Excessive weight gain in pregnant women has become one of the important factors that harm mother′s health and cause adverse pregnancy outcomes. Excessive weight gain during pregnancy can increase the pregnancy complications and adverse pregnancy outcomes, such as macrosomia, which increase the rate of cesarean section.
