The Labs Are Normal. But Something Has Changed
One of the most common concerns patients bring to Functional Medicine of Houston involves thyroid function. The pattern is consistent: fatigue that does not resolve with rest, cold hands and feet, thinning hair, brain fog, and a general sense that something has shifted in the body.
Most of these patients have already had TSH measured — sometimes TT4 as well. Results come back normal. The patient is told the thyroid is fine. And yet something still does not feel right.
The issue may not be that the thyroid has been evaluated — it is that it may not have been evaluated completely. Standard thyroid testing captures only part of the picture. Our practice includes a functional medicine DR who looks at the full conversion process to explore what standard panels may be missing.
Why a TSH Test Alone May Not Tell the Full Story
The thyroid functions as part of a three-way system — the brain, the thyroid gland, and the body’s conversion processes. The hypothalamus signals the pituitary to produce TSH. TSH stimulates the thyroid to produce TT4. TT4 then converts into FT4, then into TT3 and finally into FT3 — which is the active form the body actually uses.
When testing evaluates only TSH and TT4, it captures the beginning of the process — not the conversion steps that follow. Those steps depend on specific micronutrients. There is also rT3 — reverse T3 — which may inhibit FT3 activity under certain conditions. Standard panels do not typically evaluate rT3.
Common experiences patients describe at this stage may include:
- Fatigue that does not resolve with rest
- Cold hands and feet
- Thinning hair and low energy
- Brain fog and difficulty concentrating
- Low mood alongside thyroid symptoms
- Symptoms that persist despite a normal TSH result
When the Doctor Says Everything Looks Normal
For many of those patients, that answer does not feel complete. They know something has changed. They just have not found a provider willing to look further.
That is the gap Functional Medicine of Houston was built to explore.
Standard thyroid panels were not designed to evaluate the full conversion process — the micronutrient dependencies, the adrenal connection, or the autoimmune markers that may be contributing to how a patient feels.
A Root-Cause Approach to Thyroid Wellness Concerns
That process begins with a thorough intake. Dr. Stowe reviews health history, prior diagnoses, medications tried, and the full arc of how symptoms have developed. From there, advanced laboratory testing may help identify specific patterns worth exploring.
What Testing May Explore
- Comprehensive 8-marker thyroid panel — TSH, Total T4, Free T4, Total T3, Free T3, Reverse T3, and when necessary, TPO antibodies, Thyroglobulin antibodies
- Adrenal and cortisol testing — stress hormone patterns that may affect thyroid function
- Micronutrient testing — deficiencies that may affect thyroid hormone conversion
- Food sensitivity panels — dietary factors that may contribute to autoimmune thyroid patterns
- Gastrointestinal testing — gut health factors that may affect thyroid hormone absorption
- Inflammatory marker panels — underlying inflammation that may affect thyroid function
The goal is a more complete picture — not a one-size-fits-all answer.
