Thyroid Disorders in Pregnancy
Maternal hypothyroidism
Women with mild to moderate Hypothyroidism frequently have normal menstrual cycles and can become pregnant. During pregnancy, the usual dose of L-thyroxine is continued. As pregnancy progresses, minor dose adjustments may be necessary, ideally based on TSH measurement after several weeks. If hypothyroidism is first diagnosed during pregnancy, L-thyroxine is started; dosing is based on weight. Usually, pregnant women require a higher dose than nonpregnant women.
