Hi,

Welcome to icliniq.com.

As your TSH (thyroid-stimulating hormone) is in lower range with normal values of T3 (tri-iodothyronine) and T4 (thyroxine), it is necessary to check your free T3 levels. In our body, T3 and T4 occur in free and bound form. Free-form always remains active. As your TSH is low with normal T3 and T4 values, then free T3 levels help in deciding whether you have hyperthyroidism. As you facing some symptoms of hyperthyroidism, I suggest you do these tests as soon as possible. After that, you can start taking medication for hyperthyroidism which gives you relief from your symptoms.

Investigations to be done

You need to do FT3 (free tri-iodothyronine).

Probable diagnosis

You seem to have hyperthyroidism.

Treatment plan

Your treatment can be decided after knowing T3 levels.
