I did my thyroid test last week for the first time because my body weight is not reducing even after hard exercise. My blood test shows T3 and T4 are normal, but TSH level is increased to 21. How can I reduce it?

High TSH with normal T3/T4 is equal to subclinical hypothyroidism. Weight gain is common. Start low dose levothyroxine under supervision. Recheck TSH in 6 weeks.

Dr. Shaik Suggests...

Take a Thyroid Profile (T3 T4 TSH) Test Test or Take a THYROID PEROXIDASE ANTIBODIES (ANTI MICROSOMAL ANTIBODIES) Test

I recently got my thyroid checked for the first time. My report shows T4 slightly higher than the reference range by 0.1. Should I consult a doctor for this?

Namaste sir, my name is Uma. I am using Thyiox 62.5 MCG since 6 months. Yesterday I did a thyroid test. Please see my report and suggest whether to use the same dose or make any changes?

Does only Graves disease cause heterogeneous echotexture in thyroid lobes? Both my thyroid lobes are showing heterogeneous echotexture with a cyst in the right lobe of the thyroid.
