A cesarean section (also called a C-section) is a common surgery that is performed to remove the baby from the uterus. About one million cesarean sections are performed each year in the United States, making them the most common major surgery done today. During the procedure, an incision is made in the abdomen and uterus, and then the baby is removed from the opening. There are possible complications associated with cesarean section, as there are with any surgery; however, it is typically a safe procedure. Some of these possible complications include urinary tract infections (UTI), minor bleeding, allergic skin reactions, and an abnormal or painful scar. Women who are overweight or who use alcohol, tobacco products, or other drugs (such as cocaine) are at a greater risk for complications. A woman's age and any other medical problems she may have can also be factors in whether she has complications. Among the complications rarely seen in babies delivered through cesarean section are scratches or cuts, fractures of the skull or long bones, and serious brain or nerve damage.
