Overweight and obesity have several impacts on women’s health. The common health consequences are polycystic ovary syndrome, fatty liver, gestational diabetes mellitus, and  hypertensive disorders in pregnancy. These conditions affect pregnancy and childbirth outcomes, including preterm labor, induction of labor, cesarean section, postpartum hemorrhage, macrosomia, low-birth weight infant, congenital anomalies, and intrauterine fetal death. Nursing care aims at preventing overweight and obesity, reducing their impacts on women health and pregnancy outcomes.
