As explained by the Mayo Clinic, a cesarean-section is a birthing method where the baby is delivered via an incision into the abdomen and uterus. It's often performed because of complications associated with vaginal delivery, or when a woman is giving birth to multiples. While this procedure is quite common there are still quite a few risks involved, including the following.
Deep vein thrombosis is a condition where a blood clot forms deep in the veins, usually within the legs or pelvis. This blood clot may eventually travel to the lungs, where it can cause a potentially fatal pulmonary embolism. C-sections actually increase the risk of the mother forming a blood clot, which is why it's crucial that your doctor goes over your medical history when talking about your birthing plan.
C-section complications may also affect the baby. Characterized by abnormal breathing and rapid breaths, transient tachypnea is a serious complication that can present in the days immediately following the birth. Fluid within a baby's lungs is absorbed into the organ as the due date draws closer, but it can also be expelled during a vaginal delivery. Fluid is sometimes left in the lungs after a c-section, which causes respiratory problems.
Just like all other surgical procedures, a c-section can cause unintentional injury to the baby and the mother. While rare, babies are sometimes cut by the scalpel used to gain access to the womb. This can lead to serious bleeding, while also greatly increasing the risk of infection. Mothers may also experience injuries during c-section surgeries, including damage to other organs, such as the bladder.
