Q: Dr. please, what is the cause of placenta previa ? Can it be cured or prevented ?

A: Placenta previa (PP) is a condition associated with the placenta…you already figured that out, right? 😀 The placenta is created during pregnancy and is attached to the wall of the uterus (the womb) by blood vessels. It is through the placenta that the baby receives vital nutrients and oxygen and also through this that it excretes waste products. The baby is connected to the placenta through the umbilical cord. So this is a pretty important organ in the general scheme of things. The baby’s and mother’s blood do not mix in the placenta usually, though. The baby’s blood flows on one side and the mother’s on the other side.

The placenta usually implants at the top part of the uterus or the side, but in placenta previa the placenta attaches low…
