Thyroid Dysfunction Treatment in Tustin, CA

Thyroid trouble is not one feeling. A slow pace can leave you cold, heavy, and constipated. A fast pace can leave you hot, shaky, and awake at night. This page explains why a lone TSH result can miss the question you brought in, and what a fuller panel is built to show. For patients coming from Tustin, the office is about 16 miles away, 25–40 minutes, by the 55 south to the 73 toward Mission Viejo.

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, referrals, and the doctors

Out of network. Superbill. HSA and FSA. No referral required. We will not change a prescription from your physician. Emergency symptoms, including sudden neurologic loss, go to the ER rather than to La Alameda.

Drs. Sani and Tara Kohen practice at FRI. Their backgrounds are on the about page. The suite and gym are on the office page.

Old Town, the Legacy, and the North Tustin hills

Tustin has three different weeks. Old Town is walkable, with short blocks and a lot of sitting in cafes and small offices. Tustin Legacy, on the old base, is wide, new, and built around a car. North Tustin and the hills toward Foothill are grades, older homes, and a drive down to the 55. A low back from Legacy commuting is not a knee from a North Tustin hill. We ask which one you live in before we guess at a load.

The District and the shopping around the Legacy add standing errands on top of desk jobs. Neck pain and headaches often belong to the screen. Knee pain and hip pain show up when hill residents add steps without a plan. Plantar fasciitis shows up in people whose walking is almost all concrete between the car and a door.

South on the 55

The 55 south to the 73 is the usual path to La Alameda. About 16 miles. Twenty-five minutes is a good day. Forty is a 55 that is not cooperating. Address: 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Parking at the building. Monday through Thursday, 9 to 6.

Do not book the visit as a gap between school pickup in Old Town and a meeting. The exam needs you present, not halfway back on the freeway in your head. Call (949) 312-1754. A complimentary 20-minute consultation is available if you want to meet the doctors before an evaluation.

Chiropractic, rehab, and labs from Tustin

McKenzie Method work is a strong fit when back or neck pain has a direction that makes it better or worse. Corrective exercise is the homework. Adjustments are used when a specific joint is restricted, after the screen that says a thrust is appropriate.

Functional medicine visits cover thyroid, sleep, and gut health when those are the actual complaint. The Tustin chiropractor page collects the local routes into the three pillars.

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.
