The National Institute for Health and Care Excellence provides detailed guidelines for maternity service staff in relation to body mass index (BMI) and managing weight during pregnancy.

This includes the Antenatal Care Guidance which specifies that women should be offered measurement of height and weight, including a calculation of BMI, at their antenatal booking appointment. This should also include an explanation of BMI’s relevance to pregnancy, as well as associated risks and available support. This guidance is available at the following link:

In addition, the Overweight and Obesity Management Guidance specifies that for women with a BMI of 40 kilogram per meter squared of height or above, this discussion should include the option of referral to a specialist obesity service or specialist practitioner for tailored advice and support during pregnancy.
