Hypothyroidism:
Hypothyroidism Support in Salt Lake City: A Functional Medicine Approach
Your thyroid is a small gland with an enormous influence over how you feel every single day. When it is not producing enough thyroid hormone, the effects ripple across virtually every system in your body. Energy, metabolism, mood, digestion, body temperature, skin, hair, and cognitive function are all affected.
Yet many patients with hypothyroidism continue to feel unwell even after being placed on thyroid medication. Their labs say “normal,” but they still feel exhausted, foggy, and heavy. This gap between lab results and lived experience is exactly where functional medicine begins its investigation.
Understanding Hypothyroidism
Hypothyroidism occurs when the thyroid gland does not produce adequate amounts of thyroid hormones, primarily T4 (thyroxine) and T3 (triiodothyronine). These hormones regulate metabolism and cellular energy production throughout the body.
The most common cause of hypothyroidism in the United States is Hashimoto’s thyroiditis, an autoimmune condition in which the immune system mistakenly attacks thyroid tissue. Other causes include iodine deficiency, surgical removal of the thyroid, radiation therapy to the neck, and certain medications.
Common Symptoms of Hypothyroidism:
- Persistent fatigue and low energy, even after adequate sleep
- Unexplained weight gain or difficulty losing weight
- Cold intolerance and feeling cold when others are comfortable
- Constipation and sluggish digestion
- Dry skin, brittle nails, and hair thinning or loss
- Muscle weakness, aches, and joint pain
- Depression, low mood, or emotional flatness
- Brain fog, poor memory, and difficulty concentrating
- Slow heart rate
- Puffy face, especially around the eyes
- Hoarse voice
Not every patient experiences all of these symptoms, and the severity varies widely. Many people live with subclinical hypothyroidism, where lab values are borderline but symptoms are very real.
Why Standard Support Sometimes Leaves Patients Behind
The conventional approach to hypothyroidism typically involves measuring TSH (thyroid-stimulating hormone) and, if elevated, prescribing levothyroxine (synthetic T4). For many patients, this provides significant relief.
However, a substantial number of patients on levothyroxine continue to experience symptoms. There are several reasons this can happen:
- Conversion issues: The body must convert T4 to the active T3 form. Nutrient deficiencies, chronic stress, gut dysfunction, and liver health can all impair this conversion, leaving cells starved of the active hormone even when T4 levels appear adequate.
- Narrow reference ranges: Standard TSH reference ranges are broad. A TSH that is technically “normal” may still be suboptimal for an individual patient’s well-being.
- Autoimmune activity: When Hashimoto’s is the underlying cause, treating only the thyroid hormone level without addressing the immune system leaves the root cause completely untreated.
- Nutrient deficiencies: The thyroid requires iodine, selenium, zinc, iron, and specific B vitamins to function and convert hormones properly. Deficiencies in any of these can undermine treatment.
- Other hormonal interactions: Thyroid function does not operate in isolation. Adrenal health, estrogen, and progesterone levels all influence thyroid hormone activity at the cellular level.
The Salt Lake Functional Medicine Approach to Hypothyroidism
Dr. Tiffani Fries takes a comprehensive view of thyroid health that goes well beyond TSH measurement. Her goal is to understand why your thyroid is underperforming and what is needed to support it, not simply to normalize a single number on a lab panel.
Comprehensive Thyroid Testing
Rather than relying solely on TSH, Dr. Fries, DC evaluates the full thyroid picture, which may include:
- Free T4 and Free T3 to assess both the storage and active forms of thyroid hormone
- Reverse T3, which can block active T3 at the cellular level and cause hypothyroid symptoms even when other values appear normal
- Thyroid antibodies (TPO and TgAb) to identify autoimmune activity before it becomes severe
- Thyroid ultrasound when clinically appropriate
This broader picture often reveals issues that standard testing misses, and it allows for a treatment strategy that addresses the actual mechanism driving your symptoms.
