Could my thyroid be the problem?
The thyroid sets the body's metabolic pace, so when it drifts, symptoms appear everywhere: fatigue, weight change, cold intolerance, hair thinning, mood shifts, and brain fog. A TSH-only screening misses much of the story. We run a full thyroid panel — TSH, free T3, free T4, and uptake — and read it through functional ranges to catch patterns earlier than a disease-model cutoff would.
Common signs of thyroid health trouble.
- Fatigue that doesn't match your sleep
- Unexplained weight gain or difficulty losing weight
- Feeling cold when others aren't
- Thinning hair or dry skin
- Constipation or sluggish digestion
- Low mood or anxiety
Where the problem usually lives.
- 01
Suboptimal thyroid output
Values inside 'lab normal' can still be far from the functional optimum where patients feel well.
- 02
Conversion & uptake issues
TSH can look fine while free T3 — the active hormone — runs low. That's why we test the full panel.
- 03
Autoimmune activity
Autoimmune thyroid patterns are common and change the care conversation; inflammation markers help flag them.
- 04
Nutrient cofactors
The thyroid depends on nutrient cofactors that a standard checkup rarely measures.
Measured, not guessed.
Full thyroid panel
TSH plus free T4, free T3, T3 uptake, and the free thyroxine index — the panel our standard blood work includes by default.
Metabolic & inflammation context
Blood sugar, lipids, and hs-CRP tell us how the thyroid pattern is affecting the rest of the system.
Body composition testing
Tracks whether metabolic changes are showing up as muscle, fat, or water shifts.
A personalized plan — built on your results.
- Nutrition built around thyroid-relevant nutrients and steady blood sugar
- Targeted supplement guidance where labs support it
- Coordination with your prescribing physician when medication questions arise
- Scheduled retesting so the trend — not one number — drives decisions
How long until I feel better?
Every plan is written for one person, so timelines differ — but the pattern is consistent: a thorough first visit, testing within the first week or two, a results review where the plan is set, and a re-check of both symptoms and labs after a defined stretch of care. Chronic patterns that took years to build usually take months, not days, to change. What you should expect at every step is a clear explanation of what we found and why the plan says what it says.
Straight answers, in plain language.
Can functional medicine help Hashimoto's or autoimmune thyroid patterns?
Functional care focuses on the terrain around the thyroid — nutrition, blood sugar stability, inflammation, and stress load — alongside whatever medical care your prescribing physician provides. We don't replace endocrinology; we complement it with measurable lifestyle and nutritional support.
Why test more than TSH?
TSH is a signal from the pituitary, not a direct measure of active hormone. Free T3 and free T4 show what's actually available to your cells. Testing only TSH is like judging a kitchen by the order ticket instead of the food.
I'm on thyroid medication. Is this still useful?
Yes — a functional review looks at how the whole system is responding: conversion, nutrients, blood sugar, and symptoms. We coordinate with, and never replace, your prescribing physician.
