placenta previa

Researchers from the Obstetrics and Gynecology Unit at Queen Charlottes and Chelsea Hospital in London recently published a study in the journal Human Reproduction on the effect of C-section scarring on future implantation.

Researchers and authors from the Department of Obstetrics and Gynecology with Washington University report women who experience vaginal bleeding early in a twin pregnancy may be at increased risk of pre

Placenta previa is a potentially life-threatening condition during and after pregnancy when the placenta covers the cervix .

"In an interview with Us Weekly magazine, the 39-year-old mother of four revealed just how risky her fourth pregnancy really was."

During a normal pregnancy, your placenta will start low and slowly make its way up towards a richer blood supply. The placenta is the organ that connects your growing baby with your blood supply for the transfer of nutrients and waste removal. When your placenta moves up, it also makes way for your baby to leave the birth canal when it’s time for labor. However, some women’s placentas never make their way up, and this condition is called placenta previa.

Placenta previa, a medical condition characterized by a low attachment of the placenta over the cervical opening, can increase the risk of hysterectomy and excessive blood loss during C-section delivery.

The placenta is the organ that supplies all the oxygen and nutrients the growing fetus needs, it produces important hormones,  but it also removes waste from the fetus. The fetus is attached to the placenta via the umbilical cord.

Vaginal bleeding in pregnancy is far more common during the first trimester of pregnancy than many women believe. Bleeding in the second and third trimesters of pregnancy however are of far greater concern.

What is a placenta previa?
A placenta previa is a placenta that is implanted at or close to the internal os (mouth) of the cervix.
 Placenta previa happens in about 1 in 200 pregnancies, though the incidence has increased over the last years because certain risk factors such as prior cesarean sections have increased.

A placenta creta, accreta, increta, or percreta is a placenta that grows during pregnancy into or through the uterus. Having this condition is life-threatening and requires expert surgical and medical care.

There are times when a pregnant women will not be able to give birth to a baby vaginally. When vaginal births are too risky or the birth must happen very quickly, a cesarean section, or c-section, is chosen by the obstetrician for the safety of both baby and mom.

About 80% of cesarean sections are done for one of the following four reasons:
