[Pregnancy after bariatric surgery].

Area of Science:

• Obstetrics and Gynecology
• Bariatric Surgery Outcomes
• Maternal-Fetal Medicine

Background:

• Pregnancy after bariatric surgery is influenced by obesity, surgical method, weight loss, and adherence to medical advice.
• Nutritional deficiencies are a significant concern for pregnant individuals post-bariatric surgery.

Purpose of the Study:

• To explore the unique considerations, risks, and outcomes of pregnancy after bariatric surgery.
• To assess the incidence of intestinal complications during pregnancy and cesarean sections post-bariatric surgery.
• To evaluate fetal risks, including prematurity, growth restriction, and birth defects, as well as maternal outcomes like gestational diabetes and hypertension.

Main Methods:

• Review of existing literature and clinical data on pregnancy outcomes following various bariatric procedures.
• Analysis of maternal and fetal complications, including nutritional status, intestinal issues, and delivery complications.
• Comparison of outcomes with general pregnancy populations where applicable.

Main Results:

• Pregnant individuals face risks of nutritional deficiencies and potential intestinal complications, though the latter's increased incidence during pregnancy or C-section remains unclear.
• Fetal risks include prematurity and fetal growth restriction, but the risk of birth defects is not generally increased, except in specific nutrient deficiencies.
• Maternal health benefits observed include a decreased incidence of gestational diabetes and hypertension.

Conclusions:

• Pregnancy post-bariatric surgery requires careful management due to specific maternal and fetal risks, particularly nutritional deficiencies.
• While some risks are elevated (prematurity, growth restriction), others like birth defects and gestational complications may be reduced.
• Long-term follow-up is necessary to assess postnatal outcomes, including potential epigenetic modifications.
