Thyroid Conditions We Treat

Thyroid problems rarely arrive as one tidy diagnosis. Most people who come to Wilmington Functional Medicine have a named condition plus a list of symptoms their current treatment never touched. Below are the conditions we see most, what drives each one, and how root-cause care changes the conversation for patients across Wilmington and coastal North Carolina.

How Do We Approach Thyroid Conditions?

Most thyroid care stops at the diagnosis and the prescription. We start with the question behind the diagnosis: why did this happen to this person?

A thyroid condition is the outcome. The immune system attacking gland tissue, the gland missing the raw materials it needs, the stress response that slows hormone production — those are the drivers, and they are different in every patient.

So we test for them. That usually starts with a complete thyroid panel instead of a single TSH, then widens to gut health, food sensitivities, nutrient status, and stress hormones when the picture calls for it. Testing and plan fit together in what we call the Root-Cause Thyroid Protocol. See what a complete thyroid panel measures.

What Is Hashimoto's Disease?

Hashimoto's is an autoimmune condition. The immune system attacks thyroid tissue, and the gland slowly loses its ability to make hormone. It is the most common cause of hypothyroidism in this country, and it explains why many patients feel worse even when their medication dose looks fine on paper.

What Is Hypothyroidism?

Hypothyroidism means the thyroid is not making enough hormone to run the body at full speed. Energy, metabolism, mood, digestion, cycles, and hair all slow down together. Medication replaces the missing hormone, but for many people it does not resolve everything — and the reason why matters.

More on hypothyroidism and why medication alone often leaves symptoms.

What Is Hyperthyroidism?

Hyperthyroidism is the opposite problem: too much thyroid hormone and a body stuck in overdrive. Racing heart, anxiety, weight loss despite eating well, heat intolerance, tremor. It is often driven by an immune signal or a nodule producing hormone on its own, and calming things down starts with finding that source.

What Is Graves' Disease?

Graves' disease is the autoimmune cause behind most hyperthyroidism. Antibodies mimic the signal that tells the thyroid to make hormone, so the gland never hears the message to stop. Standard treatment targets the gland or the symptom list. We are more interested in why the immune system started this.

What Are Thyroid Nodules?

Nodules are lumps in the thyroid gland, and most of them are benign. The questions that matter are whether a nodule is producing extra hormone, what the ultrasound shows, and how it changes over time. A nodule deserves clear answers, not a shrug and a six-month wait.

What If Your Labs Are Normal but You Do Not Feel Right?

This is the situation we hear about most. TSH comes back in range, and you are still exhausted, foggy, cold, and gaining weight. A standard screen can look fine while free T3, free T4, and thyroid antibodies tell a very different story.

That approach changes what a first visit looks like. You bring the symptoms and whatever lab work exists, and we look for the pattern underneath: which system is driving the problem, what has already been ruled out, and what testing would move the case forward. The goal is a short list of real answers, not another round of being told everything looks fine.

What Do These Conditions Have in Common?

More than they look on paper. Hashimoto's, hypothyroidism, Graves' disease, and nodules all sit on the same axis — the immune system, the gland itself, and the hormones that control both. Plenty of patients carry two at once: nodules on top of Hashimoto's, or overactive swings driven by an autoimmune process underneath.

They also share a starting point. Every one of these conditions is driven by something, and that something is usually findable. Food reactions, past infections, nutrient shortages, and stress show up in the background again and again, which is where proper testing earns its keep.

Not Sure Which Condition Fits?

Most people arrive with symptoms, not a diagnosis, and many have more than one thing going on — Hashimoto's on top of low iron, or low thyroid output driven by stress hormones. That is normal. Bring your symptoms and whatever lab work you already have. We will help you sort out which questions to ask next, and you can read how thyroid medication fits into the bigger picture.
