Because Feeling Good Starts in Your Gut.

Could your gut be the reason you don’t feel your best?

The gut plays a central role in digestion, immune function, hormone balance, detoxification, and inflammation serving as the foundation of overall health. When the gut is inflamed or imbalanced, it can contribute to bloating, food sensitivities, fatigue, skin concerns, thyroid dysfunction, hormonal imbalances, and even autoimmune conditions.

We begin by restoring balance in the gut to support the entire body from the inside out so you can finally feel truly optimal.

About Our Approach

​

Find the Root Cause. Heal Your Gut. Feel Like Yourself Again.

If you’ve been told that everything looks “normal” even though you don’t feel well  you’re not alone.
Many people are frustrated by years of symptoms, test results that don’t explain anything, and quick fixes that never last. That’s where Gut Geeks is different.

We practice Functional Medicine, an approach focused on identifying and correcting the root cause of your symptoms rather than just masking them. We use advanced lab testing and personalized coaching to uncover what’s really going on inside your body  and guide you with a clear, science-based plan to restore balance and long-term wellness.

If you’ve tried every supplement or diet and still don’t feel your best, it’s time for a new approach. Gut issues often go far deeper than food choices alone. Through evidence-based testing, functional nutrition, and individualized coaching, we help you understand what your body truly needs to heal and thrive.

The Gut Geeks combines functional lab analysis, targeted nutrition strategy, lifestyle guidance, and one-on-one coaching support to help you achieve real, lasting results.

Over the next few months, you’ll have four personalized follow-up sessions. These calls provide accountability, ongoing education, and plan adjustments to ensure you stay on track and continue improving.

Frequently Asked Questions

What is the Gi-Map Test?

The GI-MAP (Gastrointestinal Microbial Assay Plus) is an advanced stool test that analyzes the DNA of the bacteria, yeast, parasites, and viruses living in your gut.
Unlike standard stool tests, the GI-MAP uses qPCR technology (quantitative polymerase chain reaction) to provide a detailed, highly accurate view of your microbiome and digestive function.

It looks at:

  • Levels of healthy and harmful bacteria

  • Presence of parasites, viruses, or yeast overgrowth

  • Inflammation and immune markers (like calprotectin and secretory IgA)

  • Digestive enzyme output and intestinal health

This test helps identify the root cause of symptoms such as bloating, IBS, reflux, constipation, diarrhea, skin issues, and fatigue.

What is the IgG Food Sensitivity Test?

​​

The IgG Food Sensitivity Test measures delayed immune reactions to specific foods.
While traditional allergy tests look for immediate IgE reactions, this test identifies foods that trigger inflammatory or immune responses over time, which can contribute to bloating, headaches, fatigue, skin problems, and other chronic symptoms.

The test measures IgG antibody levels to a wide range of common foods, helping us determine which foods your body may be reacting to  and guiding your personalized nutrition plan.

Why are these test used together?

​Gut health and food sensitivities are deeply connected.
The GI-MAP helps identify imbalances, infections, and inflammation within the gut, while the IgG test shows which foods may be irritating the system or contributing to inflammation.
Used together, they provide a comprehensive picture of what’s driving your symptoms and how to restore balance.

How are these test done?

​​Both tests are done at home.

  • The GI-MAP involves a small stool sample that’s collected in a kit and mailed directly to the lab.

  • The IgG test is a simple blood spot or venipuncture sample.

You’ll receive detailed instructions and a prepaid shipping label with your kit.

What kind of symptoms can these tests help with?

​​​Common symptoms that benefit from this type of testing include:

  • Bloating, gas, and abdominal discomfort

  • Constipation or diarrhea

  • Hormone Issues

  • Food sensitivities and intolerances

  • Fatigue or brain fog

  • Acne, eczema, or rosacea

  • Inflammation 

  • Autoimmune flare-ups

  • Anxiety or mood changes related to gut imbalance

We’ll use your data to design a plan focused on:

  • Restoring healthy gut bacteria

  • Reducing inflammation

  • Healing the gut lining

  • Adjusting your diet and supplements to support long-term balance

"Working with Dr. Doug played an important role in helping me return to a high level of performance. In 2023, I was diagnosed with an autoimmune condition affecting my spine that significantly disrupted my ability to train and compete as a collegiate runner. After graduating, I returned to running recreationally while on a biologic medication, but I experienced side effects and later lost insurance coverage for the treatment in early 2025.After moving to Jacksonville, I scheduled a discovery appointment with Dr. Doug after learning about his work with athletes and complex recovery cases and his functional medicine informed approach. From the very first visit, Dr. Doug took the time to understand my full history and how my condition was impacting my training, recovery, and overall resilience. I appreciated his research informed, data driven approach and the way he explained everything clearly.As part of my care, Dr. Doug utilized functional medicine based diagnostics to help assess contributing factors and guide a more tailored, individualized plan. Rather than guessing or relying on one size fits all solutions, we used this information to support recovery and gradually rebuild my capacity to train.

Within a few months, I noticed meaningful improvements in my mental clarity, energy, and ability to tolerate consistent physical activity again. Over the following months, I continued progressing toward personal and athletic goals, including qualifying for the Ironman 70.3 World Championships and becoming a Pilates instructor.

I am very grateful for Dr. Doug’s guidance, communication, and performance focused approach throughout this process. If you are an athlete or active individual looking for a thoughtful, individualized approach to recovery and performance, I highly recommend Dr. Doug"

"Hi, I’m Randy, and I proudly served in the U.S. Navy for over 13 years. After leaving the service, I struggled with lower back discomfort, sinus issues, and sleep problems that were taking a toll on my work, my marriage, and my overall wellbeing.

When I returned home to Jacksonville and began working with Dr. Douglas Suffield, everything finally clicked. For the first time, I felt truly heard and understood.

Dr. Doug used functional medicine testing and a personalized, root-cause approach to explain what was contributing to my symptoms. He gave me a clear plan forward—one that actually made sense and felt tailored to me. Over time, my sleep improved, my energy returned, and I started to feel like myself again. The positive changes strengthened my marriage and restored the quality of life I had been missing for years.

I’m sharing my story because I want other veterans and first responders to know that real support exists. Dr. Doug’s dedication, insight, and compassion made a meaningful difference in my life, and I believe his approach can help many others find the same hope and direction."

Through functional medicine assessments, personalized nutrition support, and clear guidance, Dr. Doug helped me understand what was contributing to my symptoms and how to support my body in a healthier way.Over time, my sleep improved, my mental clarity increased, and my overall sense of wellbeing began to return. What I appreciated most was that I finally had a plan, support, and a practitioner who truly listened.

I am deeply grateful for Dr. Doug and his commitment to bringing education, support, and hope to the veteran community."
