Bariatric surgery is an effective treatment option for obesity, but its effects on reproductive hormones are not well understood. This study aimed to investigate the impact of bariatric surgery on estrogen and progesterone levels in women with obesity. This was a prospective study that included 87 women with obesity who underwent bariatric surgery and 87 control women with obesity who did not. Blood samples were collected at baseline and at 3-month and 6-month follow-up periods to measure reproductive hormones and Adiponectin as well as medical history and physical examination for endometriosis and polycystic ovary syndrome (PCOS). The study found that sleeve gastrectomy significantly increased follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in the bariatric surgery group compared to the control group at 3 and 6-month follow-up. There was no significant difference in the mean levels of estrogen and progesterone between the two groups at the 3-month follow-up period. Bariatric surgery leads to significant weight loss in women with obesity, but it does not seem to have a significant impact on estrogen and progesterone levels in the short-term. Future studies with longer follow-up periods are needed to investigate the long-term effects of bariatric surgery on reproductive hormones.

Purpose: This study aimed to explore the weight loss experience of highly obese young people who underwent bariatric surgery. Methods: Data were collected, from October 2021 to April 2022, through individual in-depth interviews with eight highly obese young adults who underwent bariatric surgery and analyzed using Colaizzi's phenomenological method. Results: The following four theme clusters were extracted. First, 'The unbearable sorrow of obese people' explains the process of choosing bariatric surgery after fluctuations and frustration despite countless repeated weight loss attempts. Second, 'The impact aftermath of bariatric surgery' revealed participants struggling in the face of unexpected changes due to bariatric surgery. Third, 'Efforts to rebuild a healthy myself' demonstrated the struggle to regain health by using the surrounding support system to overcome the difficulties of this surgical procedure. Lastly, 'Facing life by getting rid of the yoke of obesity' displayed the experiences of the participants who felt ambivalent about their changed appearance, but coping positively with the new life. Conclusion: This study provides an in-depth understanding of the weight loss experiences of highly obese adolescents who underwent bariatric surgery and presents a new perspective on clinical practice. The results of this study are expected to be useful in developing and applying systematic and customized nursing interventions before and after bariatric surgery.

Objectives: The purpose of this study was to investigate the prevalence of eating disorder high risk group and eating disorder among whom visit bariatric clinic for diet and its relationship with sex, ages and body measurement. Methods: 742 subjects who visit our clinic both at Seocho and Bundang from January to October in 2004 were surveyed by using EAT-26 to assess their eating attitude. Results: The prevalence of eating disorder high risk group was 17.9% and that of eating disorder was 3.2%. Mean score of EAT-26 was higher in females$(13.22{\pm}8.52)$ than males$(8.95{\pm}5.44)$ and was significantly higher in twenties than the thirties in females(p<0.05). Mean weight, BMI and % body fat were significantly lower in eating disorder high risk group than normal group(p<0.05). Conclusions: Eating disorder symptomatology was highly prevalent among whom visit bariatric clinic for diet.

Obstructive sleep apnea syndrome (OSAS) has negative effects on health, including increased mortality, risk of cardiovascular disease, and neurocognitive difficulties. OSAS is common in obese patients and obesity is an important risk factor of OSAS. A 41-year-old female OSAS patient with severe obesity (body mass index [BMI] ${\geq}35$) who failed dietary weight loss underwent bariatric surgery. After surgery, there were improvements in BMI (from 36.9 to $31.7kg/m^2$) and polysomnographic data, including the apnea-hypopnea index (from 25.1 to 11.2 events/hr) and minimum SaO2 (from 69 to 82%). This case demonstrates that bariatric surgery may be an effective therapeutic option to reduce sleep-disordered breathing in severely obese patients with moderate OSAS. Bariatric surgery as a treatment option for OSAS should be considered in OSAS patients with severe obesity who failed dietary weight loss.

