Thyroid Health
Your Thyroid Gland Impacts Every Aspect of Your Health.
Understanding Your Thyroid
In our functional medicine practice, we know the thyroid is a cornerstone of your overall wellness. It’s not just about a single number. We take an in-depth look at your thyroid health by assessing a full range of markers. This includes free T3, free T4, TSH levels, and importantly, autoimmune markers like TPO (thyroid peroxidase antibodies) and TgAb (thyroglobulin antibodies).
Why Test These Markers?
- Free T3 and Free T4: Provide insight into the active thyroid hormones available in your body.
- TSH: Shows how your brain and thyroid are communicating.
- TPO and TgAb: Help identify whether an autoimmune process, such as Hashimoto’s, is affecting your thyroid.
Our Approach
We focus on uncovering the root causes of thyroid imbalances. That means looking beyond just the numbers—considering your nutrition, lifestyle, stress levels, and any autoimmune factors that may be at play. By checking these autoimmune markers, we can see if your immune system is impacting thyroid function.

Autoimmunity & Thyroid Dysfunction
Hashimoto’s Thyroiditis and Graves’ Disease are both caused when your immune system attacks your thyroid gland, causing inflammation and tissue destruction. Hashimoto’s Thyroiditis causes hypothyroidism. Graves’ Disease results in hyperthyroidism.
Causes of Autoimmune Thyroid Disorders
Autoimmune thyroid disorders can be caused by a variety of factors including genetic susceptibility, presence of other autoimmune illnesses, and environmental triggers such as:
- Diet
- Stress
- Toxins
- Past infections
Hashimoto’s Thyroiditis: At A Glance
- Most common form of hypothyroidism.
- 5 in 100 Americans suffer from Hashimoto’s Thyroiditis.
- Affects women more than men.
3 Stages of Hashimoto’s Disease
- Silent Autoimmunity:
- No Symptoms or tissue damage
- Positive Antibodies
- Reactive Autoimmunity:
- Symptoms
- Normal TSH
- Positive Antibodies
- Autoimmune Disease:
- Symptoms
- Elevated TSH
- Positive Antibodies
- Tissue destruction
Not all Thyroid Panels can detect Autoimmune Thyroid Disease
Identifying Autoimmune Thyroid Disease early is essential to preserving thyroid function. Allow Dr. Sarah Williams, here in Concord, MA, to help create a thyroid treatment plan just for you!
