AbstractWith a rising worldwide incidence of obesity, particularly in the young, bariatric surgery offers an effective method of meaningful and sustained weight loss. At present, most bariatric procedures are carried out in women and increasingly in younger age groups. In line with the fertility benefits associated with weight loss, pregnancy after bariatric surgery is now a very common scenario. Although there is limited evidence to support optimal care in this group, most women appear to have good pregnancy outcomes, with reduced rates of pre-eclampsia and gestational diabetes (GDM). However, rates of stillbirth and small-for-gestational-age (SGA) babies are increased, suggesting that screening and supplementation of micronutrients is likely to be very important in this cohort. The risks and benefits that bariatric surgery may pose to pregnancy outcomes, both maternal and fetal, are largely dependent upon the degree of weight loss, weight stability upon entering pregnancy, surgical complications and the time interval between bariatric surgery and pregnancy. Ideally, preconception care would be more widely available, helping to assess and address micronutrient deficiencies and support preparation for pregnancy.Copyright © 2024.
