Pregnancy outcome among individuals with obesity and low gestational weight gain (May 2024)
For individuals with obesity, increasing evidence suggests that gestational weight gain (GWG) below standard recommendations (5 kg) is safe and may result in a more favorable pregnancy outcome. In an observational study including over 11,000 pregnancies with class I obesity, 3000 with class II obesity, and 900 with class III obesity, GWG below 5 kg was not associated with an increased risk of the composite adverse outcome in those with class I or II obesity and was associated with a 20 percent risk reduction in those with class III obesity
