Hashimoto’s Thyroiditis Functional Medicine Care

Conditions We Support

Our doctor specializes in treating Hashimoto's thyroiditis. We use a natural approach to help manage your thyroid health.

What is Hashimoto's Thyroiditis?

Hashimoto's is an autoimmune disease, meaning that the body is attacking the thyroid gland. If you're one of the 14 million people in America who are suffering from Hashimoto's thyroiditis, you're probably wondering what you can do to help improve symptoms and get some relief.

90% of the time, the cause of hypothyroidism, or underactive thyroid, is Hashimoto's thyroiditis. The body makes antibodies (little warriors) that attack the thyroid, a butterfly-shaped gland in your throat. This can cause an underproduction of thyroid hormones and harm the hormone system that is needed to keep the body functioning properly.

Hashimoto's Thyroiditis Symptoms

Do you suspect or know that you have Hashimoto's thyroiditis? You may experience symptoms such as:

  • Fatigue
  • Weight loss
  • Brain fog
  • Constipation or “tummy troubles”
  • Muscle weakness or joint pain
  • Sleep problems
  • Sensitivity to heat or cold
  • Hair loss
  • Dry or pale skin
  • Anxiety/Depression
  • Heart palpitations
  • Hoarse/deepened voice

Triggers for Hashimoto's Thyroiditis

What can trigger or fuel an imbalance in your thyroid gland?

  • Gluten sensitivity and other food trigger
  • Viral infection such as Epstein Barr virus (EBV)
  • Plastics like BPA, phthalates, parabens
  • Small intestinal bacterial overgrowth
  • Mold toxicity
  • Low glutathione status
  • Hormonal imbalances
  • Nutrient deficiencies
  • Leaky gut
  • Blood sugar dysfunction

Hashimoto’s Labs We Commonly Review

  • TSH, free T4, free T3
  • TPO antibodies and thyroglobulin antibodies (TgAb)
  • Ferritin, vitamin D, B12, and related nutrient markers
  • Inflammatory and gut-related markers when symptoms point that direction

Conventional Hashimoto’s Care vs Root-Cause Support

Standard care monitors thyroid hormone levels and uses levothyroxine or similar replacement when hypothyroidism is present. Antibody levels confirm autoimmune thyroiditis but are not always tracked closely once replacement starts.

Functional medicine asks why the immune system is targeting thyroid tissue — looking at intestinal permeability, food triggers, infections, mold exposure, and nutrient deficiencies that commonly accompany Hashimoto’s.

How We Approach Hashimoto’s

Your evaluation reviews antibody history, symptom patterns (fatigue, cold intolerance, hair loss, brain fog), and gut symptoms. Plans may include dietary guidance, gut support, and nutrient repletion while you continue working with the clinician who manages thyroid medication.

This page focuses on Hashimoto’s. For overactive autoimmune thyroid disease, see our Graves’ disease page.

How Can Dr. Autoimmune Help?

Typically in treatment for Hashimoto's, an oral hormone medication is prescribed and can be helpful for the symptoms. However, since this drug may cause long-term damage to bones and the cardiovascular system, many people choose to find more natural ways to treat thyroiditis.

It can be frustrating trying to find help with chronic and complex conditions, which is why we have chosen to dedicate our practice to exactly that. Instead of treating the symptoms, our functional medicine approach focuses on finding the causes.

All autoimmune diseases start in the gut. We design custom plans of dietary intervention, supplements and lifestyle recommendations to help heal the gut and support the immune system. In supporting these fundamental functions of the digestive tract we can reduce inflammation and see dramatic changes in symptoms.

Finding the Root Cause

We know that autoimmunity requires 3 things to develop:

  • 1Genetic predisposition
  • 2Leaky gut (a.k.a intestinal permeability)
  • 3An environmental trigger

It All Starts in the Gut!

Our small intestine consists of 25 feet of tubing, the inside surface area being equivalent to that of a doubles tennis court!

Proteins called “tight junctions” prevent a flood of material into the gut. Low vitamin D levels coupled with inflammation in the gut starts to widen the space between cells, allowing materials (bacteria and food) to start seeping through. This triggers inflammation and as antibodies are formed they begin to target the thyroid. This is why medication may help symptoms but it can never resolve your thyroid condition.
