A slow thyroid story is not a fast one
Hypothyroid symptoms tend to slow daily life. You may feel cold in a room others find comfortable, gain weight without a clear change in food, or fight constipation and dry skin. Hair can thin. Cycles can become heavier. Thinking may feel padded, and a nap does not fix it.
Hyperthyroid symptoms run the other direction. Heat bothers you, your heart races, your hands tremble, and weight can drop while your appetite rises. Sleep breaks. Bowels loosen. Anxiety can show up as a body feeling, which is why a heart and thyroid check belongs with your physician, not only a stress label.
Why TSH alone can miss your question
TSH is a pituitary signal telling the thyroid how hard to work. It is a useful screen, and it is not the whole conversation if you still feel cold, wired, or exhausted after being told the number is fine. The question you asked was about symptoms. A single signal from the pituitary may not answer it.
Free hormone levels describe what is available to tissues. Antibodies ask whether the immune system is involved. Reverse T3 asks whether hormone is being shunted aside during illness, calorie restriction, or heavy stress. FRI orders that wider look when your story does not match a one-line result.
What belongs on a full thyroid panel
A thyroid panel at FRI can include TSH, free T3, free T4, reverse T3, and thyroid antibodies. Each item answers a different question. TSH is the pituitary request. Free T4 is the hormone the gland releases. Free T3 is the more active form. Antibodies point toward an immune pattern.
Those names are not a score you pass or fail in this office, and FRI does not invent a private reference range. Results are read next to your heart rate, temperature, cycle, bowel pattern, and energy. Advanced bloodwork may add iron, vitamin D, or glucose markers when fatigue has more than one suspect.
Medication stays with the prescribing physician
If you already take thyroid hormone, dose changes belong to the clinician who prescribed it. Drs. Sani Kohen, D.C. and Tara Kohen, D.C. will not tell you to raise, lower, or stop that medication. Functional Medicine here can organize the panel, the history, and nutrition questions your prescriber may want to see.
Functional medicine at FRI does not replace a primary physician, endocrinologist, gastroenterologist, or mental health clinician. If nodules, a racing heart, or eye changes are part of the story, those need medical evaluation. You can also read how Hashimoto's thyroiditis differs when antibodies are the main finding.
What to expect when you are seen for Thyroid Dysfunction
A complimentary 20-minute consultation is the first step if you want to know whether FRI is the right office. Care is out of network. HSA and FSA cards are accepted, and a superbill is available when you submit a claim. The schedule is Monday–Thursday, 9–6.
Expect a history of energy, temperature, bowels, cycles, and prior thyroid results before any kit or blood draw is chosen. You review numbers in plain language. Nutrition may shift. No visit here rewrites a prescription.
Fees for a north-county patient
Out of network, superbill, HSA/FSA. The drive is unpaid. We try to earn it by not requiring you to repeat it on a blind weekly schedule. If you are improving, visits thin out. If you are not, we change the plan.
Drs. Sani and Tara Kohen are the clinicians. Use the about page and the office page before the first long drive if seeing the room helps.
Downtown Fullerton, Sunny Hills, and the university
Downtown Fullerton is walkable and social. Sunny Hills and the north streets climb. Cal State Fullerton adds a campus of walking, sitting, and backpacks. The 57 and the 91 decide how the day feels before anyone is injured. Neck pain after that freeway pattern is a common reason to look south. Knee pain in Sunny Hills is often the grade. Headaches get a neck exam and a screen for symptoms that should skip the clinic and go to emergency care.
Students and faculty sometimes want care that understands training, not only pain. Shoulder pain and a movement screen fit that request. We are not the campus health center, and we do not replace it for primary care.
A drive you should only make on purpose
From downtown and the campus, the 57 south to I-5 south is a typical path. From the east side, the 91 west to the 55 south can be cleaner. About 30 miles and 40 to 60 minutes to 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Hours are Monday through Thursday, 9 to 6. If you leave Fullerton at 4, you will sit. Book the earliest slot you can use.
Call (949) 312-1754 before you assume we are the right office. If your problem is urgent primary care, a closer physician is the better hour. If your problem is a stuck spine, a nerve, or a functional medicine question you have not gotten answered, the drive is something patients from Fullerton do make. The free 20-minute consultation can happen before a full workup.
Making fewer trips count
The home plan is the product. McKenzie self-treatment, DNS drills, and a written limit on what to do this week should travel back up the 57 with you. Hands-on care is for the parts you cannot do alone. Disc herniation and sciatica pages explain how we think about those specifically.
Thyroid and fatigue visits are scheduled so the history is not rushed, which matters more when you will not be back tomorrow. The Fullerton chiropractor page gathers the links.
Questions patients ask
Should I stop my thyroid medication before testing?
Do not stop or skip thyroid medication for a lab unless the prescribing physician tells you to. Stopping on your own can make you feel worse and can distort the very panel you hoped would clarify things. FRI coordinates the timing questions with that prescriber. Bring the dose, the brand name you were given, and the last results you have.
What if my TSH is normal and I still feel slow?
That is a common reason people ask for a wider panel. Free T4, free T3, reverse T3, and antibodies can show a pattern TSH did not describe. A normal screen does not erase your symptoms, and an extra lab does not automatically mean you need a new drug. Your physician still decides on medication.
Can a fast thyroid feel like anxiety?
A racing heart, tremor, heat, and broken sleep can feel like anxiety even when the driver is thyroid hormone running high. That possibility deserves a medical check, not a guess. FRI does not treat anxiety disorders. If worry is the main problem, keep your mental health clinician involved while thyroid questions are sorted.
Do you adjust my dose from these labs?
No. Dose changes stay with the prescribing physician or endocrinologist. FRI can explain what TSH, free T3, free T4, reverse T3, and antibodies are asking, and can talk about food, iron, and sleep as context. Functional lab testing here does not replace the person who writes the prescription.
