Functional Medicine for Autoimmune Disease in Franklin, TN
By Dr. Amy Putrus-Schnell, DC CFMP — The Healing Place, Franklin, TN
The flare comes out of nowhere. One week you feel almost normal, and the next your joints ache, your energy is gone by noon, and your brain feels wrapped in fog. You push through because you have a family to care for and a life to live, but the exhaustion keeps stacking up.
Maybe you have already seen a specialist or two. Maybe you have been told your bloodwork looks “mostly normal,” handed a prescription, and sent on your way, even though you know your body is telling a different story. It is frustrating to feel this unwell and still feel like no one is connecting the dots.
You are not imagining it, and you are not alone. Many people living with an immune condition spend years bouncing between offices before anyone steps back to look at the whole picture. This page walks through what is actually happening inside the body, how a root-cause approach fits alongside your medical care, and why so many patients find that looking deeper finally gives them somewhere to start.
When the Immune System Turns Inward
Your immune defenses are built to protect you. Day and night, they scan for invaders like viruses and harmful bacteria and clear them out before they can do lasting damage. When everything works the way it should, you barely notice it happening.
An autoimmune disease develops when that same defense network loses the ability to tell “self” from “threat” and begins attacking healthy tissue by mistake. Depending on which tissue is targeted, the damage can land in the thyroid, the joints, the digestive lining, the skin, or the nerves. That is why two people with very different complaints can both be dealing with a defense system that has turned inward.
This is also why these conditions can feel so confusing. The fatigue, the inflammatory flares, the strange skin or digestive changes often seem unrelated to one another, yet they trace back to one underlying problem: a confused immune response driving chronic inflammation throughout the body.
Understanding that single thread matters, because it reframes the goal. Instead of treating each symptom as its own separate disease, the work becomes about calming and supporting the immune balance that connects them all.
How a Healthy Immune Response Is Supposed to Work
To understand what goes wrong, it helps to picture what right looks like. A healthy immune response runs on balance. Some cells ramp up the attack when a real threat appears, and other cells, called regulatory cells, apply the brakes once the danger has passed.
That braking mechanism is the part that struggles in an autoimmune condition. When the “off switch” does not work the way it should, the response stays activated, and inflammatory signaling keeps circulating long after it is needed. Over time, that persistent activity is what wears on healthy tissue.
So a functional view of immune health is not about boosting your defenses or shutting them down. It is about supporting balance, helping the regulatory side do its job so the response stays proportional. Many of the lifestyle and nutrient factors we look at influence exactly that balance.
A Plain-Language Autoimmune Disease List
There are more than 80 recognized autoimmune conditions, and they touch nearly every system in the body. Seeing them grouped together often helps people make sense of their own experience. Here are some of the most common ones we hear about:
Hashimoto’s thyroiditis targets the thyroid and is a leading driver of low thyroid function. Rheumatoid arthritis attacks the joints, causing pain, swelling, and stiffness. Lupus can affect the skin, joints, kidneys, and beyond, which is part of why it is so hard to pin down.
Celiac disease is an immune reaction to gluten that damages the small intestine. Psoriasis speeds up skin cell turnover and shows up as raised, scaly patches. Multiple sclerosis, or MS, affects the protective covering of nerves. Type 1 diabetes destroys the insulin-producing cells of the pancreas. And the inflammatory bowel diseases, including Crohn’s and ulcerative colitis, inflame the digestive tract.
These autoimmune diseases look very different on the surface, yet they share that common root in a misdirected immune response. If you see your own diagnosis on this list, take a breath. Naming the condition is the first step, and understanding what may be feeding it is where a deeper approach begins.
Who Tends to Develop an Autoimmune Disease
These conditions can affect anyone, but they do not strike at random. Autoimmune diseases as a group affect millions of people, and a striking share of them are women, often in the prime years of raising kids and building a career. That timing is part of why the fatigue and pain can feel so unfair.
