Fetal neural tube defects in pregnant women previously submitted to bariatric surgery: more attention to a new emerging entity.

The sharp increase in bariatric surgery in women of childbearing age has inevitably led to a rise in the number of pregnancies in women who have had restrictive or malabsorptive procedures, with a consequent rise in the risk of maternal malnutrition.
