Our data demonstrate a marked improvement in sleep efficiency and sleep fragmentation with surgical weight loss. Given the emerging evidence that surgical weight loss results in resolution of obesity-associated psychosocial, metabolic, and cardiovascular morbidity, these results suggest that correction of sleep fragmentation could be an important but as yet underappreciated factor influencing changes in these other major comorbidities of obesity.
Obese children have a high frequency of enlargement of the lingual tonsils with a significantly higher prevalence in those with previous tonsillectomy. Enlarged lingual tonsils may play a role in the pathogenesis of obstructive sleep apnea in obese children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
