Pregnancy and bariatric surgery

Primary care for women and other patients with similar reproductive potential can include a discussion about pregnancy and, depending on the patient's intent, contraceptive care or preconception care. Folic acid supplementation of at least 400 mcg per day is recommended to reduce the risk of neural tube defects, because many pregnancies are unplanned. Having a body mass index of 18.5 to 24.9 kg per m2 before pregnancy also reduces complications. Patients with a history of bariatric surgery should delay pregnancy for at least 12 months post-procedure and ensure that their nutritional status is adequate before conception...

Metabolic bariatric surgery (MBS) helps reduce comorbidities, such as hypertension and gestational diabetes, and is more effective than diet management for women with obesity-related health issues. Vitamin B12 , vitamin D, and iron play important roles in ensuring the health of a neonate. However, pregnancies occurring after MBS may face complications related to micronutrient deficiencies, particularly of vitamins B12 and D and iron. This study aimed to investigate the vitamin B12 , vitamin D, ferritin, and iron status of pregnant women who underwent MBS compared with women without MBS history...

BACKGROUND: Obesity is an increasing problem, even in young women of reproductive age. Obesity has a negative impact on conception, the course of pregnancy, and neonatal outcomes. Caring for obese pregnant women has becoming an important aspect of standard prenatal care. The Guideline "Obesity and Pregnancy" of the German Society of Gynecology and Obstetrics aims to create evidence-based recommendations which can be used to improve the care of obese pregnant women. As obesity is a worldwide problem, many societies for obstetrics and gynecology have created national guidelines...

OBJECTIVE: To assess perinatal cardiac function in offspring of women with previous bariatric surgery and examine its association with maternal glucose control. DESIGN: Prospective study. SETTING: Maternity unit, UK. POPULATION: Fifty-four fetuses/neonates; 29 of post-bariatric surgery women and 25 of women without surgery. METHODS: Prospective, longitudinal observational study of pregnant women with and without previous bariatric surgery, matched for early pregnancy body mass index...

BACKGROUND: Bariatric surgery (BS) results in major and sustained weight loss and improves comorbidities in patients with obesity but can also lead to malnutrition, especially through severe malabsorption and/or surgical complications. Little is known about the efficacy of artificial nutrition (AN) in this setting. METHODS: In this case series, we describe data from consecutive severely malnourished patients after BS (resectional and non-resectional), managed by AN at our hospital unit over a 4-year period...

OBJECTIVE: to determine the effect of gestational weight gain and perinatal outcomes in obese women who underwent and did not undergo bariatric surgery. MATERIAL AND METHODS: a retrospective observational cohort study was conducted. The gestational weight gain was classified as insufficient, adequate or excessive according to the guidelines of the United States Institute of Medicine: 4.99-9.07 kg for body mass index (BMI) > 30 kg/m2. Weight gain was calculated as the difference between the weight at the first visit of the 1st trimester and the weight at the visit of the 3rd trimester...

Bariatric surgery (BS) has emerged as an efficient approach for addressing obesity, offering long-term benefits encompassing substantial weight loss and improving metabolic disorders. Many women of childbearing age opt for BS to enhance their health and well-being. The weight loss achieved through these procedures can positively impact pregnancy outcomes, but it's crucial to consider potential drawbacks. Micronutrient deficiencies, such as anemia resulting from iron or vitamin B12 deficiency, are a legitimate concern...

IMPORTANCE: Pregnancy weight gain may affect the association of bariatric surgery with postsurgery pregnancy outcomes. However, the association of pregnancy weight gain with bariatric surgery is unclear. OBJECTIVE: To compare pregnancy weight gain among women with a history of bariatric surgery vs those without and to investigate whether pregnancy weight gain differs by surgical procedure, surgery-to-conception interval, and/or surgery-to-conception weight loss...

In 2007, the Scandinavian Obesity Surgery Registry (SOReg) was started by the profession to monitor the results of bariatric surgery and to provide a high-quality database for research. In the end of August 2023, SOReg contains 88,379 patients (body mass index [BMI] 41.7 kg/m2 , 41.2 years, 77.1% females, gastric bypass 76.8%). In this narrative review, we demonstrate that preoperative weight loss is of value and that the laparoscopic double omega-loop technique is highly suitable for gastric bypass...

OBJECTIVE:  Pregnancy after bariatric surgery is a reality of the 21st century and therefore is essential that all obstetricians know how to manage it. The most prevalent nutritional deficiency is iron deficiency and, consequently, anemia. Although bariatric surgery and pregnancy are already risk factors for anemia, we evaluated in our study if there were any other risk factors and actions to improve hemoglobin levels in this population. METHODS:  We performed a retrospective cohort study, and performed frequency measurements and analyzes of odds ratio, X2 and Fisher exact test to evaluate the risk factors...

