If TSH is found to be on the high side in the early pregnancy, you should go to the endocrine department in time, and the doctor will give a treatment plan according to the high level of THS and the specific condition. If you are pregnant within eight weeks, you can supplement levothyroxine sodium. If the TSH is greater than ten, you need to supplement thyroid hormone. If the TSH is lower than ten, higher than the upper limit of the reference value, and the TPO antibody is positive, you should supplement thyroid hormone, TSH is a hormone secreted by the adenohypophysis, which secretes thyroid stimulating hormone. On the one hand, TSH is promoted by TSH releasing hormone secreted by the hypothalamus, and on the other hand, it is inhibited by thyroid hormone feedback.
