Have you ever experienced unexplained fatigue, weight changes, or mood swings that just don’t seem to add up?
These could be signs of a thyroid imbalance, a condition that affects your metabolism and overall well-being.
In this blog post, we’ll explore the warning signs of thyroid dysfunction, the critical labs that can help uncover these issues, and how functional medicine takes a holistic approach to optimize thyroid health beyond standard TSH testing.
By the end, you’ll have a clearer understanding of your thyroid function and actionable steps you can take to improve it.
The Importance of Thyroid Function
Your thyroid gland is a small, butterfly-shaped gland located at the front of your neck. Despite its size, it plays a massive role in regulating your metabolism, mental function, mood, and even your heart rate. Here’s a quick rundown of what your thyroid influences:
- Metabolic Rate
- Heart Rate
- Blood Pressure
- Body Temperature
- Gut Motility
- Mental Function
- Mood
- Menstruation
- Fertility
An overactive thyroid may cause symptoms like anxiety, irritability, difficulty sleeping, a racing heart, or unexplained weight loss. Conversely, an underactive thyroid could leave you feeling fatigued, foggy, and struggling with dry skin, brittle nails, and unexplained weight gain.
These symptoms can seriously affect your quality of life, and the only way to confirm a thyroid issue is through proper testing.

Essential Labs for Thyroid Function
Routine lab tests often fall short in diagnosing thyroid issues. Many standard screenings only check for Thyroid Stimulating Hormone (TSH), which doesn’t tell the full story. TSH is a hormone released by the brain to signal the thyroid gland to produce thyroid hormones (mainly T4). But TSH alone cannot provide a comprehensive view of thyroid function. For a more accurate assessment, other important markers to test include:
- T4 and Free T4
- T3 and Free T3 (Active Hormone)
- Reverse T3 (Inactive Hormone)
- Antibodies (TPO, Tg, or TRA)
These tests can reveal whether your thyroid is producing enough hormones, converting them properly, or whether autoimmunity may be impacting your thyroid function. I also measure the nutrients below because they are key to a health thyroid function along with looking for other root causes such as leaky gut syndrome, or dysbiosis or food intolerance.
- Vit A, D
- Zinc
- Omega 3 Fatty Acids
- Selenium
- Iron
How Functional Medicine Goes Beyond TSH
Even when labs come back “normal,” many people with thyroid concerns still don’t feel well. This is where functional medicine shines, offering a more holistic approach. Functional practitioners go beyond the numbers, looking at the bigger picture of thyroid health. Here’s how:
- Monitor more than just TSH: A comprehensive panel provides a clearer understanding of thyroid health.
- Optimize nutrition: Nutrients like iodine, selenium, and zinc are crucial for thyroid hormone synthesis.
- Support the conversion of T4 to T3: Ensuring that your body is efficiently converting thyroid hormones to their active forms.
- Calm inflammation & oxidative stress: Addressing inflammation that could be sabotaging your thyroid function.
- Identify & address root causes: Uncover and treat underlying issues like heavy metals, toxins, nutrient deficiencies, infections, or chronic stress.
This approach offers a deeper dive into your health and provides tailored recommendations to help you reclaim your vitality.
