🧠 Why Your Gut Is the Control Center of Your Health
By Joe Miller, Founder 1st Optimal
Most people think of the gut as just a digestive organ. But in reality, your gastrointestinal (GI) system controls far more than food breakdown and nutrient absorption. It governs your immunity, hormone production, metabolism, brain chemistry, and even emotional resilience.
At 1st Optimal, we use a blend of clinical assessment, DNA-based stool testing, and food sensitivity labs to optimize your gut and your life. This guide will walk you through our step-by-step approach for diagnosing and fixing gut dysfunction at its root.
🔎 What You’ll Learn
- How to identify gut symptoms using the GSRS tool
- What the GI-MAP test with zonulin can reveal about your gut lining and microbiome
- The role of leaky gut, SIBO, and gut-brain axis dysfunction in systemic disease
- How food sensitivities drive weight gain, fatigue, and inflammation
- Real client success stories using 1st Optimal protocols
⚠️ Common Signs Your Gut Is Struggling
Some symptoms are obvious, like bloating or reflux. But many signs of gut dysfunction are more subtle and systemic:
| Gut-Linked Symptom | Possible Root Cause |
| Chronic fatigue | Malabsorption, immune activation |
| Brain fog & memory issues | Gut-brain axis imbalance |
| Hormonal imbalances | Estrobolome dysfunction, dysbiosis |
| Acne & rosacea | Food sensitivities, leaky gut |
| Joint pain & autoimmunity | Intestinal permeability |
| Poor recovery & sleep | Microbiome inflammation |
✅ Step 1: Take the Gastrointestinal Symptom Rating Scale (GSRS)
The GSRS is a validated tool used in both gastroenterology clinics and functional medicine. It helps quantify how your gut symptoms are affecting your life.
Instructions:
Rate each of the 15 items from 1 (no discomfort) to 7 (very severe discomfort). Tally the average in each domain.
Domains & Questions:
Abdominal Pain
- Stomach pain or cramping
- Hunger pains or gnawing sensation
- Nausea or queasiness
Reflux
- Heartburn or burning behind chest
- Acid coming back up into throat
Indigestion
- Bloating or gas after meals
- Early satiety (feeling full too quickly)
- Frequent burping or belching
Diarrhea
- Loose or watery stools
- Urgent need to use bathroom
- Feeling of incomplete bowel emptying
Constipation
- Hard stools or straining
- Going fewer than 3x/week
- Abdominal pressure due to lack of movement
Additional Symptom
- Frequent or excessive flatulence
📊 Scoring Tip: Any average domain score ≥ 3 suggests moderate to severe dysfunction and warrants further testing.
🧬 Step 2: Run a GI-MAP Test With Zonulin
What Is the GI-MAP?
The GI-MAP (Gastrointestinal Microbial Assay Plus) by Diagnostic Solutions Lab uses qPCR DNA technology to measure microbial imbalances, inflammation, and intestinal permeability.
It Tests For:
- Pathogens: H. pylori, C. diff, E. coli, Norovirus, Giardia
- Commensal flora: Akkermansia, Bifidobacteria
- Yeast overgrowth: Candida species
- Inflammation: calprotectin, sIgA
- Digestive enzymes: elastase, steatocrit
- Zonulin: biomarker for intestinal permeability (leaky gut)
Why Zonulin Matters
Zonulin controls tight junctions in your gut lining. Elevated levels mean your gut barrier is “leaking,” which allows foreign proteins, pathogens, and toxins into your bloodstream.
This triggers:
- Autoimmune responses
- Skin conditions
- Fatigue and brain fog
- Food sensitivities
- Chronic inflammation

🍽️ Step 3: Test for Food Sensitivities (Not Allergies)
Unlike IgE food allergies, food sensitivities (IgG or immune complex) can cause delayed, low-grade inflammation that shows up hours or even days later.
Common symptoms of food sensitivity include:
- Fatigue after eating
- Unexplained weight gain or fluid retention
- Brain fog or irritability
- Chronic sinus congestion
- Skin issues like eczema, psoriasis, or breakouts
🧪 At 1st Optimal, we use blood-based IgG and IgG4 panels that test for 90–200+ foods and environmental triggers.
Top reactive foods we find most often:
- Gluten (gliadin and glutenin)
- Dairy proteins (casein and whey)
- Soy, corn, and canola
- Eggs (especially whites)
- Oats, almonds, cashews, yeast
Removing these foods alongside a gut-healing protocol often leads to a dramatic improvement in symptoms.
💬 Real Client Results Using This Protocol
Lindsey A., 42, Executive:
“Brain fog and chronic fatigue were ruining my work. The GI-MAP revealed elevated zonulin and Candida. After 6 weeks on a gut protocol, I felt sharp, energized, and focused again.”
Kevin R., 37, Gym Owner:
“Daily bloating and skin breakouts were my norm. I tested high for dairy and almonds. 1st Optimal’s plan cleared my skin and helped me lose 14 pounds.”
Angela M., 39, Entrepreneur & Mom:
“No digestive issues, but I couldn’t lose weight. My gut test showed dysbiosis and cortisol issues. Their 3-phase reset worked wonders. I finally feel like I’m in control of my body again.”
