Abstract

Postpartum thyroid dysfunction occurs in 5-10% of women within one year after delivery. Women with hypothyroidism antedating pregnancy are at high risk for postpartum thyroiditis and should be closely monitored during the first year post-partum. Here, we report a case of recurrent hyperthyroidism between two episodes of postpartum thyroiditis in a woman diagnosed with subclinical hypothyroidism prior to pregnancy. It is of particular interest that spontaneously remitting hyperthyroidism as a sequela of postpartum thyroiditis can occur.
