“…These results reinforce the close association between obesity and depressive manifestations, wherein both conditions could be dependent on each other [73,74]. In this regard, Geerts et al reported that suboptimal weight loss after bariatric surgery was associated with impulsive eating, eating disorders, and depression [75]. Switzer et al reported a strong association between rebound weight gain and depressive manifestations after bariatric surgery [76].…”

Surgeons often focus on weight loss and improvement of obesity-related conditions as a primary outcome after bariatric surgery. However, the success of bariatric surgery also relies on the improvement of mental health status. Therefore, the current meta-analysis was carried out to reveal the prevalence of depressive symptoms and their subsequent impact on bariatric surgery outcomes. This study was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and the recommendation of Cochrane Collaboration. All clinical studies reporting the prevalence and/or the outcomes of depression after bariatric surgery were included in the current meta-analysis. This metaanalysis encompassed 33 articles, including a total of 101,223 patients. The prevalence of post-bariatric surgery depression was 15.

“…The ten articles reported the prevalence of post-bariatric depression. Data grouping revealed a prevalence rate of 15.3% (95% CI: 15.0-15.5%, p<0.001) [2,15,17,25,30,31,37,41,45,46].…”

“…There is a strong association between rebound weight gain and depressive manifestations, also associated with food adaptation, which is considered an important factor in long-term weight gain. However, according to the studies, there are not enough data for a definitive conclusion [15,16,42].…”

Depression is defined as a mood disorder, which presents as main characteristics changes in sleep, appetite, loss of interest in pleasurable activities, depressed mood, among others. Obesity is characterized as a chronic disease, of not yet fully clarified etiology, characterized by the accumulation of fat in adipose tissue, being able to negatively affect the metabolic system as a whole, compromising the health of the individual. The aim of this study was to conduct a systematic review on the prevalence of depressive disorder in the postoperative period of bariatric surgery. For this review, searches were performed in the following databases: Pub Med, SCIELO, LILACS, Elsevier and Embase. The following descriptors were used in Portuguese and English: depressive disorder, postoperative, bariatric surgery. We found 630 articles with the descriptors mentioned, of which after the selection process there were 46 articles for full reading, of which 10 met all inclusion criteria. Data collection was restricted to clinical research conducted with humans of both genders from 2010. The study concluded that there is a high demand of patients who underwent bariatric surgery with depression in the postoperative period.

Background: Despite the success of bariatric surgery for most patients, up to 30 % do not experience optimal weight loss outcomes. Reasons remain incompletely understood. Thyroid hormones, due to their role in energy expenditure, have received study. Yet research to date is inconclusive regarding the impact of standard thyroid markers (e.g., thyroid stimulating hormone, or TSH) on weight regulation after bariatric surgery. This prospective observational study investigates whether the early development of euthyroid sick syndrome (ESS) predicts reduced longer-term post-bariatric weight loss. ESS develops during periods of stress (e.g., critical illness, severe infection, famine) and is thought to serve a protective function by suppressing metabolism and conserving weight. Levels of metabolically active free triiodothyronine (FT3) drop, levels of non-catabolic reverse 3, 3, 5-triiodothyronine (rT3) rise, and TSH levels remain euthyroid. Reductions in the ratio of FT3 to rT3 significantly predict outcomes in critically ill patients with ESS yet have been unexamined in intentional weight loss among post-bariatric patients. Hence this hypothesis-generating preliminary study investigated whether early changes in the FT3:rT3 ratio predict weight changes at 1-2 years post-bariatric surgery. Methods: Twenty-three adult patients undergoing Roux-en-Y gastric bypass (n=12) or sleeve gastrectomy (n=11) were recruited from a bariatric surgery clinic. The TSH, FT4, FT3, rT3, and self-reported hypothyroid symptoms were collected 2-weeks pre-surgery and between 2 weeks to 3 months post-surgery. Body mass index was measured pre-surgery and 1-2 years post-surgery. Results: Reductions in the FT3:rT3 ratio from pre- to early post-surgery significantly predicted reduced weight loss at 1 (p= 0.03) and 2 years (p= 0.02) post-surgery. No other thyroid-related markers nor hypothyroid symptoms were predictive. Conclusions: Although replication with larger samples is needed (especially given sizeable study attrition), this small exploratory study provides provocative support that early changes in the FT3:rT3 ratio associated with ESS predict longer-term reductions in post-bariatric surgery weight loss. Clinical implications are discussed.
