Thirty\u2010nine of these women (with an average age of 31 \u00b1 4.8\u2009years) became pregnant (one twin pregnancy) and 29 of the 39 had undergone a gastric bypass. The mean time interval between BS and pregnancy was 16.6 \u00b1 4.8\u2009months; however, 16 (41%) women became pregnant less than a year after BS.

Three women developed gestational diabetes mellitus. Premature rupture of membranes occurred in two pregnancies, preterm delivery in five, and there was one spontaneous abortion. Cesarean section was performed in seven cases. The average newborn weight was 3002 \u00b1 587\u2009g, five were small for gestational age, and one had macrosomia.
