Introduction: Bulimia nervosa is a serious, potentially life-threatening eating disorder characterized by a cycle of bingeing andcompensatory behaviors such as self-induced vomiting to undo or compensate for the effects of binge eating. Case Presentation: We present a 24-year-old female patient with severe abdominal pain and distension after binge eating. Thispatient was admitted to the Chosun University hospital in Gwangju, Republic of Korea, on January 2017. In spite of conservativetreatment, the symptoms were more aggravated. Therefore, we decided to conduct operative intervention. After gastrotomy, massivebleeding showed on nasogastric tube and drain site, then disseminated intravascular coagulopathy was developed. On thethird postoperative day, the patient died despite of resuscitation. Conclusions: We should pay attention to gastric atony in bulimia nervosa. Therefore, we must prevent massive gastric dilation, constant gastrointestinal bleeding, and disseminated intravascular coagulopathy.

Background: Eating disorders have become increasingly prevalent over the years,the age at which they appear has decreased, and they can lead to serious illness or death. Therefore, the number of studies on the matter has increased. Eating disorders like anorexia nervosa (AN) and bulimia nervosa (BN) are affected by many factors including mental illnesses that can have serious physical and psychological consequences. Accordingly, the present study aimed to compare the clinical and metabolic features of patients with AN and BN and identify potential biomarkers for distinguishing between the two disorders. Methods: Clinical data of 41 participants who sought treatment for eating disorders between 2012 and 2022, including 29 AN patients and 12 BN patients, were obtained from NPIstanbul Brain Hospital in Istanbul, Turkey. The study included the clinical variables of both outpatient and inpatient treatments. Principal component analysis (PCA) was utilized to gain insights into differentiating AN and BN patients based on clinical characteristics, while machine learning techniques were applied to identify eating disorders. Findings: The study found that thyroid hormone levels in patients with AN and BN were influenced by non-thyroidal illness syndrome (NTIS), which could be attributed to various factors, including psychiatric disorders, substance abuse, and medication use. Lipid profile comparisons revealed higher triglyceride levels in the BN group (P<0. 05), indicating increased triglyceride synthesis and storage as an energy source. Liver function tests showed lower levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in BN patients (P<0. 05), while higher prolactin levels (P<0. 05) suggested an altered hypothalamicpituitary-gonadal axis. Imbalances in minerals such as calcium and magnesium (P<0. 05) were observed in individuals with eating disorders. PCA effectively differentiated AN and BN patients based on clinical features, and the Naïve Bayes (NB) model showed promising results in identifying eating disorders. Conclusion: The findings of the study provide important insights into AN and BN patients’ clinical features and may help guide future research and treatment strategies for these conditions.

Purpose: Obesity has been identified as a risk factor for the development of bulimia nervosa (BN) in those who try to lose weight. The purpose of the present study was to examine the effect of walking exercise in order to provide a method for overcoming bulimia nervosa in obese young women suffering from bulimia nervosa. Methods: Twenty obese women with bulimia nervosa (body mass index [BMI]>30) and a mean age of 22.00 ± 1.50 years volunteered to participate in this study. They were randomly assigned to exercise (n=10) and control (n=10) groups. Both groups underwent anthropometric measurements and blood analysis before and after the training program. Exercise program included 30-minute walking sessions at 50-75% of maximal heart rate, 3 days per week and for 2 months.Results: After 2 months significant changes were observed in all anthropometric variables (P<0.001). Percent body fat, fat mass, BMI, body weight and lean mass changes in response to training were significant in the exercise group (P<0.001). Conclusion: This study demonstrated that moderate aerobic exercises such as moderate walking are suitable behavior therapies for overcoming bulimia nervosa in obese young women.

Background: According to previous studies, a number of executive functions are impaired in people with bulimia nervosa. Accordingly, the aim of this study was to identify the most function impairments involved in patients with bulimia nervosa. Materials and Methods: The present study is a descriptive survey, and according to the method of implementation, is a systematic review study. A literature search was conducted by using the following electronic databases including scientific information databases )SID), CINAHL, Scopus, Web of Science, google scholar, PubMed, ScienceDirect, Medlib, Magiran, and Medline from 1991 through 2017. With executive actions involved in patients with bulimia nervosa, a search was done using the keywords of executive actions, working memory, attention, inhibition, reasoning and planning, organizing, self-regulation, inhibition, retention and conversion, self-regulation, cognitive flexibility, inhibitory control, speed processing, repositioning, decision-making, self-control, anorexia nervosa, and their combination with bulimia nervosa and similar terms )emotional eating). The content of all articles, after extraction from the databases, was evaluated by the PRISMA checklist, and the content analysis was used to examine data. Results: After the search and evaluation of the studies, the final analysis was carried out on 63 articles. The findings of this study showed that the executive actions involved in bulimia nervosa fall into five categories: attention, decision-making, inhibition, working memory, and set-shifting. Conclusion: Based on the results, drawing on the areas identified in the field of executive functions involved in patients with bulimia nervosa can be used as a conceptual map for more coherent studies and the design of extensive interventions.
