Microbiome Testing: Discover the Root Cause of Gut Issues

The truth is, most medical doctors don’t know much about nutrition, the gut microbiome, food sensitivities, micronutrients, or all the chemicals and junk in our food supply. That’s where I come in. My name is Meg Marie O’Rourke, Registered Dietitian and Functional Nutritionist for over 20 years, founder of Harmony With Food. I’m also known as Magnificent Meg and the Anti‑Diet Dietitian.

If you’ve been told to “eat less and exercise more” and it’s not working, or if you’re running to the bathroom all the time, feeling wired and tired, fatigued, and frustrated—you’re in the right place. We always say: test, don’t guess—so you can know exactly which foods, drinks, and supplements your body needs. And that starts with microbiome testing.

Why You’re Not Getting Answers From Conventional Medicine

Many of my clients come to me after years of feeling ignored or dismissed by conventional doctors. They’ve been scoped every which way, told their lab markers are “normal,” or handed a diagnosis like IBS without real solutions. Functional nutrition goes deeper—we look at the root cause using targeted functional lab testing, including gut microbiome tests and advanced analyses.

Here’s what we examine:

• Microbiome testing to detect imbalances, inflammation, and dysbiosis in your gut ecosystem

• Food sensitivity testing to uncover hidden triggers

• Micronutrient and mold testing to expose deficiencies and toxic exposures that can derail metabolism, mood, and immune function

When we test instead of guess, we uncover exactly what’s holding you back from optimal health and gut wellness.

Your Gut Health Holds the Key to Longevity

The gut microbiome is the foundation of your body’s health—digestion, metabolism, immune function, hormones, and even brain signals. Scientific research now confirms that gut dysbiosis (an unhealthy balance in your gut flora) is a major factor in aging and chronic disease. Restoring a healthy microbiome balance can reduce inflammation, support mitochondrial function, and help slow the aging process.

Patients who engage in microbiome testing see results faster—and maintain them longer—than those who continue guessing. When you understand the composition of your gut bacteria, you can match diet, lifestyle, and supplement strategies to your unique microbial profile.

What Happens When You Get a Microbiome Test

When you work with me, you’ll see exactly what’s happening inside your gut. Unlike generic labs that hand you numbers on a page, my lab partners generate color-coded, visual reports that make your results easy to understand. We examine:

• Pathogens, opportunistic bacteria, parasites, fungi, and viruses

• Beneficial vs. imbalanced microbes (diversity, richness, evenness)

• Prebiotic and probiotic indicators

• Short‑chain fatty acids, oxidative stress markers, and inflammation

• Gut immune markers, detox pathways, and metabolic biomarkers

  
  

These insights let us personalize your diet, supplement plan, and lifestyle support so you can heal your gut, regulate digestion, support your system, and finally feel like yourself again.

Functional Testing vs. Guesswork

You may see microbiome test kits online that claim to deliver results straight to your door. But beware: the best, most reliable labs are available only to licensed professionals who know how to interpret DNA sequencing, biomarkers, and microbial ecosystem data. Cheap online tests often produce incomplete or misleading results, risking wasted time, money, and confusion.

I work with CLIA‑certified labs using PCR and next-gen sequencing technology—the same DNA tools used in forensic science—so your assessment is accurate and clinically meaningful. With me, you don’t just get a microbiome test, you get interpretation, context, and a clear path forward.

Why Gut Health Impacts Everything—Even Your Mood

Your gut is often called your “second brain.” When your microbiome is out of balance, it can impact neurotransmitters, inflammation, and gut‑brain signaling. Fix the gut, and the brain often follows; balance the brain, and your gut gets stronger.

That’s why addressing gut health via microbiome testing often helps with symptoms like anxiety, depression, weight‑loss resistance, bloating, fatigue, and mood swings. It’s not “all in your head”—it’s in your gut.

Real Results from Real People

Here’s what one client shared after going through functional testing and microbiome analysis:

“After years of avoiding social events for fear of restroom emergencies, I finally got relief. The test revealed the root cause of my digestion problems. I lost 12 pounds, feel grounded again, and social life has returned. Worth every penny!”

When you identify the root cause in your gut microbiome, everything changes—your energy, confidence, digestion, and quality of life.
