Pregnancy in Women with Previous Bariatric Surgery: Summary of Recommendations
Appropriate selection of the bariatric surgical technique. Non-malabsorptive techniques should, in general, be preferred.
Appropriate follow-up after bariatric surgery, with the necessary supplementation to prevent and treat possible nutritional deficiencies.
Preferably, the onset of pregnancy should be delayed by 12–18 months after bariatric surgery. Pre-conceptional clinical and nutritional assessment is recommended.
Follow-up during pregnancy should be carried out by a multidisciplinary team.
Close monitoring of the patient if oral tolerance is inadequate or vomiting occurs. It is advisable to increase the thiamine dose to 100–300 mg/day.
Monitoring of maternal weight gain and intrauterine growth. Consider oral nutritional supplements and/or pancreatic enzymes.
Preventive supplementation with minerals and micronutrients, at the necessary dose, depending on the type of bariatric surgery and clinical and analytical evolution.
Iodine recommendations are similar to those for women who have not undergone bariatric surgery.
Screening for gestational complications, following specific protocols. In the case of gestational diabetes, it is recommended to avoid oral glucose overload.
Monitoring for the occurrence of surgical complications, such as internal hernia, a serious but rare clinical condition that requires a specific diagnostic approach and treatment.
Encourage lactation with a close clinical and nutritional follow-up.
