My fingers are so stiff today that I can barely hold the 0.05-millimeter technical pen required to cross-hatch the shadows on this 325-year-old ceremonial vessel.

I am an archaeological illustrator by trade, which means my life is a series of tiny, incremental observations designed to reconstruct a whole reality from a handful of dust. It requires a level of precision that my body is currently refusing to provide. It is 65 degrees in my studio, which should be comfortable, but I am wearing a thick wool sweater and my toes feel like they have been dipped in ice water.

The Anatomy of a “Normal” Result

I am thinking about Tina. Tina is a composite of fifteen different women I have met in waiting rooms and online forums, but her story is singular in its frustration. For fifteen years, Tina has had her TSH-thyroid-stimulating hormone-checked during her annual physical.

For fifteen years, the result has hovered between 3.15 and 4.45. Each time, her doctor glances at the paper, sees that the number falls within the “reference range” (which often stretches up to 4.5 or 5.5), and tells her she is fine.

But Tina does not feel fine. Tina has gained 25 pounds despite changing nothing about her diet. Her hair is thinning at the temples, she feels like she is moving through a vat of cold molasses, and her brain fog is so thick she sometimes forgets the names of her neighbors.

In 2025, she finally convinced a locum doctor to run a slightly broader test. Her Free T3 came back at 2.25. The doctor noted it but didn’t flag it, because “normal” was technically anything above 2.0.

This is the diagnostic equivalent of looking at a single pottery shard and declaring that the entire village was wealthy. You cannot know the state of the economy from one piece of clay, and you cannot know the state of a human metabolism from one pituitary hormone.

The TSH test is a measure of what the brain thinks of the thyroid, not what the body is actually doing with thyroid hormone. The pituitary gland is the manager in the front office. When it senses that thyroid hormone levels are low, it screams (increases TSH) to tell the thyroid to get to work.

When it senses enough hormone, it whispers (lowers TSH). But the manager is often out of the loop. There are fifteen different ways the communication can break down between the office and the factory floor.

As an illustrator, I have learned that the most important part of a drawing is often the negative space-the parts I don’t draw. In medicine, the negative space is the testing that isn’t ordered.

You aren’t seeing Free T4 (the storage hormone), Free T3 (the active hormone that actually gives you energy), Reverse T3 (the “brake” that slows your metabolism during stress), or Thyroid Peroxidase Antibodies (which indicate if your immune system is attacking your thyroid).

I spent forty-five minutes this morning researching the specific pathways of T4 to T3 conversion in the liver, only to realize I had forgotten to eat breakfast. I am a hypocrite. I preach the importance of metabolic health while ignoring the fuel my own body needs to function.

I tell people to advocate for themselves, yet I often find myself shrinking in the doctor’s office, afraid to be the “difficult” patient who asks for more than the standard of care.

When the cheapest test becomes the only test, the diagnostic answer becomes whatever that test can see. Everything outside its frame is invisible to the system, even when it is painfully visible to the person living inside the body.

Taphonomic Bias in the Lab

In archaeology, we have something called “taphonomic bias.” It means that the things we find in the ground are not necessarily a representative sample of what existed; they are just the things that were durable enough to survive.

We are building a history of the patient based only on the “gold” and “bone” of the TSH, while the “cloth” and “wood” of their actual daily symptoms are left to rot.

I recall a moment when I was working on a site in the Southwest. We found a small, unremarkable stone. Most of the team wanted to toss it into the backfill, but I spent 25 minutes cleaning it with a soft brush.

It turned out to be a specialized tool for burnishing clay-a tiny piece of evidence that changed our entire understanding of the domestic life in that room. If we hadn’t looked closer, we would have missed the story.

For those who have been told for fifteen years that their fatigue is just “part of getting older” or “stress,” finding that data is the moment the sketch finally starts to look like the object.

At a clinic like

White Rock Naturopathic,

the approach to thyroid health is fundamentally different because it assumes that the patient’s experience is as valid as the lab’s data.

They don’t just look at the manager in the front office; they go down to the factory floor, they check the delivery trucks, and they look at the obstacles blocking the warehouse doors.

If your Free T3 is 2.25 and you are shivering in a 65-degree room, you do not have a “normal” thyroid, regardless of what the TSH says. You have a conversion problem. You have a cellular resistance problem. You have a life-quality problem.

The standard reference range is a statistical average of a population that is, by and large, not very healthy to begin with. It is a bell curve of the tired and the overweight. Being “normal” within a sick population is not the same thing as being well.

I often wonder how many masterpieces were never painted because the artist was too cold to hold the brush. How many books were never written because the author was trapped in a 3:15 PM brain fog that felt like a thick, grey wool blanket?

We talk about the economic cost of thyroid disease in terms of lost productivity and medication, but we rarely talk about the artistic and soulful cost of a population that is perpetually half-asleep.

Beyond the T4-Only Medication Illusion

My phone just buzzed again. Another missed call. I should probably check them, but I find myself staring at the cross-hatching on this jar. I realize that I am a bit of a contradiction.

I crave the simplicity of the ancient world-the idea that you could just be a person in a village-yet I am demanding the most complex, high-tech blood filtration analysis available to modern science. We live in a world of endocrine disruptors, chronic stress, and nutrient-depleted soil. In this world, the standard panel is a sieve with holes so large that most of us are falling through.

The T4-only medication approach is another part of this illusion. Many doctors will prescribe a synthetic T4 (like Levothyroxine) and then only monitor the TSH to see if it “balanced out.”

But if the body cannot convert that T4 into T3-which requires selenium, zinc, and a healthy liver-then the TSH will look perfect while the patient remains miserable.

We need to stop treating the lab report as the primary patient and the human being as a secondary complication. We need to start asking why a 35-year-old woman feels like a 75-year-old woman.

We need to measure the antibodies before the thyroid is already half-destroyed. We need to look at the 15 symptoms as the primary data points and the TSH as a curious, but often misleading, footnote.

I am finally going to put down my pen. My hand is cramped into a claw, and the shadow on the vessel is starting to look a bit skewed. I need to go find a heater, or a cup of tea, or perhaps a doctor who understands that a 2.25 is not a success story.
