Thyroid Hormone Therapy in Davie, FL

You have been told your thyroid is normal. You still feel it is not.

If you are exhausted in a way sleep does not fix, cold when nobody else is, losing hair, constipated, foggy, and gaining weight around the middle while eating the same as always — and your lab report came back “normal” — this page is about the gap between those two sentences.

It is a common gap. Many women arrive at our office in Davie carrying the same list of symptoms through five, six, seven different specialists, and leaving each one with the same answer: your thyroid is fine.

Why does my thyroid test say normal when I feel like this?

Because “your thyroid is fine” is almost always based on a single number: TSH. TSH is not a thyroid hormone — it is the signal your brain sends the gland. What matters is what the thyroid actually produces, and whether your body can use it.

What is the difference between T4 and T3 — and why does it matter?

Your thyroid mainly makes T4, a storage form. To be used, it has to be converted into T3, the active form that tells your cells how fast to work. That conversion can fail, and the body then overproduces reverse T3, an inactive form.

What makes that conversion fail?

From perimenopause onward, the usual suspects are sustained stress, inflammation, restrictive dieting, poor sleep and shortfalls in specific micronutrients. Elevated cortisol blocks the conversion of T4 into T3, and low stored iron (ferritin) is the most frequent and most ignored deficiency at this stage.

Does the thyroid have anything to do with my hormones?

They pull on each other. When estrogen fluctuates, the availability of thyroid hormone inside your cells changes with it. If you are already on hormone therapy and not seeing results, the thing to review before changing a dose is the thyroid — with a full panel — together with cortisol and your nutritional status.

When should I see someone about this?

When feeling unwell has become your normal. Normalizing feeling bad is normalizing illness. Living tired is not normal.

“In range” and “optimal” are not the same thing

A reference range is a population average, not a target for you. It includes values that are not enough for a body to work well — which is how a woman can spend years with low ferritin that was measured, filed as “within normal limits”, and never acted on. Reading a panel for where a number sits inside the range, instead of only whether it fell inside it, is the difference between a treatment that works and one that leaves you frustrated.

One patient, with her permission and without her last name

Claudia, 46. She came in for fatigue that would not lift, difficulty losing weight, constipation and brain fog. She was in perimenopause and had started progesterone and testosterone without feeling any better. Every time her thyroid was checked, the answer was the same — your thyroid is fine — because TSH kept coming back in range.

A full evaluation looked different: active T3 low, reverse T3 high, stored iron low, cortisol elevated. The problem was not the gland itself. Her body was not converting or using what it already had.

What happens at Curativ, in Davie

A full panel, not a single number — thyroid read beyond TSH, plus cortisol and nutritional status, because those are what decide whether the thyroid hormone you have can be used.
The reading — where each value sits inside its range, and what the symptoms you walked in with say about it.
A plan that starts with the conditions, not with a prescription — addressing what is blocking conversion, so that the treatment you may already be on can finally do something.
