Thyroid specialist in Springfield, MO — hypothyroidism testing & treatment
Thyroid care that goes deeper than one TSH.
Exhausted, cold, foggy, losing hair, gaining weight — and told your thyroid is fine. Most physicals check one marker, TSH. It is genuinely possible for that one number to look acceptable while the rest of your thyroid picture, including autoimmune activity, is clearly abnormal.
This place is truly amazing. Teresa helped me after I couldn’t answers for years with severe migraines. The staff is very nice and helpful too.

Start here
What thyroid care actually looks at.
The plain version first: your thyroid sets your metabolic pace, and when it slows, a single TSH test often misses it. Real thyroid care reads the full panel and treats the pattern. Three terms come up constantly and get confused — here is the difference.
Hypothyroidism
An underactive thyroid
The gland isn’t making enough hormone, so everything runs slow — energy, weight, mood, temperature. The most common thyroid problem, and the one most often missed on a lone TSH.
Hashimoto’s
The autoimmune cause
The immune system attacking the thyroid — the reason behind most hypothyroidism. It shows up in antibodies that a standard panel usually never orders.
Free T3 / Free T4
The active hormone
The usable thyroid hormone your cells actually run on. TSH is the pituitary’s signal, not the hormone itself, which is why it can read normal while T3 sits low.
In their own words
What an underactive thyroid actually feels like
“I am tired no matter how much I sleep.”
“I am cold when nobody else is.”
“My hair is falling out.”
“I cannot think clearly through the fog.”
“I gained weight without changing anything.”
“My skin is dry and my nails break.”
“I am constipated and bloated.”
“My mood has flattened out.”
Every one of these is measurable. None of them is something you have to live with because someone called it normal.
Drawn at our in-office lab · Walk-in lab draws Mon–Thu 7:30–2, no appointment needed
What we measure
One marker cannot describe a whole gland
TSH is a signal from your brain, not a measurement of thyroid hormone itself. We test the hormones your body is actually making and converting, plus the antibodies that reveal Hashimoto — the most common cause of low thyroid function, and one a TSH-only check routinely misses.
TSH
Free T4
Free T3
Reverse T3
TPO antibodies
Thyroglobulin antibodies
Vitamin D
Ferritin
The full thyroid panel — not a lone TSH.
Free T3, free T4, reverse T3 and Hashimoto antibodies, because a normal TSH routinely sits on top of a thyroid that is not converting hormone properly.
A normal TSH does not close the case.
Most patients arrive having already been told their thyroid is fine. That result is one marker of several, and on its own it explains very little.
How it works
Three steps to a real thyroid answer.
You help build this plan from the first step — you choose how deep the testing goes, you see what came back, and nothing gets treated without you understanding why.
Step 01
Choose your testing depth
You pick the tier that fits your history, so you are not paying for markers you do not need or missing the ones that matter.
Simple, full, or Hashimoto
Step 02
See how your system connects
Thyroid, sex hormones, and insulin are connected. Teresa shows you how yours are interacting instead of handing you a lab printout.
One-hour results review
Step 03
Start treatment, then confirm it
Your dose is set to your labs and your symptoms, then rechecked, so progress is measured rather than assumed.
Thyroid care sits in an odd gap — too routine for some specialists, too involved for a quick visit. Who you see shapes how deep the testing goes. The honest landscape.
Primary care (PCP)
Where most thyroid symptoms first come up and a TSH gets checked.
Panel depth
Usually TSH alone
Checks antibodies
Rarely
Treats to
Whether TSH is in range
Endocrinologist
The hormone specialist, typically reached by referral for complex cases.
Panel depth
Deeper, case by case
Checks antibodies
When indicated
Treats to
Guideline ranges
Med spa / wellness bar
May sell thyroid support supplements without a real workup.
Panel depth
Minimal, if medical at all
Checks antibodies
No
Treats to
A product, not your labs
Dedicated hormone clinic
Where you are
A practice that reads the full thyroid picture as routine, not exception.
Panel depth
Free T3, free T4, reverse T3
Checks antibodies
Hashimoto’s, routinely
Treats to
How you feel plus the full panel
You don’t always need an endocrinologist, and you don’t need a referral to be seen here. What matters is whether someone runs more than a TSH, checks for the autoimmune cause, and treats how you feel rather than one number in range.
Who qualifies
Should you get your thyroid looked at more closely?
A normal TSH doesn’t mean the question is settled. Whether a deeper look is worth it comes from your symptoms and your history — here is the honest shape of who it tends to fit.
Likely a fit if
You have the classic signs — fatigue, weight gain, cold, hair thinning, brain fog — with a “normal” TSH.
You were diagnosed and medicated but still don’t feel right.
Only a TSH was ever run, and free T3, free T4, and antibodies never were.
Thyroid disease runs in your family and you want the full picture, not a single marker.
Not the right starting point if
You’re pregnant — thyroid matters a lot then, but that testing should be coordinated with your OB.
You’re stable and feel well on current treatment; there may be nothing to change.
You want a specific thyroid drug on demand without testing; that isn’t how it’s prescribed here.
Your symptoms point elsewhere entirely — the same panel usually shows where to look instead.
Not sure a deeper look is warranted? That’s exactly what the assessment and a full thyroid panel are for.
Who you'll actually see
Teresa Mealy, APN
There is no rotating staff here. Teresa is the founder and the only clinical provider, which means the person who reads your labs is the same person who builds your thyroid care plan and the same person you see at every follow-up.
“I am only a consultant. YOU are the leader.”
APN — Advanced Practice Nurse
Licensed in Missouri and Florida
Medically supervised with a board-certified physician
Thyroid problems are among the most commonly missed, and it shows in what patients write afterward about finally being tested properly. All public reviews, quoted exactly as published.

In making an appointment with Teresa I found out that all my years of odd symptoms were in fact, Hashimotos. Now I am on my journey towards healing and it would never of happened if not for Teresa…

Common questions
Thyroid testing questions, answered plainly.
My TSH was normal. Could I still have a thyroid problem?
Yes, and it is common. TSH is a pituitary signal, not a direct measure of thyroid hormone. Free T3, free T4, reverse T3, and thyroid antibodies can all be abnormal while TSH still reads inside the reference range.
Do you test for Hashimoto?
Yes. We run TPO and thyroglobulin antibodies, which is how Hashimoto is identified. It is the most common cause of hypothyroidism and it is routinely missed when only TSH is checked.
Can thyroid problems cause weight gain and fatigue?
They can, and they often overlap with insulin resistance and sex-hormone changes — which is why we test all three together rather than chasing them one at a time.

Often connected to
One system, not separate problems.
These rarely show up alone. Teresa treats them together, in one plan, rather than as separate departments.
It all starts with the $299 Total Health Assessment — a full lab panel, a one-hour results review, and a plan built around you. The fee credits fully toward any program you start.
