Does this even happen?
I ask because when my mom was pregnant with me, she went almost a week past her edd, and was told that I had lost weight in utero, I think because of high blood pressure, and i was born at 5 lbs 11 oz by c-section (i was breech).
I was wondering because I thought doctors could not tell how much a baby weighs in the womb, although I guess they could feel if the baby was smaller?
with high blood pressure, there is concern that the placenta might not be optimal to supply baby with all of its needs. However, even in a woman that has high bp, this is not always the case.
through ultrasound measurements, providers can tell if baby's growth has slowed, or has become assymetrical, which could indicate a restriction of growth due to placental insufficiency.
weight estimates via u/s are just that - estimates. same thing with gestational age estimates. many times they are off by as much as 2 pounds / 3 weeks, so it's more accurate to look at a variety of things: amniotic fluid volume, head circumference, abdominal circumference, etc.