Family history matters too. If a parent or sibling carries an autoimmune diagnosis, your own risk tends to be higher, though it is never a guarantee. Genetics set the stage, and then life happens on top of it: a stressful stretch, an illness, a pregnancy, a change in environment.
None of this is meant to alarm you. It is meant to validate what you may already sense, that your health story is shaped by more than one factor. Knowing you fit a recognizable pattern can actually be reassuring, because it means there are real, studied places to direct attention.
Why "Everything's Normal" Doesn't Feel Normal
One of the most common things I hear is some version of “they keep telling me I’m fine.” Standard lab panels are designed to flag disease that has already advanced, so they can miss the early, in-between patterns where you feel unwell but the numbers have not yet crossed a red line.
Conventional care is essential, and for autoimmune conditions it is often led by rheumatology, endocrinology, or another specialty that monitors disease activity and prescribes the medication you may genuinely need. That medical management has real value, and nothing here is meant to replace it.
What gets less attention is the question of why your defenses became reactive in the first place. Two people can carry the same diagnosis yet have very different drivers behind it, which is why a single standardized plan does not fit everyone equally well.
That gap, the space between “your labs are normal” and “I still feel terrible,” is exactly where a root-cause approach tries to help, working alongside your medical team rather than around it.
What a Functional Medicine Lens Adds
Functional medicine starts from a different question. Instead of asking only how to quiet the symptom, it asks what is driving the immune response and what might be keeping it switched on. The goal is a whole-body approach that looks at how your systems connect, not a single organ in isolation.
In practice, that means taking a careful history and looking at the inputs that can influence immune behavior: gut health, chronic stress, blood sugar, nutrient status, sleep, prior infections, and environmental exposures. None of these alone “causes” an autoimmune disorder, but together they shape the terrain your defenses live in.
To be clear about what this is and is not: this work does not cure or reverse an immune condition, and the research into root-cause care for autoimmunity is still developing. What it can do is help identify modifiable drivers and support your body’s overall resilience while your medical care continues.
Many patients tell me that simply having someone investigate the “why” changes how they relate to their own health. It moves them from feeling like a passenger to feeling like a participant, and that shift matters more than people expect.
Common Triggers and Root Cause Drivers Worth Investigating
No two cases look identical, but certain themes show up often enough that they are always worth a careful look. Think of these less as single causes and more as contributors that can stack up and tip a vulnerable body over the edge.
Gut health sits near the top of the list, along with chronic stress, blood sugar swings, poor sleep, nutrient gaps, hidden infections, and environmental exposures like mold or certain chemicals. Genetics load the gun, as the saying goes, but these everyday inputs are often what pulls the trigger.
The reason a root cause lens matters is that you can rarely change your genes, yet many of these other factors are modifiable. By identifying which contributors are most active for you, we can focus support where it may actually move the needle rather than guessing.
This is also why two patients with the same autoimmune disease may need very different plans. One person’s biggest driver might be gut-related, another’s might be unrelenting pressure, and a third might be running low on a key nutrient. The investigation is what tells us which.
The Gut Connection Most People Miss
If there is one system that keeps surfacing in autoimmune research, it is the gut. A large share of your immune tissue lives in the lining of your digestive tract, so the health of that barrier and the bacteria it houses has a direct line to how your defenses behave.
When the intestinal barrier becomes more permeable than it should be, sometimes called “leaky gut,” particles that belong inside the intestine can slip through and provoke an immune reaction. A review in Frontiers in Immunology describes how, in people with a genetic predisposition, increased intestinal permeability may allow environmental triggers to reach the immune system and contribute to the development of autoimmune disease. The researchers note that impaired barrier function can appear before disease onset, which is why this is such a meaningful place to look.
The digestive tract is also home to trillions of bacteria, and when that community falls out of balance it can add to the inflammatory load. Restoring a healthier balance there will not single-handedly resolve an immune condition, but it may help quiet some of the signaling that keeps your defenses on high alert.
