Contraception, Menstruation, and Sexuality after Bariatric Surgery: a Prospective Cohort Study

Effects of bariatric surgery on the menstruation- and reproductive-related hormones of women with obesity without polycystic ovary syndrome: a systematic review and meta-analysis

BACKGROUND

Bariatric surgery is an effective treatment for severe obesity. Several studies have been conducted on the effects of bariatric surgery on the reproductive function of women with obesity who do not have polycystic ovary syndrome (PCOS).

OBJECTIVES

To evaluate the effects of bariatric surgery on the menstruation and reproductive related hormones of women of childbearing age with who do not have PCOS.

SETTING

A systematic review and meta-analysis at a university hospital.

METHODS

Online databases were searched for all studies reporting the efficacy of bariatric surgery for women with obesity until March 2021. The language of publication was limited to English and Chinese. Incidence of abnormal menstruation and reproductive-related hormone levels were the primary outcomes.

RESULTS

Fifteen studies comprising 725 patients were enrolled in this meta-analysis. Results showed a significantly lower incidence of abnormal menstruation (relative risk: .40, 95% confidence interval [CI]: .20-.79, P = .008) after bariatric surgery. Moreover, bariatric surgery led to a decrease in serum insulin levels (mean difference [MD] = -13.12 mIU/L, 95% CI: -15.03 to -11.22, P < .00001), glucose (MD = -.91 mmol/L, 95% CI: -1.26 to -.56, P < .00001), triglyceride (MD = -.61 g/L, 95% CI: -.76 to -.46, P < .00001), total testosterone (MD = -.22 ng/mL, 95% CI: -.24 to -.20, P < .00001), dehydroepiandrosterone (DHEA) (MD = -25.34 μg/dL, 95% CI: -31.19 to -19.49, P < .00001), estradiol (MD = -25.13 pg/mL, 95% CI: -34.13 to -16.13, P < .00001), and anti-Mullerian hormone (AMH) (MD = -.40 ng/mL, 95% CI: -.67 to -.13, P = .003). Serum sex hormone binding globulin (SHBG) levels increased after bariatric surgery (MD = 43.99 nmol/L, 95% CI: 34.99-52.99, P < .00001).

CONCLUSION

Bariatric surgery can lower fasting insulin, glucose, and triglyceride levels, reduce the incidence of abnormal menstruation, decrease total serum testosterone, DHEA, estradiol, and AMH levels, and increase SHBG level for women with obesity of childbearing age who do not have PCOS. This meta-analysis indicated that bariatric surgery could be effective in improving reproductive function for women with severe obesity.

Women in larger bodies' experiences with contraception: a scoping review

Background

As the prevalence of obesity increases and the age of onset decreases, more women of reproductive age will be living in larger bodies. Research on weight-related efficacy and safety has informed clinical guidelines for routine and emergency contraceptive use by women with a higher body mass index; however, patient perspectives are needed to understand women in larger bodies’ experiences with contraception and contraceptive care. This scoping review summarizes the literature on women in larger bodies’ experiences with contraception with the goal of gaining a better understanding of the nature of these experiences and identifying gaps in the existing research.

Methods

Following Arksey and O’Malley’s framework, a scoping review of the literature was conducted. Four databases (PubMed, PsycINFO, SCOPUS, and CINAHL) were searched for peer-reviewed, empirical articles published in English between 2010 and 2020, with a focus on North America, Europe, Australia, and New Zealand. Data were summarized by identifying key themes in the reviewed literature.

Results

Twenty-nine articles meeting the eligibility criteria were reviewed. The literature was predominantly quantitative (n = 27), with only one qualitative study and one systematic review, respectively. Five themes were identified, including (1) use of contraception among women in larger bodies; (2) knowledge, attitudes towards and beliefs about contraception; (3) contraceptive (dis)satisfaction among women in larger bodies; (4) contraceptive counseling; and (5) barriers to contraception. The findings revealed that women in larger bodies may have unmet contraceptive care needs. Despite many articles addressing the need to improve contraceptive counseling for women in larger bodies (n = 26), few explored how women felt about their care (n = 2). Finally, only two articles focused on emergency contraception, indicating a need for further research.

Conclusion

This scoping review emphasizes the pressing need for qualitative research to explore women in larger bodies’ experiences with routine and emergency contraception, as well as receiving contraceptive counseling and care. Future research exploring the lived experiences of women in larger bodies is necessary to better characterize their contraceptive needs and identify avenues to improve patient care.

As obesity becomes more prevalent, more women of reproductive age will be living in larger bodies. This review highlights what is known about women in larger bodies’ experiences with contraception and suggests where future research is needed. We searched four databases for papers published in English from 2010 to 2020. Our review included 29 articles. Nearly all of the studies were quantitative, with one qualitative study and one review. Most articles talked about contraceptive use, but few of them included emergency contraception. Some papers highlighted women’s knowledge and opinions about contraception, whereas others talked about their contraceptive (dis)satisfaction. Many articles discussed contraceptive counseling. Finally, some papers considered potential barriers to contraception. Our findings suggest that women in larger bodies have unmet contraceptive needs. Notably, this review aimed to focus on patient experiences but women’s voices were rarely represented. Future qualitative research on women’s lived experiences will provide a better understanding of women in larger bodies’ contraceptive needs and suggest how care can be improved.

