Some degree of stimulation of the thyroid gland by human chorionic gonadotropin is common during early pregnancy.13 When serum chorionic gonadotropin concentrations are abnormally high — for example, in women with molar pregnancies — overt hyperthyroidism may ensue. The pathophysiologic mechanism is believed to be promiscuous stimulation of the thyrotropin receptor by the excess chorionic gonadotropin.4,5 The explanation for this stimulation is the close structural relations between chorionic gonadotropin and thyrotropin and between their receptors.6
Hyperemesis gravidarum is characterized by excessive vomiting in early pregnancy, leading to the loss of 5 percent or more of body weight.4 It . . .
