The aim of our systematic review is to evaluate the relationship between AT and postoperative weight gain in children to guide clinicians in optimizing surgical outcomes. Methods: A systematic search was conducted following the PRISMA guidelines in PubMed, MEDLINE, and Web of Science databases. Studies evaluating weight, BMI, and growth parameters before and after AT were included. Data were collaboratively extracted, including patient demographics, baseline weight status, comorbidities, and long-term outcomes. Results: Underweight children (less than the 3rd percentile on the growth chart) who underwent AT often experienced \u201ccatch-up growth\u201d in weight, while obese children (above the 95th percentile on the growth chart) had postoperative weight gain that exacerbated pre-existing obesity. These outcomes were affected by factors such as baseline weight, age, and comorbid conditions. Conclusions: AT can improve the quality of life in underweight children, while overweight or obese children need careful monitoring and nutrition counseling postoperatively to mitigate excessive weight gain. More randomized trials are needed to better understand the metabolic and growth implications of AT and to refine clinical guidelines.<\/jats:p>","DOI":"10.3390\/children12030270","type":"journal-article","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T07:46:57Z","timestamp":1740383217000},"page":"270","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Impact of Adenotonsillectomy on Weight Gain in Children: A Systematic Review"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8333-1777","authenticated-orcid":false,"given":"Omar Ibrahim","family":"Alanazi","sequence":"first","affiliation":[{"name":"College of Medicine, King Saud University, Riyadh 11426, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz","family":"Alsharif","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Vision College, Jeddah 23643, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-5202-9173","authenticated-orcid":false,"given":"Arwa","family":"Alsharif","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanan Ismail","family":"Wasaya","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faten","family":"Aljifri","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9609-4931","authenticated-orcid":false,"given":"Atheer","family":"Mohammed","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reem","family":"Halawani","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdalhadi Mahmood","family":"Halawani","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Batterjee Medical College, Jeddah 21442, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baraa","family":"Awad","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head & Neck Surgery, College of Medicine, King Saud bin Abdulaziz University for Health Sciences, Jeddah 21423, Saudi Arabia"},{"name":"King Abdullah International Medical Research Center, Ministry of the National Guard\u2014Health Affairs, Jeddah 22384, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Halawani","sequence":"additional","affiliation":[{"name":"Pediatric ENT, King Abdullah Specialized Children\u2019s Hospital (KASCH), Riyadh 11426, Saudi Arabia"},{"name":"Ministry of National Guard Health Affairs (MNGHA), Riyadh 11426, Saudi Arabia"},{"name":"King Abdullah International Medical Research Center, Riyadh 11426, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"407","DOI":"10.1016\/j.otc.2024.02.025","article-title":"Adenotonsillectomy for Obstructive Sleep Apnea in Children","volume":"57","author":"Jaensch","year":"2024","journal-title":"Otolaryngol.
