What causes Hashimoto’s Disease?

Why Hashimoto’s Needs a New Approach

Hashimoto’s thyroiditis is the most common cause of hypothyroidism in the U.S.—yet it’s often misunderstood and mismanaged. At Patients Medical in New York City, we believe you deserve more than lifelong medication. Our integrative, functional medicine approach focuses on identifying and treating the root causes of Hashimoto’s disease so you can reclaim energy, balance, and thyroid function naturally.

We don’t just suppress symptoms—we restore your health.

What Is Hashimoto’s Disease?

Hashimoto’s disease is an autoimmune thyroid condition where the immune system mistakenly attacks the thyroid gland, leading to chronic inflammation and underactive thyroid function (hypothyroidism). Over time, this damages thyroid tissue and disrupts metabolism, mood, and hormone balance.

 

Common Symptoms of Hashimoto’s Include:

Many patients suffer for years with vague symptoms before getting a proper diagnosis.

Root Causes: What Triggers Hashimoto’s Disease?

Hashimoto’s doesn’t happen randomly. Functional medicine uncovers why the immune system starts attacking the thyroid. Common triggers include:

  • Leaky Gut Syndrome: Gut permeability allows undigested proteins and toxins into the bloodstream, triggering autoimmunity.
  • Chronic Infections: Epstein-Barr Virus (EBV), H. pylori, and other stealth infections are linked to autoimmune thyroid flare-ups.
  • Nutrient Deficiencies: Low selenium, iodine, zinc, iron, and vitamin D weaken immune and thyroid function.
  • Toxin Exposure: Heavy metals, pesticides, and plastics disrupt thyroid hormone production.
  • Hormonal Imbalances: Estrogen dominance, adrenal fatigue, and PCOS can worsen thyroid dysfunction.
  • Genetics & Epigenetics: You may inherit a predisposition, but your environment and lifestyle switch genes “on” or “off.”
  • Gluten Sensitivity: Gluten can mimic thyroid tissue and provoke immune cross-reactivity.

Diagnostic Testing We Use

We go beyond the standard TSH test. Our advanced testing helps us get to the root of your Hashimoto’s:

Free T3, Free T4, Reverse T3

TPO and TG antibodies

Cortisol (saliva or urine)

Vitamin D, B12, selenium, iodine, and ferritin

Stool tests for gut dysbiosis, Candida, parasites

EBV, Lyme, and stealth infection panels

Food sensitivity and gluten reactivity testing

Heavy metal and environmental toxin screens

Integrative Treatments for Hashimoto’s Disease

Nutritional Therapy

We personalize anti-inflammatory, autoimmune-friendly diets such as AIP, paleo, or gluten-free plans to calm the immune system and support thyroid function.

  • Eliminate gluten, dairy, soy, and processed foods
  • Heal the gut lining with bone broth, glutamine, and probiotics
  • Add selenium-rich foods like Brazil nuts and seafood

Herbal & Nutraceutical Support

We use targeted supplements based on your labs:

  • Selenium and zinc
  • Myo-inositol
  • N-acetylcysteine (NAC)
  • Vitamin D3 + K2
  • Adaptogenic herbs (ashwagandha, rhodiola)
  • Antiviral herbs (lemon balm, licorice root)

All supplements are physician-selected and dosed for safety and effectiveness.

IV Vitamin Therapy

We offer customized IV infusions to boost energy, detoxification, and immune modulation.

  • Vitamin C
  • Glutathione
  • B-complex
  • Magnesium

Thyroid Hormone Optimization

We prescribe natural desiccated thyroid or bioidentical T3/T4 when needed—always tailored to your body’s needs and based on full thyroid panels.

Stress & Lifestyle Medicine

We help you manage stress with acupuncture, yoga, breathwork, and mind-body support to reduce cortisol and autoimmunity triggers.

Real Case Study: Priya’s Hashimoto’s Recovery

Priya, a 39-year-old teacher, came to us with chronic fatigue, hair loss, and cold sensitivity. Labs showed elevated TPO antibodies and low Free T3.

Her personalized 4-month integrative plan included:

  • Gluten-free, anti-inflammatory diet
  • Gut healing protocol with L-glutamine and probiotics
  • Adaptogenic herbs for adrenal support
  • Weekly IV vitamin therapy
  • Low-dose natural thyroid hormone

Her antibody levels dropped by 60%, her energy improved, and her symptoms resolved—all without synthetic drugs.

Frequently Asked Questions

It’s an autoimmune condition, often triggered by leaky gut, infections, toxins, or nutrient deficiencies.

Yes. Chronic stress raises cortisol, which suppresses thyroid function and worsens autoimmunity.

Genetics can increase your risk, but lifestyle and environment play a major role in activating the disease.

While it may not be fully “cured,” many people achieve remission and symptom-free living through functional medicine.

Gluten can mimic thyroid tissue and trigger immune attacks due to molecular mimicry.

Not always. Some improve with lifestyle changes alone, while others benefit from natural or bioidentical hormone support.

TSH isn’t enough. We test TPO/TG antibodies, Free T3/T4, Reverse T3, and more to understand your full thyroid picture.

Hashimoto’s is autoimmune-driven; hypothyroidism is the result. You can have normal TSH but still have autoimmune damage.

Diet is essential, but we often combine it with gut healing, detox, stress management, and nutrient therapy for best results.

Absolutely. We work alongside your current care to help reduce symptoms, lower antibodies, and restore optimal function.
