Is Your Thyroid Waving a Red Flag?

Have you been feeling “wiped out,” gaining weight around the middle, or struggling with “brain fog”?

As an Iridology Informed Naturopath, I see this daily. Women are told their labs are “fine,” yet they feel anything but.

Because your thyroid regulates your metabolism, mood, and heart rate, any imbalance can leave you feeling fundamentally disconnected from yourself.

The “Subclinical” Gap: Why “Normal” Isn’t Enough

Most conventional doctors use a disease model. They look at your bloodwork and ask: “Are you in a state of failure?” Usually, they only test two markers: TSH and T4.

In the functional medicine world, we look for optimal health.

• The Reality: 60% of women in the U.S. have subclinical hypothyroidism. They don’t have a full-blown disease yet, but their thyroid isn’t functioning well enough for them to feel good.

• The Autoimmune Connection: Of that 60%, nearly 90% are estimated to have Hashimoto’s, an autoimmune condition where the body attacks its own thyroid.

Stop Guessing: The Comprehensive Panel

If you’re only getting your TSH checked, you’re missing the full picture. To truly see how your thyroid is performing, you need a Comprehensive Thyroid Panel.

I recommend every woman get a baseline at age 20 and then every five years—sooner if you are experiencing symptoms.

Six Essential Markers to Ask For:

· TSH (The signal from your brain)

· Free T4 (Storage hormone)

· Free T3 (The active hormone that gives you energy)

· Reverse T3 (The “brake pedal” that can slow you down)

· TPO Antibody (To check for Hashimoto’s)

· ATA Antibody (Another key autoimmune marker)

The Functional Target Zones

While a standard lab might tell you that a TSH of 4.5 is “fine,” we are looking for a much tighter window to ensure your metabolism and energy are firing correctly. Here are the “optimal” numbers you are looking for:

• TSH: We want this under 2.0. This is the signal from your brain to your thyroid; if it’s climbing higher, your brain is “shouting” at a sluggish thyroid.

• The “Active” Hormones: We look for Free T3 (3.0–4.0) and Free T4 (1.0–1.5) to be in the upper end of their respective ranges. These are the hormones that actually do the work in your cells.

• The “Brake Pedal”: Reverse T3 should be less than 15. If this is high, your body is essentially putting the brakes on your metabolism, often due to stress or chronic inflammation.

• Total Output: We monitor Total T4 (6–12) and Total T3 (100–180) to ensure your thyroid is producing enough raw material to begin with.

• 
  

I’ve found that seeing these ranges laid out side-by-side helps patients realize just how narrow the window for feeling “great” actually is compared to the very broad “normal” ranges used by most labs.

Why Antibodies Are a Non-Negotiable

I view antibodies differently than many conventional doctors. If a test shows any presence of TPO (Thyroid Peroxidase) or ATA (Thyroglobulin) antibodies, I consider that an autoimmune red flag.

In the conventional “disease model,” doctors often wait for the thyroid to be mostly destroyed before they intervene.

In my functional approach, an antibody presence is our early warning system. It tells us the immune system is misidentifying the thyroid as an enemy, and we can start addressing gut health, stress, and nutrition now to prevent the “optimal” numbers above from ever sliding into “disease” territory.

Actionable Steps to Support Your Thyroid Today

Test, Don’t Guess: Reach out to a functional or alternative practitioner who uses “functional ranges” rather than “disease ranges.” You deserve to feel optimal, not just “not sick.”

Watch the “Hidden” Disruptors:

• Sugar: Aim for less than 30g of sugar per day to keep all hormones balanced.

• Stress: High cortisol levels (our stress hormone) act like a “blocker” for thyroid hormone production.

• Blue Light: Excessive screen time at night disrupts circadian rhythms, which are intimately linked to thyroid health.

• Eat Like an Ancestor: Focus on whole foods—meat, fish, seasonal vegetables, and seeds.

  
  

Pro-tip: If you love cruciferous veggies like broccoli or cauliflower, cook them. Raw cruciferous vegetables contain goitrogens that can interfere with thyroid function in some people.

Final Thoughts

Your thyroid works harder than almost any other gland to keep you vibrant. Don’t let your symptoms be dismissed. Whether it’s through lifestyle changes, dietary shifts like going gluten-free (essential for Hashimoto’s), or proper supplementation, you can find your way back to yourself.