This is why a functional workup so often starts with digestion. If a permeable barrier is part of what is keeping the response reactive, supporting it is one of the more promising levers we have.
Chronic Inflammation: The Common Thread
Almost every autoimmune disease shares one feature: ongoing, low-grade inflammation that does not fully switch off. Short bursts of inflammation are healthy and necessary, but when that response runs constantly in the background, it becomes part of the problem rather than the solution.
That chronic inflammation is often what you feel as the aching, swelling, fatigue, and flares of an inflammatory condition. It is also what slowly wears on the tissue your body is mistakenly targeting, which is why calming it matters so much.
A functional approach looks for the inputs feeding that fire. Diet, digestion, stress, blood sugar, and nutrient status all influence how much inflammation your body carries day to day. Adjusting those inputs will not erase the condition, yet it may help bring the overall burden down to a more manageable level.
Testing That Looks Deeper Than the Standard Panel
This is the part I want you to understand best, because the right testing turns guesswork into a plan. We do not chase symptoms blindly; we measure, interpret, and then decide together what makes sense for you.
A thoughtful workup often pairs conventional autoimmune and antibody labs, which confirm and monitor the diagnosis itself, with functional panels that map the terrain around it. A GI-MAP stool test, for example, examines the gut microbiome, screens for imbalances, and checks markers of digestion and intestinal health.
We also look closely at vitamin D, since adequate levels matter for a balanced immune response, and at inflammatory markers such as hs-CRP, which help gauge how much inflammation is active in the body. A broader nutrient and metabolic panel rounds out the picture, and additional comprehensive autoimmune labs may be added depending on your story.
Reading these results together, alongside your history, gives a far clearer view than any single number ever could. The point of all this lab work is never to order everything at once, but to choose the few panels that will actually shape your plan. If you want to see the specific options we use, our functional lab testing page walks through them.
Vitamin D and a Balanced Immune Response
Vitamin D deserves its own mention because it acts less like a simple vitamin and more like a messenger that helps regulate immune behavior. It influences whether your defenses lean toward a reactive, inflamed state or a calmer, more tolerant one.
Research published in the journal Nutrients found that vitamin D supports a more tolerant immune status and that circulating levels are often lower at the onset of conditions like type 1 diabetes, multiple sclerosis, and rheumatoid arthritis. The authors suggest that avoiding significant deficiency may support immune health, though vitamin D is one piece of a much larger puzzle, not a treatment on its own.
In a functional workup, we check your level rather than guess at it, then support it where it makes sense. It is a small, low-risk step that fits naturally into a whole-body approach, and it is a good example of how a modest, well-targeted change can support overall immune balance.
The Role of Stress and the Nervous System
Here is a link that often gets overlooked: your nervous system and your immune system are in constant conversation. When you are stuck in a prolonged state of stress, your body stays primed for “fight or flight,” and that ongoing signal can keep inflammatory pathways running hotter than they should.
Chronic stress will not single-handedly create an immune condition, but it can pour fuel on one that is already simmering. Patterns I see again and again involve people whose flares track closely with their hardest seasons of life, the months of poor sleep, heavy caregiving, or relentless pressure at home or work.
This is where our two sides work together. Alongside the functional workup, Dr. Anthony Putrus, DC uses a neurologically-focused approach that includes an INSIGHT scan, a non-invasive assessment that measures how your nervous system is responding to pressure. Looking at nervous system regulation next to your immune findings is part of how we care for the whole person, not just one set of labs.
Supporting a calmer, better-regulated nervous system will not replace your medical care, but it may help take some of that load off an already overactive response. For many patients, this piece turns out to be a missing part of the puzzle.
How a Root-Cause Plan Comes Together
Once testing is back, the picture usually gets clearer. The plan is built around what your results actually show, not a one-size-fits-all template, and it always assumes your medical care stays in place.
