Self-image after bariatric surgery and its relationship to gender, excess skin and health-related quality of life

Effects of bariatric surgery on sexual function and fertility: A narrative review

Obesity has emerged as a prevalent global health concern, with its detrimental effects on the reproductive system and sexual function garnering increasing attention. Both men and women affected by obesity face a heightened risk of fertility challenges and sexual dysfunction. Although fertility and sexual function are distinct topics, they are intricately linked and mutually influential in both medical and societal contexts. Bariatric surgery (BS) has generated promising results in alleviating sexual dysfunction and enhancing fertility, results which are often gender specific. In men, improvements in sexual function can often be attributed to weight loss and subsequent optimizations in sex hormone levels. However, improving female sexual function may be related to a range of factors beyond weight loss. Bariatric procedures have shown limited benefits for male fertility; in fact, in some situations it can even be detrimental, leading to a decrease in sperm count and quality. Conversely, BS may positively impact female fertility, improving pregnancy and neonatal outcomes. Nevertheless, it is essential to consider the potential risks related to the adverse effects of malnutrition and rapid weight loss following BS, making it advisable to wait for 12-18 months before attempting pregnancy.

Association between obesity and female sexual dysfunction: a review

INTRODUCTION

Obesity is a global health crisis that has been growing over the past few decades. The economic burden associated with obesity is substantial as it is associated with multiple disabling chronic diseases, such as cardiovascular disease, certain cancers, osteoarthritis, chronic pain, and mental illness. Obesity is known to be a risk factor for sexual dysfunction in men, but this association is less well understood in women.

AIMS

To provide a narrative review of the available literature on the relationship between overweight/obesity and female sexual dysfunction, elaborate on the possible mechanisms explaining this association, and discuss the effects of weight loss on sexual function in those with obesity.

METHODS

A search of the medical literature was carried out in PubMed and Medline, focusing on original research and systematic reviews of original research on obesity and sexual function in women.

RESULTS

The relationship between obesity and female sexual function is not consistent across studies. While women with obesity are more likely to have worse sexual function and avoid sexual activity, many studies have failed to identify these associations. Lifestyle changes resulting in weight loss lead to better sexual function, and bariatric surgery has been shown to improve sexual function in the first couple of years following the procedure; yet, the long-term effects of weight loss and bariatric surgery are still uncertain.

CONCLUSIONS

The evidence on the relationship between obesity and female sexual function is mixed. Nevertheless, weight loss has been shown to improve sexual function in women with obesity. The impact of weight loss medications and the long-term effect of bariatric surgery on female sexual function require further study.

Factors Associated with Excess Skin After Bariatric Surgery: a Mixed-Method Study

PURPOSE

After metabolic and bariatric surgery (MBS), many patients have excess skin (ES), which can cause inconveniences. Identifying factors related to ES quantity and inconveniences is crucial to inform interventions. The aim of this study was to identify sociodemographic, physical, psychosocial, and behavioral factors associated with ES quantity and inconveniences.

MATERIALS AND METHODS

A mixed-method study with a sequential explanatory design was conducted with 124 adults (92% women, Mage 46.5 ± 9.9 years, Mtime post-MBS 34.2 ± 27.6 months). During phase I, ES quantity (arms, abdomen, thighs) and inconveniences and sociodemographic, anthropometric, clinical, and behavioral outcomes were assessed. In phase II, 7 focus groups were performed with 37 participants from phase I. A triangulation protocol was completed to identify convergences, complementarities, and dissonances from quantitative and qualitative data.

RESULTS

Quantitative data indicate only ES quantity on arms was associated with ES inconveniences on arms (r = .36, p < .01). Total ES quantity was associated with maximal body mass index (BMI) reached pre-MBS (r = .48, p < .05) and current BMI (r = .35, p < .05). Greater ES inconvenience was associated with higher social physique anxiety and age (R2 = .50, p < .01). Qualitative data were summarized into 4 themes: psychosocial experiences living with ES, physical ailments due to ES, essential support and unmet needs, and beliefs of ES quantity causes.

CONCLUSION

Measured ES quantity is related to higher BMI, but not reported inconveniences. Greater self-reported ES quantity and inconveniences were associated with body image concerns.

