Hi,
Welcome to the forum. I am really glad to help you out. Increased impedance (resistance) to flow in the uterine arteries in both high-risk and low-risk pregnancies is associated with increased risk of development of pre-eclampsia and intrauterine growth restriction.
Women with normal impedance (resistance) to flow in the uterine arteries constitute a group that have a low risk of developing obstetric complications related to uteroplacental insufficiency. Increased impedance (resistance) to flow in the uterine arteries in pregnancy attending for routine antenatal care identifies about 50% of those that subsequently develop pre-eclampsia. Hence, it makes sense to get your blood pressure measured regularly and also get your urine analysis done. Please do consult an obstetrician for the same. I sincerely hope that helps. Take care.
