You did the things. You found a therapist, stayed in treatment, learned the breathing techniques, examined the thought patterns. Possibly you tried a medication, and maybe a second one when the first did nothing.
And the racing heart is still there. The tremor is still there. You still wake at four in the morning with your body in a state of alarm about nothing in particular.
There are several explanations for anxiety treatment that does not work, and most of them are psychological. One of them is not, and it is checked with a blood test that costs very little and is frequently never ordered.
Why this gets missed
The symptoms are genuinely identical. Palpitations, tremor, sweating, insomnia, irritability, restlessness. Hyperthyroidism and generalized anxiety produce overlapping presentations, and no clinician can reliably separate them by listening alone.
Psychiatric symptoms get psychiatric explanations. Someone presenting with anxiety to a mental health provider enters a diagnostic frame where anxiety disorders are the working hypothesis. This is reasonable and usually correct, and it also means medical causes can go unconsidered unless something specific prompts the question.
The demographics reinforce the error. Thyroid conditions occur disproportionately in women, often in early middle age. So does the point at which women’s physical symptoms get attributed to stress or anxiety without investigation. The two tendencies compound.
Nobody is sure who ordered what. In split care, a therapist may assume the psychiatrist checked labs, the psychiatrist may assume primary care did, and primary care may have run a panel three years ago that nobody has looked at since. Reconstructing that history is part of what a reassessment at The Lieberman Center for Psychotherapeutics involves.
Normal can hide a problem. A TSH near the edge of the reference range gets reported as normal and the question is considered closed, even when the clinical picture strongly suggests otherwise.
Signs worth taking seriously
Certain features raise the probability that something medical is contributing:
- The physical symptoms dominate. Your body is in a constant state of activation, but the characteristic worry content of an anxiety disorder is less prominent. You feel physically wound up rather than mentally preoccupied.
- There was no precipitant. The anxiety appeared without an identifiable trigger, and you had no significant anxiety history before it.
- It started after forty. First onset of substantial anxiety later in life is less typical for primary anxiety disorders.
- Your weight changed without explanation.
- You cannot tolerate heat, or you sweat far more than you used to.
- Your resting heart rate is elevated, including overnight.
- Something has changed in your neck or your eyes. Swelling, fullness, a change in the appearance of your eyes, dryness, or double vision.
- You started after a pregnancy. Postpartum thyroiditis is common and routinely attributed to new parenthood.
- Therapy is not landing. The techniques work on paper and your body does not respond to them.
- Medication has not helped, or has produced side effects that seem disproportionate.
None of these is proof. Collectively they make the test worth ordering.
What to ask for
Ask your provider for a thyroid panel, and be specific about what it should include:
TSH. The first line screen.
Free T4. Adds detail that TSH alone does not provide, and is particularly relevant when the clinical picture is suggestive.
Free T3. Relevant in certain hyperthyroid presentations.
Thyroid antibodies, including thyroid peroxidase antibodies, which identify autoimmune thyroid disease and can be informative even when hormone levels sit within range.
Ask for the actual numbers rather than accepting a report that everything was normal. Reference ranges are broad, and a result sitting at the edge of the range in a person with a strongly suggestive presentation is worth discussing rather than dismissing.
If you have had labs before, ask whether they were reviewed and when.
The rest of the workup
While you are asking, several other medical contributors are worth ruling out:
- Anemia, via a complete blood count
- Vitamin B12 and vitamin D levels
- Blood glucose
- Sleep apnea, particularly if you snore, wake unrefreshed, or have been told you stop breathing
- Cardiac arrhythmia, if palpitations are prominent
- A review of current medications and supplements
That last item catches more than people expect. Stimulants, decongestants, some asthma medications, high caffeine intake, certain weight loss supplements, and thyroid hormone replacement at too high a dose all produce anxiety symptoms directly. So can withdrawal from alcohol or benzodiazepines, including in people who would not describe their use as a problem.
What happens if something turns up
If a thyroid condition is identified, treatment depends on which one. Hyperthyroidism may be managed with antithyroid medication, radioactive iodine, or surgery, with beta blockers used in the interim to reduce the physical symptoms. Hypothyroidism is treated with hormone replacement.
Improvement in psychiatric symptoms often follows once thyroid function stabilizes, though it can take weeks to months and the resolution is not always complete.
This last point deserves emphasis. Finding a thyroid problem does not mean your anxiety was never real or that you no longer need psychological care. Many people have both a thyroid condition and a genuine anxiety disorder, and treating the endocrine side while abandoning the psychological work leaves the job half done. The correct conclusion is that part of what you were carrying had a medical driver, and that part is now addressable.
If everything comes back clear
That is useful information rather than a dead end. It means the treatment plan needs revising on the psychological side: a different therapeutic approach, a different medication, a reassessment of the diagnosis, or attention to a co-occurring condition that has not been addressed.
Anxiety that has not responded to one or two attempts is common and is not evidence that you cannot be helped. It is evidence that the current plan is not the right one.
Evaluating thyroid anxiety and other medical contributors to psychiatric symptoms means considering both possibilities rather than defaulting to one.
The Lieberman Center for Psychotherapeutics is a psychiatric nurse practitioner practice providing psychiatric evaluation and medication management, with psychotherapy in selected cases. Screening for medical contributors is part of assessment, which is particularly relevant when treatment has stalled without explanation. Where a thyroid condition is identified, its management belongs with primary care or endocrinology, and the practice coordinates with them while treating the psychiatric side.
Asking for the test is not difficult and the answer is worth having either way.
