19,20 Benefit of thyroxine treatment has been demonstrated for thyroid peroxidase antibody (TPOab) positive women with SCH, but there is little prospective data on intervention in TPOab negative women. Thyroxine is used for treating overt hypothyroidism and is recommended in antibody positive subclinical hypothyroidism.
Having low thyroid hormone levels may even interfere with becoming pregnant or be a cause of miscarriage.

Women with overt hypothyroidism taking LT4 pre-pregnancy may need an increase in LT4 by 25–50%, depending on the aetiology of hypothyroidism and the pre-pregnancy TSH level [ Lazarus et al, 2014 ]. Thyroid hormone replacement is used to treat the mother. The ATA guidelines note that one option is to increase the daily dose of LT4 by approximately 25–30% as soon as pregnancy is suspected. hÞb```c``ªe`a`Ö{ÅÀÏ ü@1V æ¸ÀÀXs&ÌòH×EÕ;9Á,£££ALÕ eÙØö½ÒÂ@, Hypothyroidism is a condition that is caused by an underactive thyroid gland.

The goal of treating hypothyroidism in a pregnant woman is adequate replacement of thyroid hormone. Consequently, most women on levothyroxine therapy before pregnancy require an increase in dose when pregnant to maintain euthyroidism. A pregnant woman with symptoms of hypothyroidism, a history of hypothyroidism, or with other endocrine system conditions should be screened.

Thioamide drugs (ie, ATDs) are the first-line treatment in pregnancy. Levothyroxine requirements frequently increase during pregnancy, usually by 25 to 50 percent. It can go undetected if symptoms are mild. Hypothyroidism is often suspected when TSH levels are above normal and T4 levels are below normal. Treatment (follow TSH every 4 to 6 weeks and titrate to lower reference limit) Levothyroxine: 1 to 2 micrograms/kg daily | Typically 100 micrograms daily; Avoid T3 compounds (fetal CNS development dependent on maternal T4) Pre-pregnancy diagnosis: Medication requirement will likely increase 25% ; KEY POINTS: Hyperemesis Gravidarum And Hyperthyroidism Having low thyroid hormone levels can also cause problems with becoming pregnant.
