An example is hyperthyroidism,
which occurs in approximately 1 in
500 pregnancies and is one of the
most common endocrine disorders
of pregnancy, second only to diabetes.3
Graves disease accounts for more
than 85% of all cases of hyperthyroidism.
4 Maternal and neonatal
morbidity is significantly more common
in women whose hyperthyroid
state is not medically controlled.
Thyroid storm is especially common
in women who receive limited or no
prenatal care and have medical or
obstetric complications.2 Pregnant
women with hyperthyroidism require
careful management to prevent complications
and adverse outcomes for
both mother and infant.
