Abstract
Aims Obesity is an increasing problem, even in young women of reproductive age. Obesity has a negative impact on conception, the course of pregnancy, and neonatal outcomes. Caring for obese pregnant women is becoming an increasingly important aspect of standard prenatal care. This guideline aims to improve the care offered to obese pregnant women. Methods This S3-guideline was compiled following a systemic search for evidence and a structured process to achieve consensus. Recommendations Evidence-based recommendations for the care of obese pregnant women were developed, which cover such as areas as preconception counselling, identification of risks, special aspects of prenatal care and prenatal diagnostic procedures, intrapartum management, and long-term effects on mother and child.
