My wife is currently taking Thyronorm 75 mcg. Before conceiving, her TSH level was 3. Now, at 5 weeks pregnant, her latest TSH level is 4.73. The reference range for TSH in the first trimester is below 4.5. Could you please advise if this level is a concern and if any changes to her medication or treatment are needed?

A TSH level of 4.73 in the first trimester is slightly high. It should ideally be under 2.5 to 4.0. The doctor may increase thyronorm dosage slightly. Regular monitoring of Thyroid levels and consultation of a gynaecologist is advised.
