What are the warning signs of severe bleeding after cesarean section in pregnant women?

In general, cesarean section is medically referred to as cesarean delivery. Warning signs of severe hemorrhage after cesarean delivery in pregnant women may include increased vaginal bleeding, rapid heartbeat, decreased blood pressure, and shock. The details are as follows:

1. Increased vaginal bleeding

After cesarean delivery, it is normal for a woman to experience lochia discharged from the vagina, resulting in postpartum vaginal bleeding. However, if a woman in the recovery period experiences excessive and persistent vaginal bleeding, she should immediately call a doctor for evaluation and hemostatic treatment.

2. Rapid heartbeat and low blood pressure

Significant blood loss following cesarean delivery can cause rapid changes in heart rate and blood pressure. When postpartum hemorrhage occurs, the mother's heartbeat accelerates. If bleeding continues along with decreasing blood pressure, this indicates a potential massive hemorrhage, and close monitoring of the mother’s heart rate is essential.

3. Shock

If vaginal bleeding is excessive or prolonged, the circulating blood volume in the mother's body may drop significantly, leading to a series of symptoms of hypovolemic shock, such as dizziness, pale skin, and sweating. At this point, the woman is in a very weak and dangerous condition. Family members should closely monitor her status and notify medical staff immediately upon noticing any abnormalities.

Besides the three conditions above, other warning signs may include elevated uterine fundus and hematometra (accumulation of blood in the uterine cavity). To prevent massive hemorrhage during cesarean delivery, pregnant women should maintain good nutrition and follow a balanced diet before and after childbirth, while doctors should thoroughly evaluate the patient’s health condition prior to surgery.
