Obesity (defined as a BMI of 30 or more), especially extreme obesity, is known to decrease the likelihood that a woman can become pregnant. In addition, when obese women do become pregnant, they are more likely to develop gestational diabetes, and have an increased risk of large babies, early delivery, and stillbirths, and their infants are at increased risk of congenital malformations.
