Bleeding after childbirth (postpartum bleeding) is an excessive loss of blood from the uterus or the vagina within the first 24 hours after childbirth. This usually occurs because the weak contractions of the uterus are not enough to stop the bleeding which starts when placenta detaches from the uterus. Insufficient contraction may be a consequence of exhaustion due to long-term childbirth, as well as the previous weakening of the uterus muscle, which occurs when the uterus is excessively stretched due to double pregnancy or multiple pregnancies.
Bleeding can occur if the parts of the placenta stay in the uterus, thus preventing stronger contractions. It can also occur if there was a vaginal tearing during childbirth. Bleeding from the uterus can be stopped with drugs that stimulate the uterine contractions. The ophthalmologist manually removes parts of the placenta if they remain in the uterus. If a bleeding occurs due to vaginal tearing, the tear is stitched under the local anesthesia.
