I am 29 years old and 15 weeks pregnant now. I am using 137.5 mg Eltroxin tablet from one month. Today I got results of TSH 0.3, Total T4 19.9 and Total T3 1.96. Why does my total T4 level show high? Is there any problem for my pregnancy and my baby?

In pregnancy, thyroid hormone levels, especially total T4, can be higher than usual due to hormonal changes. A slightly high T4 alone is not usually harmful, especially if TSH is within target. Your TSH is on the lower side, which may need monitoring. Continue medication as advised and follow up regularly with your doctor.

Why are both my TSH and T4 levels high? I understand that a high TSH usually means hypothyroidism, so why is my T4 also high? Is this a serious problem? I am really worried. Please check my report and help me understand.

Hello, I have been taking Methimez 10 mg twice a day for hyperthyroidism for the past 5 months. I also have a thyroid nodule. Last week, my blood report showed a high increase in TSH level. What is the solution to bring my TSH back to normal?
