Patients' Perspectives on Dietary Patterns and Eating Behaviors During Weight Regain After Gastric Bypass Surgery.

PURPOSE: Food quality, energy intake, and various eating-related problems have been highlighted as some of the components influencing weight after bariatric surgery. This study aimed to increase our knowledge of patients' perspectives on dietary patterns and eating behaviors during weight regain after bariatric surgery. MATERIALS AND METHODS: We recruited 4 men and 12 women with obesity and the experience of weight regain after bariatric surgery at an obesity clinic in Stockholm, Sweden. Data were collected during 2018-2019. We conducted a qualitative study, carried out individual semi-structured interviews, and analyzed the recorded and transcribed interview data with thematic analysis. RESULTS: Participants had regained 12 to 71% from their lowest weight after gastric bypass surgery performed 3 to 15 years before. They perceived their dietary challenges as overwhelming and had not expected weight management, meal patterns, increasing portion sizes, and appealing energy-dense foods to be problematic after surgery. In addition, difficulties with disordered eating patterns, emotional eating, and increased alcohol intake further contributed to the weight management hurdles. Insufficient nutritional knowledge and lack of support limited participants' ability to avoid weight regain, leading to restrictive eating and dieting without sustained weight loss. CONCLUSION: Eating behavior and dietary factors such as lack of nutritional knowledge, emotional eating, or disorganized meal patterns contribute to difficulties with weight management after gastric bypass surgery. Improved counseling may help patients prepare for possible weight regain and remaining challenges with food and eating. The results highlight the importance of regular medical nutrition therapy after gastric bypass surgery.

Prospective study of weight loss and all-cause-, cardiovascular-, and cancer mortality.

Effects of repeated weight changes on mortality are not well established. In this prospective cohort study, we followed 34,346 individuals from 1997 to 2018 for all-cause mortality, and 2016 for cause-specific mortality. At baseline, participants self-reported amount and frequency of prior weight loss. During 20.6 (median) years of follow-up, we identified 5627 deaths; 1783 due to cancer and 1596 due to cardiovascular disease (CVD). We used Cox Proportional Hazards models to estimate multivariable-adjusted Hazard Ratios (HRs) and 95% confidence intervals (CI). Participants with a weight loss > 10 kg had higher rates of all-cause (HR 1.22; 95%CI 1.09-1.36) and CVD mortality (HR 1.27; 95%CI 1.01-1.59) compared to individuals with no weight loss. Men who had lost > 10 kg had higher all-cause (HR 1.55; 95%CI 1.31-1.84) and CVD mortality (HR 1.55; 95%CI 1.11-2.15) compared to men with no weight loss. Participants who had lost ≥ 5 kg three times or more prior to baseline had increased rates of all-cause (HR 1.16; 95%CI 1.03-1.30) and CVD mortality (HR 1.49; 95%CI 1.20-1.85) compared to participants with no weight loss. We found no association between weight loss and cancer mortality. We conclude that previous and repeated weight loss may increase all-cause and CVD mortality, especially in men.

Weight Loss History and Its Association with Self-Esteem and Eating Behaviors in Adolescents and Young Adults with Obesity.

INTRODUCTION: Previous weight loss attempts in young people with obesity may have influenced their beliefs about themselves and contributed to maladaptive eating behaviors. Therefore, we aimed to investigate the association between previous weight loss with self-esteem and different eating behaviors in adolescents and young adults with obesity seeking specialty obesity care. METHODS: We performed a cross-sectional study, where a total of 224 participants with obesity, aged 16-25, self-reported the amount and the frequency of previous weight loss of 5 kg or more. Self-esteem was assessed with Rosenberg's Self-Esteem Scale and eating behavior with the Three-Factor Eating Questionnaire-Revised21. Linear regression was used to analyze associations between the amount of weight loss (no weight loss, 5-10 kg, and >10 kg) and the frequency of weight loss ≥5 kg (0, 1, and ≥2 times) with self-esteem and eating behaviors. RESULTS: We found that both those who had lost 5-10 kg and those who had lost ≥5 kg twice or more, had statistically significantly higher cognitive restraint eating scores ß = 7.03 (95% CI: 0.004-14.05) and ß = 8.32 (95% CI: 1.20-15.43), respectively, compared to those who reported no previous weight loss. No other statistically significant associations were found. CONCLUSION: Previous weight loss in adolescents and young adults with obesity may be associated with a higher cognitive restraint eating behavior. Therefore, assessing weight loss history and eating behavior may be beneficial to better individualize obesity treatment.

Patients' Experiences of Weight Regain After Bariatric Surgery.

PURPOSE: Bariatric surgery is a successful obesity treatment; however, an estimated 1/5 of patients have regained more than 15% of their body weight 5 years post-surgery. To increase the understanding of patients who experienced weight regain after bariatric surgery, we conducted a qualitative study. MATERIALS AND METHODS: We recruited 16 adult participants (4 men, 12 women) at an obesity clinic in Stockholm, Sweden, 2018 to 2019, and performed semi-structured individual interviews. The transcribed recorded interview data was analyzed with thematic analysis. RESULTS: Participants had undergone gastric bypass surgery on average 10 years prior to study and regained 36% (range 12 to 71%) of their weight from their nadir. Participants experienced challenges such as eating in social settings, loneliness, family difficulties, increases in appetite, and physical and mental health problems, which distracted them from weight management. Participants responded to weight regain with emotional distress, particularly with hopelessness, discouragement, shame, and frustration (theme: loss of control and focus). Nonetheless, participants experienced remaining benefits from the surgery, despite weight regain. Social support, self-care, and behavioral strategies were perceived as facilitators for weight management (theme: reducing the burden of weight management). CONCLUSIONS: Weight regain after bariatric surgery was perceived to be an unexpected and difficult experience that induced hopelessness, discouragement, shame, and frustration. Results indicate that internal and external circumstances such as psychosocial factors, changes in appetite, and physical and mental health problems may contribute to loss of control over weight. Social support, self-care, and behavioral strategies might facilitate long-term post-surgical weight management.

Perceived and Preferred Social Support in Patients Experiencing Weight Regain After Bariatric Surgery-a Qualitative Study.

PURPOSE: While bariatric surgery generally shows successful weight loss outcomes in patients with obesity, weight regain exists. The aim of this qualitative study was to improve understanding of how patients with substantial weight regain after bariatric surgery experienced the support from family, friends, and healthcare providers, and what kind of support they had preferred. MATERIALS AND METHODS: Qualitative data were collected from semi-structured interviews with 16 participants. Mean weight regain from surgery to interview was 36%. The transcribed interviews were analyzed with thematic analysis. RESULTS: Two main themes and seven sub-themes were formulated. The theme, A lonely struggle, illustrates patients' feelings of abandonment and struggle during weight regain due to lack of support or unfavorable treatment. Participants commonly blamed themselves for re-gaining weight, and shame made them reluctant to engage in social activities or seek medical care. The theme, Others as sources of compassion and control, covers what support they desired, as well as had perceived to be helpful. Exercising or eating healthy with others was appreciated and felt supportive. Pro-active healthcare support and access to dietitians, physiotherapists, and psychological support were desired. CONCLUSION: To optimize the effect of bariatric surgery, support may need to be individualized and lifelong. Since shame and self-blame in patients with weight regain may hinder seeking professional help, care providers may need to initiate follow-up visits. Empathetic and non-judgmental support, access to multidisciplinary healthcare team, as well as peer-support groups may be beneficial to counteract weight regain post-bariatric surgery.
