A British study researched the link between medication given to women to prevent hemorrhaging after childbirth and breastfeeding rates for those women.

The drug oxytocin is commonly given to women after childbirth to prevent severe blood loss (>500 mL in 24 hrs.) known as postpartum hemorrhage (PPH). This can lead to fainting or severe anemia.

After a vaginal birth, the mother’s body must expel the placenta which creates rapid blood loss. The doctor or midwife will apply firm pressure on the fundus, or top of the uterus. This promotes postpartum contractions of the uterus so the placenta will be expelled and blood vessels will constrict to prevent severe blood loss.

Many doctors routinely use oxytocin even if the woman is not at risk for PPH. Women who have had a poor pregnancy diet,