Background Bariatric surgeries performed in the USA has increased twelve-fold in the past two decades. The effects of rapid weight loss on facial features has not been previously studied. We hypothesized that bariatric surgery will mimic the effects of aging thus giving the patient an older and less attractive appearance. Methods Consecutive patients were enrolled from the bariatric surgical clinic at our institution. Pre and post weight loss photographs were taken and used to generate two surveys. The surveys were distributed through social media to assess the difference between the preoperative and postoperative facial photos, in terms of patients' perceived age and overall attractiveness. 102 respondents completed the first survey and 95 respondents completed the second survey. Results Of the 14 patients, five showed statistically significant change in perceived age (three more likely to be perceived older and two less likely to be perceived older). The patients were assessed to be more attractive postoperatively, which showed statistical significance. Conclusions Weight loss does affect facial aesthetics. Mild weight loss is perceived by survey respondents to give the appearance of a younger but less attractive patient, while substantial weight loss is perceived to give the appearance of an older but more attractive patient.

Bariatric surgery has evolved from a surgical measure for treating morbid obesity to an epochal remedy for treating metabolic syndrome as a whole, which is represented by type 2 diabetes mellitus. Numerous clinical trials have advocated bariatric or metabolic surgery over nonsurgical interventions because of markedly superior metabolic outcomes in morbidly obese patients who satisfy traditional criteria for bariatric surgery (body mass index [BMI] >$35kg/m^2$) and in less obese or simply overweight patients. Nevertheless, not all diabetes patients achieve the most desirable outcomes; i.e., diabetes remission after metabolic surgery. Thus, candidates for metabolic surgery should be carefully selected based on comprehensive preoperative assessments of the risk-benefit ratio. Predictors for diabetes remission after metabolic surgery may be classified into two groups based on mechanism of action. The first is indices for preserved pancreatic beta-cell function, including younger age, shorter duration of diabetes, and higher C-peptide level. The second is the potential for an insulin resistance reduction, including higher baseline BMI and visceral fat area. Several prediction models for diabetes remission have been suggested by merging these two to guide the joint decision-making process between clinicians and patients. Three such models, DiaRem, ABCD, and individualized metabolic surgery scores, provide an intuitive scoring system and have been validated in an independent external cohort and can be utilized in routine clinical practice. These prediction models need further validation in various ethnicities to ensure universal applicability.

Obesity is a major public health problem worldwide, with several methods having been proposed as a means of weight loss. If diet, exercise, and medication are insufficient, a healthcare professional may suggest weight loss treatments, including bariatric surgery or medical devices. Antiobesity medical devices are an option for patients who do not want to undergo bariatric surgery. Compared with bariatric surgery, medical devices have the advantage of being reversible and easier to operate. The U.S. Food and Drug Administration (FDA) regulates medical devices, including those used for weight loss and weight management. This article provides an overview of the FDA-regulated weight loss and weight management devices.

This study examined the effects of postoperative medical nutrition therapy on patients who had undergone bariatric surgery. Eighty seven patients who underwent bariatic-surgery at Yeouido St. Mary's Hospital from January 2007 to April 2009 were evaluated. The bariatric surgery patients included 42 Laparoscopic Roux-en Y gastric bypass (LRYGB) and 45 Laparoscopic adjustable gastric banding (LAGB) patients. Weight loss was more significant after LRYGB than after LAGB after 9 months (p<0.05). The LRYGB group was more satisfied with the weight loss (LRYGB 4.4/5.0, LAGB 3.0/5.0 p<0.001). The mean albumin, hemoglobin and hematocrit levels were significantly lower in the LRYGB group than in the LAGB group at the time of discharge (p<0.05~0.001). The GOT/GPT was significantly higher in the LRYGB group at the time of the operation than the LAGB group (p<0.01). The LRYGB group showed significantly lower intakes of total energy, carbohydrates, protein and fat from 1 week after surgery than the LAGB group. Multiple regression showed that the weight change after LRYGB was significantly more associated with the intakes of total energy at 1 week after surgery (p<0.01), SWS (sweets and high-calorie beverages) at 1 and 6 months after surgery (p<0.001), and fat at 3 months after surgery (p<0.01). In addition, LAGB was significantly more associated with the intakes of protein and NLS (non-liquid sweets) at 1 week after surgery (p<0.001, p<0.01), carbohydrate at 1 months after surgery (p<0.01), total energy at 3 months after surgery (p<0.001), HCL (high-calorie liquids) at 6 months after surgery (p<0.05), and fat at 9 months after surgery (p<0.01). These results suggest that continuous-follow-up medical nutrition therapy is needed according to the types of bariatric surgery, particularly during the weight loss phase (the first 1 week to 12 months).
