This study evaluates the association between weight loss following laparoscopic Roux-en-Y gastric bypass (LRYGB) and self-perceived QoL improvement. Medical records of patients treated between January 2017 and December 2019, with at least 3 years follow-up, are compared across %TWL, age, and time since surgery using SF-36. Among 95 individuals, physical functioning scored best and pain worst, with specific QoL domains improving by greater %TWL, older age, and longer postoperative duration.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/weight-loss-and-self-perceived-quality-of-life-following-laparoscopic-roux-en-y-gastric-bypass-is-it-important/461718/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/weight-loss-and-self-perceived-quality-of-life-following-laparoscopic-roux-en-y-gastric-bypass-is-it-important/461718.png","ImageObject",300,407,{"name":42,"@type":43},"pixelkiddo","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-31","2026-09-30",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the main focus of this study after laparoscopic Roux-en-Y gastric bypass?","Question",{"text":63,"@type":64},"The study focuses on how the amount of weight loss after LRYGB relates to self-perceived quality of life improvement, assessed using SF-36.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How were participants and follow-up handled in the analysis?",{"text":68,"@type":64},"Patients who underwent LRYGB between January 2017 and December 2019 were included, requiring a minimum follow-up of 3 years.

The amount ofWL is generally directly and proportionally associated with the improvement in quality of life (QoL), as the greater the former, the greater the perception of well-being. However, improvements in QoL may also not belinearly related to the amount of weight lost, as nonsignificant reductions in body weight may already be sufficient to increase QoL in physiological, psychological, social, and economic aspects. Furthermore, QoL seems to be one of the main targets of patients seeking bariatric procedures, which is not always properly valued.  \nPERSPECTIVES  \nIn the present study, we demonstrate that the amount of weight lost provided by laparoscopic Roux-en-Y gastric bypass can have a direct relationship with significant positive impacts on health-related selfperceived QoL, both physical and emotional. Moreover, these effects appear to be sustained in the long term, especially in older individuals.  \n [instagram.com/revistaabcd/](instagram.com/revistaabcd/)  \n[https://x.com/revista_abcd](https://x.com/revista_abcd)  \n [facebook.com/Revista-ABCD-109","cbCainlpWABYwzEt","https://ap.wps.com/l/cbCainlpWABYwzEt","pdf",2271570,"English","# Article Highlights\n## Central Message\n## Perspectives\n## Abstract\n## Visual Abstract","[{\"question\":\"What is the main focus of this study after laparoscopic Roux-en-Y gastric bypass?\",\"answer\":\"The study focuses on how the amount of weight loss after LRYGB relates to self-perceived quality of life improvement, assessed using SF-36.\"},{\"question\":\"How were participants and follow-up handled in the analysis?\",\"answer\":\"Patients who underwent LRYGB between January 2017 and December 2019 were included, requiring a minimum follow-up of 3 years.
