What condition is characterized by the placenta detaching from the uterus prematurely?

The condition characterized by the placenta detaching from the uterus prematurely is known as abruptio placenta. This occurs when the placenta separates from the uterine wall before the delivery of the baby. It can result in bleeding and may compromise the oxygen supply to the fetus, potentially leading to severe complications for both the mother and the baby.

In the context of abruptio placenta, the separation can be complete or partial and the severity of symptoms can vary widely. Common indicators include sudden abdominal pain, vaginal bleeding, or tenderness in the abdomen, and a rapid onset of contractions.

In contrast, placenta previa is a condition where the placenta is located low in the uterus, covering or being close to the cervix, which can cause bleeding during pregnancy but is not related to premature detachment of the placenta. Preterm labor refers to the onset of labor before 37 weeks of gestation, and ectopic pregnancy involves the implantation of the fertilized egg outside of the uterus, usually in one of the fallopian tubes, neither of which involves placental detachment.
