Insulin Resistance
Insulin resistance is the metabolic dysfunction behind most chronic disease in America — type 2 diabetes, heart disease, PCOS, fatty liver, and Alzheimer's (now called 'type 3 diabetes'). It develops silently for years before blood sugar ever goes out of range.
Insulin resistance occurs when cells stop responding normally to insulin signals, forcing the pancreas to produce more insulin to maintain blood sugar — creating a metabolic cascade that drives weight gain, inflammation, hormonal disruption, and cardiovascular risk. Signal-Based Medicine™ identifies the interconnected drivers including gut microbiome composition, cortisol dysregulation, sleep disruption, and environmental chemical exposure.
Symptoms
- Weight gain (especially belly fat)
- Inability to lose weight despite effort
- Sugar and carb cravings
- Fatigue after meals
- Brain fog
- Darkened skin patches (acanthosis nigricans)
- Increased hunger
- Elevated blood pressure
- High triglycerides
- Frequent urination
Root Causes
Insulin resistance isn't just about eating too much sugar. Your gut bacteria influence insulin sensitivity. Cortisol from chronic stress raises blood sugar. Poor sleep impairs glucose metabolism within days. Environmental chemicals like BPA mimic estrogen and disrupt insulin signaling. Treating insulin resistance with metformin alone addresses one symptom of a multi-system problem.
Testing
- Fasting insulin (not just glucose)
- HOMA-IR calculation
- HbA1c
- Fasting lipid panel with particle size
- Inflammatory markers (hs-CRP)
- Cortisol rhythm
- GI-MAP
- KureBioMap™ assessment
Treatment Approach
We identify every signal driving insulin resistance in your specific case — gut, stress, sleep, toxins, inflammation — and build a protocol that restores insulin sensitivity at its roots, not just manages blood sugar numbers.
Frequently Asked Questions
Can insulin resistance be reversed? Yes. Unlike type 1 diabetes, insulin resistance is a functional problem that responds to the right interventions. When the underlying drivers are corrected, cells can regain normal insulin sensitivity.
My fasting glucose is normal — can I still be insulin resistant? Absolutely. Fasting glucose is one of the LAST markers to go abnormal. Your body compensates by producing more and more insulin to keep glucose in range. Fasting insulin — which most practitioners don't check — often reveals resistance years before glucose elevates.
Is insulin resistance connected to PCOS? Yes. Insulin resistance is a primary driver of PCOS. Elevated insulin stimulates the ovaries to overproduce androgens, creating the hormonal imbalance that characterizes PCOS.
Do I need medication for insulin resistance? Not always. Many members reverse insulin resistance through targeted nutrition, gut restoration, stress management, and addressing environmental factors. Medications like metformin or GLP-1 agonists may be used as bridges while root causes are corrected.
