Extremely obese women might not need to gain weight during pregnancy, recent research has suggested.
Presented at the Society for Maternal-Foetal Medicine's annual meeting, the study found that these women did not suffer any ill effects if they gained less than the recommended amount of weight during their second and third trimesters of pregnancy.
Eva Pressman, director of maternal foetal medicine at the University of Rochester Medical Center, commented: "The study suggests that even the recommended amounts of weight gain might be more than is needed for the most obese women."
Their babies also did not demonstrate any negative issues, while those of obese and non-obese women who did not gain the recommended amount of weight saw undesirable outcomes.
These included a higher chance of delivering a baby that is small for its gestational age.
Meanwhile, the lead author of the report, Danielle Durie from the Department of Obstetrics and Gynaecology at the university's medical centre, added that there may be "even more tailored guidelines" in the future to guide women with different levels of obesity through pregnancy.