Corset trunkoplasty is able to preserve postoperative abdominal skin sensation in massive weight loss patients

Conventional abdominoplasty techniques commonly cause postoperative peri- and infraumbilical skin hypesthesia due to abdominal skin flap undermining. The aim of this study was to evaluate abdominal skin sensation after corset trunkoplasty in massive weight loss patients. Forty-nine massive weight loss patients suffering from excess skin underwent corset trunkoplasty between April 2017 and July 2021. Patient demographics and perioperative complications were recorded. Sensibility of the abdominal skin was measured in three qualities postoperatively using a Semmes-Weinstein monofilament, Tip-Therm^® device for thermal sensation and a cotton wooden stick for sharp/blunt discrimination. Results were compared with a control group of healthy individuals to create a baseline. Revision surgery for major complications was necessary in five cases (10%) including hematoma and major wound healing disturbances. Minor complications that did not require surgical intervention were observed in eight cases (16%). Postoperative abdominal sensibility did not show any significant difference between the patient and the control group in all 16 measured areas. Sharp/blunt and thermal discrimination was positive in all patients for the whole abdominal surface area. The corset trunkoplasty technique is able to address both horizontal and vertical soft tissue excess in massive weight loss patients and at the same time limits loss of sensibility of the abdominal skin. Compared to conventional abdominoplasty techniques the abdominal sensation can mainly be preserved due to absence of undermining abdominal skin flaps.

The role of body image in obese identity changes post bariatric surgery

PURPOSE

Body image is a multidimensional construct that encompasses perceptions about body size, emotions, and cognition about physical appearance. Obese identity is related to body image in the lifetime, and according to scientific literature body image dissatisfaction among obese patient persist after bariatric surgery. The objective of this review is to examine the body image changes in patients with obesity pre-and post-bariatric surgery.

METHODS

We have carried out a systematic review of literature on PubMed. Initially, 169 publications have been identified, but in total, in compliance with inclusion and exclusion criteria, 15 studies have been analyzed.

RESULTS

According to the examined literature, body image does not change after bariatric surgery. These patients will be difficult to adapt for a new body, because there is a persistent obese view of self. Furthermore, ex-obese patients are dissatisfied with the excessive skin after bariatric surgery. Excessive body weight, and negative self-image are replaced with dissatisfaction with excessive skin, and the factors associated with body image stability are still unknown.

CONCLUSION

Literature examination raises the issue of body image dissatisfaction, but does not explain why it varies so widely across bariatric patients. Obese identity is related to body image across the lifetime and is an important factor of post-surgical outcomes. Longitudinal studies based on ideal body image pre- and post- bariatric surgery and evidence-based controlled studies on psychotherapeutic treatment for body image dissatisfaction are strongly recommended. Psychotherapy could improve body image quality and wellbeing.

Investigation of Body Awareness and Affecting Factors in Patients with Bariatric Surgery

BACKGROUND

Major weight loss after bariatric surgery (BS) makes the body sensitive to the environment. The factors associated with body awareness are unknown in patients with BS. In this study, we aimed to investigate the body awareness and the affecting factors in patients with BS.

METHODS

Our study included 81 patients who had BS at least 6 months ago and 40 people of the same age and gender who had not. Participants' body awareness was evaluated with the Body Awareness Questionnaire, body compositions with bioelectric impedance device, joint position sensation (JPS) with photography method, physical activity level with International Physical Activity Questionnaire, quality of life with the Short Form-36, depression status with the Beck Depression Inventory, and cognition with the Montreal Cognitive Assessment Scale. Mann-Whitney U and Chi-square tests were used for the comparison of the groups, and Spearman correlation analysis was used for in-group correlation analysis.

RESULTS

Body awareness was found to be higher in patients with BS compared to the control group (p = 0.002). Body awareness had a positive correlation with cognition (r = 0.277, p = 0.012), quality of life sub-scales (r = 0.245-0.374, p < 0.05), the amount of change in total body weight (r = 0.241, p = 0.027), and body mass index (BMI) (r = 0.269, p = 0.032); negative correlation with depression (r =  - 0.409, p = 0.016) and deviation in the JPS (r =  - 0.223, p = 0.046).

CONCLUSION

Body awareness of patients with BS was found to be high after surgery. Body awareness in patients with BS is associated with the amount of weight loss and BMI, depression, cognition, JPS, and health-related quality of life.

