CONCLUSIONS: This is the first study to suggest that crucial phosphate supplementation contributes to refeeding oedema in patients with EDs. Future studies should seek to better understand the relationship between phosphate supplementation and weight trends in order to optimise clinical management.

CONCLUSIONS: Higher peak postprandial concentrations of anorexigenic PYY in AN (compared to HC) may facilitate dietary restriction and contribute to maintenance of lower weight. Lack of CCK suppression in AN is maladaptive in the context of undernutrition. Despite continued restriction, ghrelin is adaptively higher in AN overall and may not be differentiated by weight status.

CONCLUSIONS: Even though randomized controlled trials (RCTs) have been performed to test treatments for obesity in the armed forces, RCTs for the treatment of EDs, body dysmorphic disorder, muscle dysmorphia, and RED-S syndrome are lacking in the military context.

CONCLUSIONS: ARFID and selective eating patterns are rare but notable occurrences after pediatric LT, but they may also be underreported given the novelty of ARFID and the prevalence of gastrointestinal symptoms following transplant. Our case adds to the limited literature on ARFID in children following major surgical procedures and highlights the importance of interdisciplinary care and the importance of nutritional management in pediatric patients prior to and post LT.
