The prevalence of obesity in the general population has increased markedly over the past few decades, accompanied by a parallel increase in the prevalence of obesity in pregnancy. The Centre for Maternal and Child Enquiries (CMACE) in the UK has developed national consensus standards of care for women with maternal obesity and these are available to clinicians and commissioners as CMACE/Royal College of Obstetricians and Gynaecologists (RCOG) guidance. Maternity services should develop a clinical care pathway for maternal obesity that takes into account locally agreed strategies for management. An appropriately trained health professional should provide dietary counselling to women who are obese. Maternity services will need to identify the prevalence of maternal obesity within the local maternity unit population to ensure adequate midwifery workforce planning. Maternity units should carry out regular audits of practice against locally agreed standards for women with obesity in pregnancy.
