functional medicine patients can access Arbour Longevity's hormone optimization, peptide therapy, IV therapy, and weight loss programs as one connected system. Third, ongoing care: Arbour Longevity provides continuous follow-up, not just a report and a goodbye.

Patient Experiences

Finally Finding What Was There All Along.

★★★★★

"After five years of normal labs and no answers, Arbour Longevity found three root causes in my first evaluation. The OAT panel and DUTCH test showed things no one had ever tested. I finally understood what was happening in my own body."

Caroline B. · Functional Medicine · Ann Arbor

★★★★★

"The brain fog I'd had for two years was gone within six weeks of the protocol. It turned out to be mitochondrial dysfunction and B12 depletion showing up on the organic acids test. No one had looked there before."

Thomas A. · Brain & Energy Protocol · Ann Arbor

★★★★★

"The thing that sets Arbour Longevity apart is that the functional medicine is connected to everything else. My hormone protocol and my gut protocol were designed together, not handed off to different providers who don't talk to each other."

Priya S. · Integrated Protocol · Ann Arbor

Functional Medicine in Ann Arbor

Functional medicine asks a different question than conventional primary care. Rather than matching a symptom to a prescription, it asks why the symptom is there — and keeps asking until the answer is something you can actually change.

Arbour Longevity practises functional medicine in Ann Arbor with Gandhi Bhattarai, FNP-BC, PMHNP-BC, a triple board certified nurse practitioner completing certification through the Institute for Functional Medicine. The combined certification matters here: mood, sleep and cognition are frequently the loudest symptoms, and they are too often treated in isolation from the metabolic and hormonal picture driving them.

Who tends to end up here

Most patients arrive after being told their labs are normal. They are exhausted, foggy, gaining weight, sleeping badly, or dealing with gut symptoms that no one has connected to anything. The problem is usually not that testing was wrong — it is that a standard panel is narrow, and "within range" is not the same as optimal for you.

What gets investigated

  • Full thyroid function including Free T3, Free T4 and reverse T3, not TSH alone
  • Adrenal and stress-axis markers including cortisol and DHEA-S
  • Metabolic health — fasting insulin, HbA1c, full lipid picture
  • Sex hormones with binding proteins, for both men and women
  • Inflammatory markers such as hs-CRP and homocysteine
  • Nutrient status including vitamin D, B12 and ferritin
  • Gut and microbiome factors where symptoms point there

From there you get an explanation of what the numbers mean and a plan that may involve hormone optimization, peptide therapy, IV nutrient therapy, targeted supplementation, or changes to sleep, nutrition and training — usually some combination.

Arbour Longevity is at 2217 Packard St #15 in Ann Arbor, serving Ypsilanti, Saline, Dexter, Chelsea and Washtenaw County, with telehealth available across Michigan. Your first visit is $35, applied toward your treatment plan. HSA and FSA cards accepted. Call (734) 436-3357.
