Functional Medicine: The Root Cause Approach
How functional medicine identifies and addresses root causes of chronic health issues through systems-based thinking, advanced testing, and personalized protocols.

What Is Functional Medicine?
Functional medicine is a systems-based approach that focuses on identifying and addressing the root cause of disease rather than just treating symptoms. Instead of asking "what drug treats this symptom," functional medicine asks "why does this patient have this symptom and what can we do to restore optimal function."
The Root Cause Framework
Most chronic health issues can be traced back to imbalances in a few core systems. Functional medicine practitioners evaluate these systems comprehensively to find where the breakdown is occurring.
- ✓Gut health — the foundation: SIBO, dysbiosis, leaky gut, food sensitivities
- ✓Hormonal balance — thyroid, adrenals, sex hormones, insulin
- ✓Detoxification — liver function, methylation, heavy metals, mold exposure
- ✓Immune dysregulation — autoimmunity, chronic infection, inflammation
- ✓Mitochondrial function — energy production, oxidative stress
- ✓Nutrient status — vitamin/mineral deficiencies that drive dysfunction
Advanced Testing
Functional medicine relies on comprehensive lab testing that goes beyond standard panels. This includes functional ranges (tighter than conventional ranges), specialty testing for gut health, organic acids, mold/mycotoxins, heavy metals, and detailed hormone panels.
The 5R Protocol for Gut Health
One of the most well-established functional medicine frameworks is the 5R gut restoration protocol, used to address the gut as the foundation of overall health.
- ✓Remove — eliminate triggers (food sensitivities, infections, toxins)
- ✓Replace — restore digestive function (enzymes, HCl, bile support)
- ✓Reinoculate — repopulate beneficial bacteria (probiotics, prebiotics)
- ✓Repair — heal the gut lining (L-glutamine, zinc, bone broth, BPC-157)
- ✓Rebalance — lifestyle factors (stress, sleep, exercise)
How BioRoot AI Applies This
BioRoot AI uses a functional medicine framework in every assessment. When you enter your symptoms, labs, and medical history, the AI identifies potential root causes, recommends targeted lab testing, and generates a personalized protocol that addresses the underlying imbalances — not just the surface symptoms.