Addressing Hashimoto’s as the Root Cause
Because Hashimoto’s thyroiditis is the most common driver of hypothyroidism, Dr. Fries, DC places significant emphasis on immune system support. Treating only the hormone deficiency while leaving the autoimmune attack unaddressed is like mopping the floor while the tap is still running.
Her approach to Hashimoto’s involves identifying and reducing the triggers that provoke immune reactivity, including gut permeability, food sensitivities, chronic infections, and environmental toxins. For a detailed explanation, visit our dedicated Hashimoto’s Thyroiditis page.
Nutritional and Lifestyle Support for Thyroid Health
Several nutrients are critical to thyroid function and hormone conversion. Dr. Fries, DC evaluates and addresses deficiencies in:
- Selenium: Required for T4 to T3 conversion and thyroid tissue protection
- Iodine: Essential for hormone synthesis, though excess iodine can worsen Hashimoto’s
- Zinc and iron: Both necessary for thyroid hormone production and conversion
- Vitamin D: Strongly linked to autoimmune regulation and thyroid antibody levels
- B vitamins: Support adrenal and thyroid function simultaneously
Dietary changes may also include an anti-inflammatory protocol and elimination of common thyroid disruptors such as gluten, which shares structural similarities with thyroid tissue and can provoke cross-reactive immune responses in Hashimoto’s patients.
Adrenal Support
The adrenal glands and thyroid are deeply interconnected. Chronic stress and adrenal dysfunction can suppress thyroid hormone output, impair conversion, and reduce cellular sensitivity to thyroid hormone. Addressing adrenal health is often a prerequisite to achieving stable thyroid function.
Gut Health and Thyroid Function
Approximately 20 percent of T4 to T3 conversion occurs in the gut. An imbalanced microbiome, intestinal permeability, or chronic gut inflammation can meaningfully impair thyroid hormone availability. Many patients with hypothyroidism who have suboptimal gut health see significant improvement when gut function is restored.
What to Expect from Your Care
Your first appointment with Dr. Fries, DC will be a thorough conversation about your health history, symptoms, current medications, and lifestyle. She will review any prior lab work and determine what additional testing would provide the most useful picture.
From there, she will develop a personalized plan that addresses your specific pattern of dysfunction. Follow-up appointments allow for adjustments as your body responds and your labs evolve. This is not a one-appointment fix. It is a collaborative process of investigation, support, and refinement until you are genuinely feeling well.
Frequently Asked Questions About Hypothyroidism
Can functional medicine replace my thyroid medication?
Not necessarily, and we never recommend stopping thyroid medication without physician supervision. For some patients, addressing the root causes leads to a natural improvement that allows medication to be reduced over time. For others, medication remains appropriate alongside functional support. Dr. Fries, DC coordinates closely with your primary care or endocrinology provider.
Why do I still feel hypothyroid if my TSH is normal?
TSH is only one piece of the picture. Suboptimal T3, poor hormone conversion, cellular resistance, or nutritional deficiencies can all produce hypothyroid symptoms even when TSH falls within range. A more complete panel often reveals what a TSH-only approach misses.
Is Hashimoto’s the same as hypothyroidism?
Not exactly. Hashimoto’s is an autoimmune condition that damages the thyroid gland over time, eventually leading to hypothyroidism. It is the most common cause of hypothyroidism in the US, but not all hypothyroidism is caused by Hashimoto’s. Identifying which is driving your situation changes the treatment approach significantly.
What foods are harmful to thyroid health?
Processed foods, excess sugar, and refined carbohydrates promote systemic inflammation that can worsen thyroid function. For Hashimoto’s patients specifically, gluten and in some cases dairy can trigger immune reactivity. Goitrogenic foods like raw cruciferous vegetables are often overstated as a concern, though moderation when iodine status is already low makes sense.
Ready to Understand Your Thyroid More Deeply?
If you have been told your labs are normal but you still do not feel like yourself, or if you have been on thyroid medication and want to address the underlying cause, we are here to help.