Physical measurements and patients’ perception of excess skin on arms and thighs before and after bariatric surgery

Background

Bariatric surgery is an effective weight loss method for patients with obesity. One side effect of bariatric surgery is uncomfortable excess skin. Much remains to be learned about physical measurements and patients’ subjective perceptions of it. Here, we investigated the pre- to post-bariatric changes in patients’ perception and physical measurements of the skin on the arms and thighs, in order to find possible subgroups especially affected by post-operative excess skin and to identify predicting factors.

Methods

One hundred forty-seven patients eligible for bariatric surgery completed the Sahlgrenska Excess Skin Questionnaire (SESQ) and underwent measurements of their skin before and 18 months after the procedure.

Results

Although most physical measurements decreased post-operatively, many patients reported increased discomfort. We identified one subgroup particularly prone to report excess skin on the arms post-operatively: women with high discomfort from excess skin on the arms and high body mass index (BMI), pre-operatively. Ptosis of the excess skin seems to be a feasible measurement for predicting post-operative discomfort. For every centimetre of ptosis pre-operatively, patients had 1.37- and 1.31-fold higher odds of achieving a score for post-operative discomfort from excess skin on the upper arms and thighs, respectively, of ≥ 6 (on a 0–10 scale).

Conclusions

We identified a subgroup especially affected by discomforting excess skin on arms and thighs after weight loss. Furthermore, we suggest a pre-operative pro-operative ptosis measuring to predict post-operative discomfort level. The result of this study further increases the knowledge of excess skin and should be useful in further improving patient education.

Obesity, Body Image Dissatisfaction, and Sexual Dysfunction: A Narrative Review

With approximately two-thirds of the United States adult population classified as overweight or obese, obesity remains a critical public health concern. Obesity not only contributes to several health complications including type 2 diabetes mellitus and cardiovascular disease, but the condition is also associated with sexual dysfunction in both women and men. Despite evidence linking obesity and its concomitant pathophysiology to sexual problems, the potential roles of psychosocial factors such as body image are understudied. This narrative review evaluates the research linkages between obesity and sexual dysfunction, with particular attention to the potential effects of body image dissatisfaction. A literature search of biomedical and psychological databases was used to identify research pertaining to obesity, sexual function, and/or body image constructs. The pathophysiological effects of obesity on sexual function are well-documented in mechanistic studies and animal trials, often with corroboration in human clinical samples. However, very few studies examine obesity, body image, and sexual function in tandem. Body image dissatisfaction appears to independently impinge upon the sexual response cycle and mental health outcomes, irrespective of body weight. While obesity is often associated with negative body image appraisal, it is unclear whether these constructs exert additive, synergistic, or antagonistic effects on sexual responsivity. Additionally, overweight/obese individuals who exhibit higher levels of body image satisfaction or self-confidence appear to be protected from the deleterious effects of obesity on sexual satisfaction, at least to some extent. Greater reliance upon conceptual/theoretical models from the body image literature may better clarify the relationships between these constructs.

Health state utilities for economic evaluation of bariatric surgery: A comprehensive systematic review and meta-analysis

Health state utilities (HSUs) are health economic metrics that capture and assess health-related quality of life (HRQoL). They are essential in health-economic evaluations when calculating quality-adjusted life years. We investigated published studies reporting bariatric surgery-related HSUs elicited through direct or indirect (multiattribute utility instrument [MAUI]) patient-reported methods (PROSPERO registration number: CRD42019131725). Mean HSUs for different time points and HSU changes over time (where feasible) were meta-analysed using random-effects models. Of the 950 potentially relevant identified studies, n = 28 (2004-2018) qualified for data extraction, with n = 85 unique HSUs elicited mainly from the EQ-5D (88%). Most (75%) studies were published after 2013. The follow-up duration varied between studies and was often limited to 12 months. The pooled mean HSU was 0.72 (0.67-0.76) at baseline/presurgery (n = 18) and 0.84 (0.79-0.89) one-year postsurgery (n = 11), indicating a 0.11 (0.09-0.14) utility unit increment. EQ-5D showed the similar results. This positive difference can be partially explained by BMI and/or co-morbidities status improvement. This study provides a valuable summary of HSUs to future bariatric surgery-related cost-utility models. However, more well-designed higher-quality bariatric-related HSU studies are expected for future reviews to improve the available evidence. We suggest that researchers select an MAUI that is preferentially sensitive to the study population.

