  • Maternal age (being over the age of 35)
  • Pregnancy and smoking

Complete placenta:

The placenta thoroughly covers the cervical opening in this case.The placenta totally impedes the cervical opening, making vaginal conveyance impossible.For instances of full placenta previa, a cesarean segment (C-area) is normally the suggested method of birth.

Partial placenta:

The placenta somewhat covers yet doesn’t totally limit the cervix in fractional placenta previa.This means that the child can go through some space during birthing, yet it is as yet a high-risk circumstance.The decision between vaginal conveyance and C still up in the air by the degree of inclusion and different models.

Marginal placenta:

This condition happens when the placenta’s edge comes to or is very near the cervical opening however doesn’t cover it.This sort of placenta previa is less extreme than complete or fractional previa, and it could be related with a lower chance of pregnancy and work drain issues.Vaginal conveyance might be conceivable in certain examples, yet it should be painstakingly checked.
