Variables Associated with Short-Term Weight Loss in a Cohort of Patients with Morbid Obesity According to Age and Three Types of Bariatric Surgery. J Clin Med. 2020 Nov 2;9(11):35372077-0383https://hdl.handle.net/10668/27088Background The percentage of excess weight lost (%EWL) after bariatric surgery (BS) shows great discrepancies from one individual to another. Objective To evaluate the %EWL one year after BS and to determine the existence of baseline biomarkers associated with weight loss. Methods We studied 329 patients with morbid obesity undergoing three types of BS (biliopancreatic diversion (BPD), Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG)), depending on the %EWL one year after surgery: good responders (GR) (%EWL≥50%) and non-responders (NR) (%EWL Results: The GR presented a higher percentage of change in anthropometric and biochemical variables compared to the NR group, even within each type of BS. There was a greater percentage of GR among those who underwent RYGB. The patients who underwent SG showed the lowest decrease in biochemical variables, both in GR and NR. Within the GR group, those with a lower age showed greater improvement compared to the other age groups. A %EWL ≥50% was negatively associated with age and atherogenic index of plasma (AIP), and positively with the type of BS (RYGB). Conclusions: The GR group was associated with lower age and AIP and undergoing RYGB. Additionally, those patients who underwent SG showed a lower metabolic improvement.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Bariatric surgeryExcess weight lossMorbid obesityGastric BypassObesity, MorbidBiliopancreatic DiversionBariatric SurgeryWeight LossGastrectomyresearch article33147793open accessPérdida de pesoPlasmaGrupos de edadObesidad mórbidaCirugía bariátricaDerivación gástrica10.3390/jcm9113537PMC7692348https://www.mdpi.com/2077-0383/9/11/3537/pdf?version=1604480342https://pmc.ncbi.nlm.nih.gov/articles/PMC7692348/pdf