Pregnancy after bariatric surgery - a narrative literature review

The purpose of this review was to analyze the literature about pregnancy after bariatric surgery. We searched for available articles on the subject from the last decade (2010 to 2020). The positive impact of bariatric surgery on the level of comorbidities and pregnancy and neonatal outcomes cannot be overrated. Weight loss after bariatric surgery reduces the incidence of obesity-related conditions in pregnancy. A pregnancy in a woman after bariatric surgery should be considered a high-risk pregnancy and taken care of by a multidisciplinary team with appropriate micronutrient and vitamin supplementation provided. Optimum time to conception should be chosen following the international recommendations. Every woman after bariatric surgery should be aware of symptoms of surgical complications and immediately contact their surgeon in case of abdominal pain.

The effect of bariatric surgery on female sexual function: a cross-sectional study

The generally negative impact of obesity on female sexuality is well-established. The possible association between bariatric surgery, weight loss, and female sexuality is much less described. The aim of the study was to analyse the possible association between bariatric surgery and female sexual function. It was a cross-sectional study of 623 patients who underwent bariatric surgery between 1999 and 2017. Patients were recruited on the basis of medical records from the Military Institute of Medicine in Warsaw. Patients were invited to complete a questionnaire which consisted of self-designed demographic questions and Female Sexual Function Index (FSFI). The total FSFI score, as well as each subdomain, improved significantly after surgery. The prevalence of low score (< 26.55) was significantly lower after the surgery in comparison to the status prior to the procedure (36.3% vs. 57.5%; p < .001). There were no differences regarding the number of sexually active patients before and after the surgery (75.3% vs. 76.1%; p < .63). There were observed statistically significant, positive correlations between BMI decrease and each subdomain of the FSFI score as well as the total score. Weight loss surgery seems to decrease the risk of sexual dysfunction presence and the advantages are associated with the total BMI loss.

The Impact of Bariatric Surgery on Menstrual Abnormalities-a Cross-Sectional Study

INTRODUCTION

Obesity is associated with hyperestrogenism along with other hormonal abnormalities affecting the menstrual cycle. The most effective and decisive method of obesity treatment is bariatric surgery. The aim of this study was to analyze the impact of bariatric surgery on menstrual cycle, the incidence of menstrual abnormalities, hyperandrogenism manifestation, and contraception use.

MATERIALS AND METHODS

It was a cross-sectional study of 515 pre-menopausal women who had undergone bariatric surgery between 1999 and 2017 in a bariatric center. Data was collected via anonymous questionnaire, and the questions covered a 1-year period before the surgery and the last year before questionnaire completion.

RESULTS

Before the surgery, 38.6% of the patients reported irregular menstruations in comparison with 25.0% after bariatric surgery (RR = 0.65; 95%CI 0.53-0.79). The mean number of menstruations per year did not differ before and after surgery (10.2 ± 3.9 vs 10.4 ± 3.3; p < .45). There were no statistically significant differences in terms of prolonged menstruations, acne, and hirsutism prevalence. A total of 14.4% of patients before surgery reported estrogen-based contraception use in comparison with 15.0% after the surgery (p < .95). There were no significant differences in the frequency of OC use (11.0% before surgery vs 13.6% 12 months after the surgery vs 11.5% at the moment of survey administration; p < 0.46).

CONCLUSION

Bariatric surgery improves the regularity of the menstrual cycle in obese women in reproductive age. The lack of any changes in the combined hormonal contraception (CHC) use, especially OC, before and after bariatric surgery may be a result of a possibly low level of contraception counseling.

Pregnancy after bariatric surgery: Consensus recommendations for periconception, antenatal and postnatal care

The objective of the study is to provide evidence-based guidance on nutritional management and optimal care for pregnancy after bariatric surgery. A consensus meeting of international and multidisciplinary experts was held to identify relevant research questions in relation to pregnancy after bariatric surgery. A systematic search of available literature was performed, and the ADAPTE protocol for guideline development followed. All available evidence was graded and further discussed during group meetings to formulate recommendations. Where evidence of sufficient quality was lacking, the group made consensus recommendations based on expert clinical experience. The main outcome measures are timing of pregnancy, contraceptive choice, nutritional advice and supplementation, clinical follow-up of pregnancy, and breastfeeding. We provide recommendations for periconception, antenatal, and postnatal care for women following surgery. These recommendations are summarized in a table and print-friendly format. Women of reproductive age with a history of bariatric surgery should receive specialized care regarding their reproductive health. Many recommendations are not supported by high-quality evidence and warrant further research. These areas are highlighted in the paper.

I Am As Normal As Everyone Now. . . : Examination of Experiences of Patients Undergoing Bariatric Surgery According to Roy's Adaptation Model: A Qualitative Study

The aim of this study is to examine experiences of patients undergoing bariatric surgery according to Roy's adaptation model (RAM). This is a qualitative study with a phenomenological design. The sample included patients undergoing bariatric surgery (N: 32). Of all the patients 84.37% were female and 59.38% were married. According to results of the content analysis, adaptive patient behavior was described by the themes "My life has changed", Everything is beautiful" "I can cope" and "Luckily, I have them" and their nonadaptive behavior was described by the themes "What if I cannot succeed", "Bad news" and "So many people, so many views". Patients having bariatric surgery experience various difficulties in adapting to their life and bodies, but the surgery leads to improvements in their body image, social life, personal relationships, and maintenance of roles. However, some patients can be afraid of postoperative complications and experience anxiety about regaining weight.
