Care of Patients After Bariatric Surgery in the Periconceptional and Perinatal Periods.
Review in Nutrients, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Obesity in women of reproductive age is a major issue. It is associated with reduced fertility and an increased risk of obstetric and perinatal complications. Bariatric surgery is the most effective treatment for severe obesity, leading to substantial weight reduction, improvement of metabolic disorders, and enhanced fertility. Consequently, an increasing number of women are becoming pregnant after undergoing bariatric surgery. The aim of this paper is to review current recommendations and research data regarding the care of women after bariatric surgery in the periconceptional and perinatal periods, as well as throughout pregnancy, delivery, and the postpartum period. Research suggests that pregnancy after bariatric surgery is associated with a lower risk of gestational diabetes, hypertension, preeclampsia, and fetal macrosomia compared with pregnancies in women with similar baseline BMI (body mass index) who have not undergone surgical treatment. At the same time, an increased risk is observed for low birth weight, maternal micro- and macronutrient deficiencies, and complications characteristic of bariatric procedures, such as dumping syndrome or intra-abdominal hernias. Most scientific societies recommend postponing pregnancy planning for 12-18 months after surgery and using effective contraception, preferably methods that do not require gastrointestinal absorption. Regular monitoring of laboratory parameters, individually tailored supplementation, and interdisciplinary care are essential for the safe management of pregnancy after bariatric surgery. In particular, care should include achieving a stable body weight before conception, monitoring of nutritional status, verifying proper weight gain during pregnancy, and considering alternative methods for gestational diabetes screening (e.g., glycaemic monitoring instead of oral glucose tolerance testing) due to the risk of dumping syndrome. Appropriate preparation for pregnancy and proper management throughout its course allow for reducing the risk of perinatal complications. Bariatric surgery itself is not a contraindication to vaginal delivery.
