Your weight in pregnancy

Weight gain is expected during a pregnancy, and you may have questions about how it will impact on your body. Some clients also begin their pregnancy with a high or low Body Mass Index (BMI), and your midwife can discuss any questions or concerns you might have about your weight during pregnancy. The following guidelines include evidence-based recommendations and information for clients with high or low BMIs.
