Abstract:
Objective:To summarize the characteristics and management experience of pregnancy after bariatric surgery.Methods:A retrospective analysis was conducted on four pregnant patients who had undergone pre-pregnant bariatric surgery and delivered at the Department of Obstetrics and Gynecology, Beijing Tsinghua Changgung Hospital, from January 2021 to December 2023. The analysis included the type of bariatric surgery, the interval between bariatric surgery and pregnancy, pregnancy complications, and neonatal birth conditions. Descriptive statistical analysis was used.Results:Among the four patients, two were primiparas and two were multiparas. All patients were obese (body mass index≥27.5 kg/m2) before undergoing sleeve gastrectomy. Before the current pregnancy, three patients had a normal body mass index, while one patient remained obese (body mass index 30.5 kg/m2). The interval between bariatric surgery and pregnancy exceeded one year for three patients (14, 14, and 60 months, respectively), while one patient became pregnant 10 months after surgery. Three patients developed normocytic anemia in early pregnancy, with the lowest hemoglobin levels of 101 to 106 g/L. After nutritional guidance and medication, hemoglobin levels returned to normal before delivery. One patient experienced a threatened late miscarriage at 26 weeks of gestation, which was successfully managed with tocolytic therapy. One patient was diagnosed with gestational diabetes at 27 weeks of gestation and achieved satisfactory blood glucose control through dietary and exercise guidance. Oral glucose tolerance tests for all four patients showed low fasting blood glucose levels (3.8-4.5 mmol/L) and 2-hour postprandial blood glucose levels (3.5-6.1 mmol/L). All four patients delivered at term, with no cases of small for gestational age infants.Conclusions:Pregnancy after bariatric surgery is prone to maternal nutrient deficiencies and blood glucose fluctuations. Multidisciplinary collaborative management and individualized nutritional guidance are recommended to reduce the risk of related complications.