One in three women of reproductive age is obese. The mainstay treatment for obesity is bariatric surgery, and the following weight reduction results in a decrease in pregnancy adverse effects, including gestational diabetes mellitus, pregnancy-induced hypertension, and macrosomia. However, nutritional and vitamin deficiencies due to changes in the gastrointestinal tract after bariatric surgery are associated with an increase in the risk of fetal growth retardation and small for gestational-age neonates. The purpose of this review was to analyze the available recent literature on the subject of the management of pregnancy after bariatric surgery...

Preconception bariatric surgery improves obesity-related maternal pregnancy complications but may reduce the absorption of nutrients required for healthy fetal growth and development. Women who receive preconception nutritional support after bariatric surgery are less likely to have adverse pregnancy outcomes. This study aimed to investigate the provision of preconception and pregnancy-specific nutritional support for women having bariatric surgery in the UK. A mixed-methods survey was distributed to healthcare professionals working in obesity or maternity services between December 2018 and October 2019...

Chronic diseases are potential risk factors for pregnancy duration and neonatal outcomes. This narrative review aimed to summarize the research results on the specifics of pregnancy in women with obesity and after bariatric surgery. PubMed and Google Scholar databases were searched. Systematic reviews, meta-analyses, clinical trials, and references to identified articles from the last ten years (2013-2023) were included. Ultimately, 107 literature items were qualified. It has been shown that women with obesity planning pregnancy should reduce their body weight because obesity is a risk factor for adverse obstetric and neonatal outcomes...

INTRODUCTION: Obesity is the most common medical problem affecting reproductive-age women. To detect the prevalence of obesity, and bariatric surgeries (BSs) in reproductive-age women, and the impact of obesity vs. BSs on the subsequent pregnancy outcomes. MATERIAL AND METHODS: Obese-pregnant women, and women underwent BSs before the current pregnancy, with complete antenatal, and delivery records were included in the current study. Collected data were analyzed using MedCalc 20...

BACKGROUND: Bariatric surgery is increasingly performed in women of reproductive age. As bariatric surgery will result in postoperative rapid catabolic weight loss which potentially leads to fetal malnutrition and directly related impaired intra-uterine growth, it is advised to postpone pregnancy for at least 12-18 months after surgery. OBJECTIVES: To investigate the consequences of preconception gastric bypass surgery (pGB) on fetal growth parameters and maternal pregnancy outcome...

SUMMARY: There is a scarcity of literature relating to post-bariatric hypoglycaemia (PBH) in pregnancy. Recurrent hyperglycaemia and hypoglycaemia can have significant consequences for both the mother and the developing fetus. We describe a case of a young pregnant woman who was diagnosed with symptomatic PBH in the second trimester of pregnancy using continuous glucose monitoring (CGM) 3 years after Roux-en-Y gastric bypass (RYGB) surgery. Instigating a low glycaemic index and complex carbohydrate diet significantly improved the patient's glycaemic excursions...

Introduction: Bariatric surgery is routinely performed on obese women of reproductive age, most commonly with the laparoscopic sleeve gastrectomy (SG) and Roux-en-Y gastric bypass procedures (RYGB). This study analyzes the effects of postoperative pregnancy on excess BMI loss percentage (EBMIL%) after SG and RYGB. Methods: A retrospective study was conducted with 191 female patients of reproductive age between 20 and 40 years who underwent SG and RYGB performed at our institution between January 2017 and December 2018...

BACKGROUND: Gestational Diabetes Mellitus (GDM) and many other clinical variables have been associated with postpartum urinary incontinence (UI). However, the data are still restricted, and no study explored early- or late-onset GDM as a risk factor for this condition. We aimed to identify independent risk factors for postpartum UI, focusing on GDM and its early or late onset. METHODS: A nested case control derived from the Diamater cohort study included 517 pregnant women who submitted to a planned C-section and followed by 6-18 months after delivery according to the timing of GDM diagnosis: early-onset GDM (before 20 weeks) and late-onset GDM(24-28 weeks) and the occurrence of UI...

Bariatric surgery is increasingly used in women of childbearing age due to the rising prevalence of obesity and the effectiveness and availability of this treatment. Pregnancy in women with previous bariatric surgery deserves special attention. Weight loss induced by surgery reduces the risks that obesity poses to pregnancy. But on the other hand, decreased intake and malabsorption may increase the risk of malnutrition and micronutrient deficiency and negatively affect maternal and foetal health. The aim of this narrative review is to provide an updated analysis of the impact of different bariatric surgery techniques on mineral and micronutrient nutritional status during pregnancy and the possible effect on maternal-foetal health...

Youth-onset type 2 diabetes is a growing epidemic with a rising incidence worldwide. Although the pathogenesis and diagnosis of youth-onset type 2 diabetes are similar to adult-onset type 2 diabetes, youth-onset type 2 diabetes is unique, with greater insulin resistance, insulin hypersecretion, and faster progression of pancreatic beta cell function decline. Individuals with youth-onset type 2 diabetes also develop complications at higher rates within short periods of time compared to adults with type 2 diabetes or youth with type 1 diabetes...
