You're exhausted despite sleeping enough. Your joints ache without explanation. Brain fog makes simple tasks difficult. You've seen multiple doctors, but all your tests come back "normal." You're told it's just stress.
Does this sound familiar?
If you're experiencing unexplained symptoms that conventional medicine hasn't been able to diagnose or treat effectively, you may be among the millions of Americans silently struggling with Autoimmune Disease.
Autoimmune Disease occurs when your immune system—designed to protect you—mistakenly attacks your body's own healthy tissues. Recent groundbreaking research reveals that autoimmune disease affects approximately 15 million Americans, or 4.6% of the population, and these numbers are rising by 3-12% annually.
Perhaps most concerning: women are nearly twice as likely as men to develop autoimmune disease, and one-third of people with one autoimmune condition will develop additional autoimmune diseases.
Autoimmune Disease is often called "the great imitator" because symptoms can mimic many other conditions. On average, patients visit four different healthcare providers over 4.5 years before receiving an accurate diagnosis.
If you're experiencing multiple symptoms from this list, especially if they've persisted despite conventional treatment, it's worth exploring whether autoimmune disease might be at the root of your health challenges.

Understanding the truth about autoimmune disease is essential for getting proper care:
Myth 1: "If your bloodwork is normal, you're fine."
Reality: Standard blood tests often miss early-stage autoimmune disease. Autoantibodies can be present years before showing up on conventional testing. Functional Medicine uses more comprehensive testing to detect problems earlier.
Myth 2: "Autoimmune Disease is entirely genetic—there's nothing you can do."
Reality: While genetics play a role, environmental triggers and intestinal permeability are equally important—and within your control. As we say in Functional Medicine: genetics set the stage, but lifestyle writes the script.
Myth 3: "You'll need medication forever."
Reality: While medication has an important place, most people experience significant improvement through Functional Medicine approaches that address root causes and many are able to wean their medications. The goal is to support—not suppress—proper immune function.
Myth 4: "Diet doesn't really matter for autoimmune disease."
Reality: Diet profoundly impacts autoimmune disease by triggering immune responses, modulating inflammation, affecting gut barrier integrity, and influencing the microbiome. What you eat either feeds inflammation or fights it.
Myth 5: "Leaky gut isn't real."
Reality: Intestinal permeability is well-established in scientific literature with thousands of peer-reviewed studies documenting its role in autoimmune disease. Researchers have identified specific mechanisms and biomarkers that regulate intestinal barrier function.
At Arbor Health Functional Medicine & Psychiatry, we take a different approach to autoimmune disease. Rather than simply suppressing your immune system with medication, Functional Medicine seeks to identify and treat the root causes driving immune dysfunction.
You Don't Have to Accept a Lifetime of Symptom Management
If you're experiencing unexplained symptoms or struggling with an autoimmune diagnosis, you deserve more than just symptom suppression. Functional Medicine offers a comprehensive approach that addresses the root causes of immune dysfunction, with the goal of restoring balance and optimal function.
We understand that healing from autoimmune disease takes time and requires addressing multiple factors. Your autoimmune condition didn't develop overnight, and recovery is a journey. But with the right approach, many people experience significant improvements in symptoms, inflammatory markers, and quality of life.
Take the First Step
Don't wait for symptoms to worsen. If you recognize yourself in this article—if you're tired of being told "all your tests are normal" when you clearly don't feel normal—it's time to explore a functional medicine approach.
Your body is not attacking itself without reason. There are root causes behind autoimmune disease, and addressing them can change the trajectory of your health
