My thyroid was within normal range but I am pregnant and my doctor has told it to reduce it to below 3.now I am taking 100 mg thyronorm medicine. Is it considered hyperthyroidism or hypothyroidism. Will my medication stop after pregnancy.

lybrate-user ji, Thanks for the query. During pregnancy and even before conception, TSH has to be maintained at the lower end of the nor, mal. During pregnancy recommended levels are: 1st Trimester: 0.1 to 2.5 mU/L, 2nd Trimester: 0.2 to 3.0 mU/L, 3rd Trimester: 0.3 to 3.0 mU/L. Ideally it is good to maintain TSH around 2 mU/L. This condition is known as hypothyroidism. By maintaining TSH <2 mU/L, it helps better fetal growth, as well as results in desired out come of the pregnancy. You should check TSH once every 4 weeks during that period, to ensure proper levels are maintained. If you have any doubts please do come back. Thanks.
