Food Sensitivity Testing with Genova Diagnostics: Getting to the Root of Chronic Symptoms

A Personalized Approach at Island Health Concierge Medicine in Vero Beach, Florida

helping you understand the root of chronic systems with food testing
By Dr. Ilyadis, MD Board Certified in Internal Medicine, Pediatrics, and Lifestyle Medicine Vero Beach, Florida
Many people live for years with symptoms they are told are “normal” or “unexplained”—bloating, fatigue, headaches, joint pain, brain fog, skin issues, or stubborn weight changes. At Island Health Concierge Medicine, Dr. Ilyadis takes a different approach: we look deeper to identify the root cause, not just manage symptoms.
One of the most valuable tools we use is advanced food sensitivity testing through Genova Diagnostics, paired with a guided elimination and reintroduction plan. This approach allows us to personalize care and uncover triggers that standard lab work often misses.

What Are Food Sensitivities – and Why Are They So Hard to Identify?

Food sensitivities are delayed immune reactions that occur hours—or even days—after eating certain foods. Unlike classic food allergies (which are immediate and potentially life-threatening), food sensitivities are subtle and cumulative.
Common symptoms associated with food sensitivities may include:
  • Digestive issues (bloating, IBS, constipation, diarrhea)
  • Chronic fatige or low energy
  • Headaches or migraines
  • Join or muscle pain
  • Skin conditions such as eczema or rashes
  • Mood changes, anxiety, or brain fog
  • Inflammation and autoimmune flares
Because symptoms are delayed, many patients never connect them to food. This is where Genova Diagnostics testing becomes especially helpful.

How Genova Food Sensitivity Testing Works

Genova Diagnostics offers a clinically validated IgG food antibody assessment, which measures how your immune system responds to a wide range of commonly consumed foods.
This blood test helps us:
  • Identify foods that may be triggering inflammation
  • Understand patterns of immune reactivity
  • Create a targeted, personalized nutrition plan
Rather than guessing or eliminating foods unnecessarily, we use data-driven insight to guide next steps.

Why Testing Alone is Not Enough

Testing is only the first step. What truly sets Island Health Concierge Medicine apart is how we interpret and apply the results.

Dr. Ilyadis integrates:

  • Your medical history
  • Current Symptoms
  • Lifestyle and stress factors
  • Gut health and inflammation patterns
This allows us to determine which findings are clinically meaningful, not just “abnormal on paper.”

The Elimination Diet: A Structured, Supportive Process

Based on your results, we may recommend a short-term elimination diet, typically lasting 1–3 months. This is not a fad diet—it is a therapeutic tool designed to calm the immune system and allow the gut to heal.

The Process Includes:

  • Preparation – Clear guidance on which foods to remove and how to replace them
  • Elimination Phase – Temporary removal of reactive foods
  • Reintroduction Phase – Systematic reintroduction, one food at a time
  • Long-Term Plan – A sustainable nutrition strategy tailored to your body
Throughout this process, patients are closely supported to ensure nutritional adequacy, safety, and clarity.

Healing the Fut, Not Just Avoiding Foods

Food sensitivities are often linked to increased intestinal permeability (“leaky gut”), which allows food proteins to trigger immune responses.
At Island Health Concierge Medicine, we go further by addressing:
  • Gut barrier integrity
  • Inflammation
  • Nutrient deficiencies
  • Microbiome balance
This may include targeted nutrition, lifestyle strategies, and supplements when appropriate—always personalized, never one-size-fits-all.