Eating attitudes, perceptions of body image and patient quality of life before and after bariatric surgery

AIM

This study examined eating attitudes, perceptions of body image and quality of life of patients before and after bariatric surgery.

METHODS

This prospective, descriptive study was conducted with fifty patients between April 23, 2018 and November 05, 2018. The data were collected by a survey form, the Three-Factor Eating Questionnaire, the Body Image Perception Questionnaire and SF-36 Quality of Life Questionnaire. The data collection instruments were applied before the surgery and at 1, 3 and 6 months following the surgery.

RESULTS

The mean age of the patients was 36.34 ± 10.89 years, 78% were females, 44% were university graduates, 80% were married, 78% had a child, 70% were employed, 80% were morbidly obese before the surgery, and 36% were morbidly obese at the first month following the surgery. It was also determined that there was no morbid obesity among the patients, and 84% of the patients were obese at the third month following the surgery. At the sixth postoperative month, 24% of the patients were found to be obese, and 8% had normal weight. It was determined that the patients' eating attitudes and behaviours changed significantly after the surgery in comparison to their pre-surgery values (p = 0.001). The body image perceptions and quality of life of the patients during the postoperative period were found to be significantly higher in comparison to their preoperative values (p = 0.001).

CONCLUSION

This study showed that multidimensional evaluation of patients and implementation of nursing interventions contributed positively to individuals undergoing bariatric surgery based on healthy lifestyle behaviours.

Review: Sex-Specific Aspects in the Bariatric Treatment of Severely Obese Women

This systematic literature review aims to point out sex-specific special features that are important in the bariatric treatment of women suffering from severe obesity. A systematic literature search was carried out according to Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. After the literature selection, the following categories were determined: sexuality and sexual function; contraception; fertility; sex hormones and polycystic ovary syndrome; menopause and osteoporosis; pregnancy and breastfeeding; pelvic floor disorders and urinary incontinence; female-specific cancer; and metabolism, outcome, and quality of life. For each category, the current status of research is illuminated and implications for bariatric treatment are determined. A summary that includes key messages is given for each subsection. An overall result of this paper is an understanding that sex-specific risks that follow or result from bariatric surgery should be considered more in aftercare. In order to increase the evidence, further research focusing on sex-specific differences in the outcome of bariatric surgery and promising treatment approaches to female-specific diseases is needed. Nevertheless, bariatric surgery shows good potential in the treatment of sex-specific aspects for severely obese women that goes far beyond mere weight loss and reduction of metabolic risks.

Patient Perspective in Obesity Surgery: Goals for Weight Loss and Improvement of Body Shape in a Prospective Cohort Study

OBJECTIVE

Obesity surgery provides sustainable weight loss, improvement of comorbidities, and improved quality of life (QOL). There is few evidence on the patient perspective and goals. This study compared expected and achieved weight loss, body shape, and QOL.

METHODS

Patients completed the Moorehead-Ardelt QOL questionnaire (MAQOL) and questionnaires on actual and expected weight loss and body shape, comorbidities, and goals of obesity surgery preoperatively and within 24 months postoperatively.

RESULTS

44 patients completed questionnaires pre- and postoperatively. BMI, MAQOL and comorbidities significantly improved postoperatively. Patients' expected weight loss goal corresponded to a postoperative BMI of 32.6 ± 5.6 kg/m2 and was not different from their achieved BMI within 24 months after surgery (33.9 ± 6.3 kg/m2, p = 0.276). Self-reported body shape improved but did not reach preoperatively expected goals. During the weight loss period, patients adapted their weight loss and body shape goals to higher levels. Patients attributed a higher part of their success in weight loss to surgery postoperatively (79.5 ± 22.0 vs. 89.1 ± 18.4%, p = 0.028).

CONCLUSION

Patients lost as much weight as they had expected and later modified the goals to even greater weight loss. Body shape improved but did not reach expected levels. QOL improved independently from weight loss and body shape. Patients attributed successful weight loss predominantly to surgery.
