Background and aims: An excessive weight loss (EWL) of >10% after birth is associated with serious health outcomes. The aim of this study was to determine factors that can reduce weight loss in full-term, exclusively breastfed infants after birth. Methods: This is a retrospective, observational, single-center study. We included 642 healthy, full-term, exclusively breastfed neonates born in 2019 in a baby-friendly hospital, and their healthy mothers. The exclusion criteria were as follows: supplementation with formula, multiple pregnancies, and neonates or mothers with health issues. Results: The mean percentage of neonatal weight loss after 24 h of life was 5.13%, and that after 48 h was 6.34%. Neonates delivered via a caesarean section lost more weight after 24 and 48 h of life than those delivered via vaginal delivery (p 0.05). Conclusions: Neonates born via a CS tend to lose more weight after 24 and 48 h of life. Immediate SSC and breastfeeding in the first hour after delivery may decrease the excessive weight loss.
