Bayou Health | Is Lyme Disease Behind Your Undiagnosed Symptoms?

By Nathan Morris, MD

As a functional medicine doctor, I quickly realized that some of the most critical conditions affecting my patients weren’t emphasized in medical school. One of the biggest? Lyme disease.

Alongside mold toxicity, Lyme is one of the root causes I see in patients struggling with chronic illness—especially when the symptoms are vague or wide-ranging. Fatigue, joint pain, cognitive issues, mood changes, insomnia—if you’re not considering Lyme, you’re going to miss it.

It’s no accident that Lyme is often called “The Great Imitator.”

What Is Lyme Disease?
Lyme disease is caused by a spirochete bacterium called Borrelia burgdorferi. Like its cousin syphilis, it can travel throughout the body, affecting joints, organs, nerves, and even the brain. But unlike syphilis, Lyme is spread through the bite of a blacklegged tick—commonly known as a deer tick—not through sexual contact.

Lyme was first recognized in 1975 in Lyme, Connecticut, when a group of children developed unexplained arthritis. The discovery was a breakthrough. But unfortunately, that was the last time this disease was simple.

Since then, Lyme has become one of the most misunderstood and underdiagnosed infections in medicine.

It’s Not Just in the Northeast
For years, Lyme was believed to be limited to the Northeastern United States. But ticks travel—via birds, deer, and other wildlife—and they don’t care about geography. Today, Lyme is found across the U.S., including in states like Louisiana where it was once considered rare.

Many patients I see here never recall a tick bite or a bullseye rash. They’ve been told they have fibromyalgia, chronic fatigue syndrome, MS, or even psychiatric illness. But in reality, Lyme is often the root cause—and it’s being missed.

Why? Because doctors aren’t testing for it. And even when they are, they may be using lab tests that frequently miss the diagnosis.

Lyme Is a Master of Disguise
Lyme disease doesn’t play by the usual rules. It can shape-shift into multiple forms, which helps it hide from both your immune system and standard blood tests. It can also lie dormant for years, then reactivate when your immune defenses are down—due to stress, illness, mold exposure, or other triggers.

Most of the patients I diagnose with Lyme don’t remember a tick bite. The famous bullseye rash? Only a small percentage ever develop it. And the first symptoms—fatigue, brain fog, joint pain—are so general that they’re often dismissed.

Even worse, mainstream lab tests are notoriously unreliable. Standard testing misses early infections and often fails to pick up chronic cases.

Better Testing Exists
Fortunately, more advanced testing options are available. IgeneX, a leader in Lyme diagnostics, offers an FDA-approved at-home collection kit (available at acudart.com) that includes a full panel for Lyme and common co-infections like Bartonella and Babesia. These tests are more sensitive, but they’re typically not covered by insurance and must be paid out of pocket.

Still, if you’re struggling with chronic, unexplained symptoms, investing in proper testing is worth it. You can’t treat what you can’t identify.

Treating Lyme Is Controversial—and Complex
Let’s say you’ve been diagnosed with Lyme, or you have strong clinical evidence pointing to it. What next?

This is where things get tricky.

Traditional infectious disease guidelines recommend 2–4 weeks of antibiotics. But in my experience, that’s rarely enough. I’ve seen patients still test positive after years of treatment. That’s because antibiotics alone aren’t a magic bullet—especially if your immune system isn’t functioning well.

Lyme treatment requires a more comprehensive, personalized strategy. You need to address not just the bacteria, but also the terrain of your body: gut health, mold exposure, stress levels, sleep quality, and more. Lyme is opportunistic—it thrives when your system is weak.

That’s why working with a Lyme-literate doctor is essential. These are practitioners trained by ILADS (International Lyme and Associated Diseases Society), who understand the complex nature of Lyme and its many co-infections. They go beyond antibiotics, using functional medicine principles to strengthen the immune system, detoxify the body, and restore balance.

The Role of Co-Infections
Many Lyme patients are also dealing with other infections carried by the same tick. Bartonella and Babesia are two of the most common, and they bring their own set of symptoms—like neurological issues, night sweats, anxiety, and more.

These co-infections further complicate the picture and must be treated alongside Lyme. Ignoring them often leads to incomplete recovery.

Why It Matters
I’ve seen Lyme misdiagnosed as multiple sclerosis, fibromyalgia, psychiatric illness, and more. I’ve treated patients who were nearly institutionalized—only to recover fully once their Lyme was properly diagnosed and treated.

Lyme is real. It’s treatable. But it’s often missed.

If you or someone you know is living with chronic, unexplained symptoms—and you’ve been told “it’s all in your head”—don’t stop searching. You deserve answers.

It might be Lyme. And with the right approach, there is hope.