A typical protocol might focus on supporting digestion, steadying blood sugar, replenishing key nutrients like vitamin D, improving sleep, and easing the pressure on your nervous system. None of these are quick fixes, and we never frame them as a way to “beat” your diagnosis. They are levers that may help reduce the burden on an overactive immune response.
Progress here tends to be gradual and measured. We track how you feel, recheck the relevant labs over time, and adjust the protocol as your body responds. The aim is steady, sustainable change you can actually live with, not a dramatic overhaul you cannot maintain.
Throughout, we stay in our lane and respect yours. Your specialist manages the disease itself; our role is to support the surrounding terrain so your whole-body health has the best chance to stabilize.
A Story From Our Franklin Practice
In my practice, I’ve worked with patients who arrived feeling defeated after years of being told everything looked fine, even as their fatigue and flares wore them down. When we finally ran a deeper workup and looked at the gut, nutrient status, and stress load together, patterns started to surface that no single appointment had connected before.
I am always careful not to promise outcomes, because an autoimmune condition is serious and deeply individual. What I can say is that many people feel different simply because someone is finally investigating the whole picture and partnering with their medical team instead of working in a silo.
That shift in understanding, from feeling dismissed to feeling genuinely seen, is often where real momentum begins. It does not replace the hard work of managing a chronic condition, but it gives people a clearer map for it.
Living Well Alongside an Autoimmune Condition
Day-to-day habits matter more than any single supplement, and the basics carry surprising weight. Anti-inflammatory eating, consistent sleep, gentle movement, and genuine recovery time all give your body steadier ground to stand on.
For moms and dads juggling a full household, the realistic version of this is small, repeatable changes rather than a perfect routine. Trading one inflammatory habit for a supportive one, then another, adds up over the months in a way crash efforts rarely do.
It also helps to expect ups and downs. Most people living with an immune condition have better stretches and harder ones, and a flare does not mean you have failed. It means your body is asking for a little extra support while you keep the foundations in place.
None of this replaces your prescribed care or your specialist’s guidance. Think of it as the foundation underneath that care, the everyday work that may help your body manage an inflammatory condition with a little more resilience.
A Partnership With Your Medical Team, Not a Replacement
It is worth saying plainly, because it is the foundation of everything here: a root-cause approach works alongside your medical care, never in place of it. Your rheumatologist, endocrinologist, or primary provider plays a role that nothing in this office is meant to take over.
Their job is to diagnose, monitor disease activity, and prescribe the medications that may be keeping a serious condition in check. Our job is to support the surrounding terrain, the gut, the nutrient gaps, the daily load on your body, so your whole-body health has the steadiest possible foundation. The two roles complement each other.
We will never ask you to stop a prescribed treatment or skip a specialist appointment, and we encourage open communication between everyone involved in your health. The best outcomes I have seen come when conventional care and root-cause support pull in the same direction instead of competing.

Frequently Asked Questions
Can functional medicine replace my rheumatologist or specialist?
For most people, the earliest signs are respiratory or allergic — sneezing, nasal and sinus congestion, eye irritation, coughing, or a skin rash. These may be more noticeable at home and ease when you’re away.
Will this cure or reverse my autoimmune disease?
No responsible practitioner can promise that, and we never frame it that way. An immune condition is serious and individual, and the research into root-cause support is still developing. The goal is to identify modifiable factors that may help reduce the burden on your immune system while your medical care continues.
What kind of testing is involved?
A typical workup pairs conventional autoimmune and antibody labs with functional panels. That often includes a GI-MAP stool test for gut health, a vitamin D level, inflammatory markers like hs-CRP, and a broader nutrient and metabolic panel. We interpret everything together with your history.
How long before I notice a difference?
It varies, and progress tends to be gradual. Because we are supporting underlying terrain rather than chasing a quick result, many people think in terms of months, not days. We track how you feel and recheck the relevant labs over time so adjustments are based on real data.
