Honor Society of Nursing (STTI) answeredPlacenta previa cannot be prevented. You cannot control where your placenta positions itself or where it may shift to. The condition and shape of your uterus may be to blame or the shape of the placenta itself, but these are all factors that you have no power over. You may be able to prevent some bleeding, though, by avoiding sexual intercourse and too much activity (through bed rest).
Placenta previa is not preventable. Most of the risk factors involve situations that change the integrity of the uterine lining and over which the woman has no control. The one known risk factor for placenta previa which the woman can modify is smoking.
