Is hyperthyroidism difficult to diagnose?

can hyperthyroidism be difficult to diagnose? I have many many thyroid nodules, and consistant low THS .17 but t3 is usually ok and most recently my t4 was only .9 this is a week following an episode of tachycardia that lasted hours. I have had fertility issues, crazy red itchy eyes, anxiety, tachycardia, nervousness and bouts of diarrhea that don t seem to have a cause. Because My recent testing is only borderline for T4 my doctor feels the tachycardia was not related to the thyroid. but could not t4 have been even lower when the tachycardia happeended. the test was a week later.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

If you have multiple thyroid nodules do USG thyroid, if any abnormalities present then they will advice you a FNAC test. Sometimes thyroid test doesn't show any significant changes but the thyroid related symptoms may present. We call it as subclinical hyperthyroidism. Do the above mentioned tests and follow up with reports or you can also visit a surgeon or a general physician.

Hope I have answered your query. Let me know if I can assist you further.

hello, i had mono about 12 months ago. it took forever (9-10 months) to me to feel like myself again. a few months after i was diagnosed with mono i became hyperthyroid and had panic attacks, heart palpitations, and anxiety , that went away. now, i just get a bad taste in my mouth (back of throat ) a few times a day. I also find it difficult to have a full 8 hour sleep (something that has never bothered me before). could i still be slightly hyperthroid?

I am a 69 yr old female, have had a non functioning thyroid for 45 years, no surgery. I have manintained a normal level of TSH with last maybe 10 years prescription of 1.25. Four months ago the blood test result TSH level was 2.09. This month, suddenly the TSH level is 0.114, and T4,Free of 1.61. The PA wants to reduce my Synthroid prescription, saying I am hyperthyroid. I asked about having a T3 test, and she said not until I was on the new prescription. I have no symptoms of hyperthyroidism, no fast heart rate or heart palpitations, shakes, heavy breathing. I think there could be more to the diagnosis, not willing to reduce my prescription. Also, the last 4 months, I have been taking Vitamin E, Biotin, and newly started Vit D supplement, 2000. The blood test shows D-deficient 22. , previous test same. Do you really think I’m hyperthyroid? Do I start the new prescription of 1.125? Thank you.
