Another name for this is gestational trophoblastic disease. The abnormal placental tissue grows and often causes enlargement of the uterus that is more rapid than usual. It is more common in the early and late years of childbearing. Symptoms are uterine bleeding, rapid enlargement of the uterus, absence of fetal heart activity, nausea and vomiting. Ultrasound easily diagnoses a molar pregnancy.
Continued pregnancy puts the mother's health at grave risk.
Many doctors recommend postponing pregnancy for at least 1 year after a molar pregnancy.
