For a mom, an elected C-section can raise the chance of death by at least 60 percent, and in some circumstances as much as 700 percent, several studies have reported. And it increases a woman's risk of life-threatening complications during childbirth, such as bleeding, uterine rupture, hysterectomy and cardiac arrest by about fivefold. This risk rises even further in subsequent deliveries.
For babies, C-sections raise the chance of obesity and autoimmune diseases later in life. When the procedure occurs before 39 weeks, an early birth increases the infant's risk of respiratory problems.
