The Hidden Epidemic of Thyroid Dysfunction in Kansas City
Across Kansas City and Johnson County, thyroid disorders are one of the most underdiagnosed—and often undertreated—conditions affecting both men and women. Fatigue, weight gain, brain fog, hair loss, and mood instability are common symptoms, yet most patients are told their “labs are normal.”
At EvoHealth Functional Medicine in Overland Park, we go beyond traditional thyroid care. Rather than simply replacing hormones, we focus on why your thyroid stopped functioning properly in the first place—and how to restore optimal function through a combination of root-cause investigation and precision pharmacologic therapies when needed.
Understanding the Root Causes of Thyroid Dysfunction
Thyroid function is influenced by far more than the gland itself. Functional medicine looks upstream—to the gut, immune system, mitochondria, and even environmental exposures—to uncover what’s driving the dysfunction.
Autoimmune Thyroid Disease (Hashimoto’s or Graves’)
In most cases of hypothyroidism, the issue isn’t the thyroid gland—it’s the immune system attacking it. Hashimoto’s thyroiditis and Graves’ disease are autoimmune processes that often begin years before diagnosis. Identifying immune triggers like chronic infections, food sensitivities, or gut permeability is key to halting progression.
Poor T4-to-T3 Conversion
Many patients in Overland Park are prescribed standard T4 medication (levothyroxine), but still feel tired and foggy. Why? Because T4 must be converted into its active form, T3, in the liver and gut. Chronic stress, nutrient deficiencies (selenium, zinc, iron), and inflammation block this conversion—leaving you “biochemically hypothyroid” even if TSH looks normal.
Gut Dysbiosis and Nutrient Malabsorption
The gut-thyroid axis is central to hormone regulation. Conditions like SIBO, “leaky gut,” or dysbiosis reduce nutrient absorption (iron, iodine, B12, selenium) needed to make thyroid hormones. Functional stool testing often reveals hidden imbalances that drive persistent fatigue and inflammation.
Adrenal and Stress-Related Dysfunction
Chronic cortisol elevation from psychological or physiologic stress suppresses thyroid signaling and conversion. Many patients with low thyroid symptoms also show signs of HPA axis dysregulation—impaired stress resilience, sleep disruption, and post-exertional fatigue.
The Functional Medicine Approach at EvoHealth
Functional medicine thyroid care begins by mapping your entire metabolic and immune landscape. We don’t guess—we measure.
Advanced Testing We Use
-
Comprehensive Thyroid Panel: TSH, Free T4, Free T3, Reverse T3, thyroid antibodies
-
Micronutrient Analysis: selenium, zinc, ferritin, vitamin D, B12, iodine
-
Adrenal & Cortisol Mapping: salivary or DUTCH hormone panel
-
Gut Health & Inflammation Panels: GI-MAP stool test, zonulin, calprotectin, dysbiosis markers
-
Metabolic & Immune Markers: fasting insulin, hs-CRP, homocysteine, oxidative stress markers
This precision-based testing reveals why thyroid signaling broke down—and allows us to tailor a plan that addresses the source, not just the symptoms.
How We Restore Thyroid Function Naturally
At EvoHealth Functional Medicine in Overland Park, our thyroid restoration model is designed to normalize function at the cellular level—not just achieve “normal” lab values. We focus on the full hormone cascade: production, conversion, receptor sensitivity, and immune regulation.
Replenish Critical Nutrients
Healthy thyroid hormone synthesis depends on specific cofactors:
Iodine and tyrosine for hormone formation, selenium and zinc for T4-to-T3 conversion, and iron, magnesium, and vitamin D for receptor function.
We use advanced micronutrient panels to identify deficiencies and correct them through targeted supplementation and IV therapy, restoring the raw materials your thyroid needs to function optimally.
Improve T4-to-T3 Conversion
The conversion of T4 into its active form (T3) occurs mainly in the liver and gut. Stress, inflammation, and nutrient depletion can divert this pathway into reverse T3, an inactive blocker.
Our approach reduces inflammation, restores gut health, and supports liver detoxification—improving Free T3:rT3 ratio and enhancing tissue-level thyroid signaling.
Repair the Gut-Thyroid Axis
Up to 20% of thyroid hormone activation occurs in the gut, and most autoimmune thyroid disease begins with intestinal permeability or dysbiosis.
We utilize GI-MAP stool analysis to assess microbiome and barrier integrity, followed by personalized protocols that include gut-healing nutrients (L-glutamine, zinc carnosine), antimicrobials when needed, and reintroduction of commensal strains that aid T3 activation.
Balance the Stress Response
Chronic cortisol elevation blunts thyroid output, reduces conversion, and increases reverse T3.
We measure cortisol patterns via DUTCH or salivary panels, then restore HPA axis balance.
Modulate Autoimmunity
For Hashimoto’s or Graves’ patients, the goal is to calm—not suppress—the immune system.
We address this through low-dose naltrexone (LDN), vitamin D optimization, omega-3s, and immune-tolerant nutrition protocols to lower antibody titers and inflammation while allowing thyroid tissue recovery.
When Functional Medicine Alone Isn’t Enough: Targeted Pharmacologic Therapies
For some individuals, restoring thyroid function requires more than nutrient and lifestyle optimization. EvoHealth integrates advanced, evidence-based thyroid pharmacology when clinically indicated.
T4 + T3 Combination Therapy
Patients who fail to improve on T4-only regimens often benefit from carefully titrated combination therapy (levothyroxine + liothyronine). This supports active T3 levels at the tissue level and improves energy, mood, and metabolism.
Bioidentical and Compounded Thyroid Hormone
Customized formulations—including compounded T4/T3 or desiccated thyroid—allow for precision dosing when standard pharmaceuticals fall short.
Low-Dose Naltrexone (LDN) for Autoimmunity
For patients with Hashimoto’s or Graves’, LDN can modulate immune response, reduce inflammation, and slow antibody production.
Pharmaceutical Optimization + Functional Framework
Every medication decision is integrated within a broader context—gut health, stress management, and detoxification—ensuring a synergistic, not symptomatic, treatment approach.
