Avoid Pregnancy for a Year After Weight-Loss Surgery: Review01/11/13
FRIDAY, Jan. 11 (HealthDay News) -- Women should wait at least
one year after having weight-loss surgery before they try to get
pregnant, researchers say.
The obesity rate among women of child-bearing age is expected to
rise from about 24 percent in 2005 to about 28 percent in 2015, and
the number of women having weight-loss surgery is increasing, the

In light of current evidence available, pregnancy after bariatric surgery is safer, with fewer complications, than pregnancy in morbidly obese women," review co-author Rahat Khan, a consultant obstetrician and gynecologist at Princess Alexandra Hospital NHS Trust in Harlow, England, said in a journal news release.
Guidance from a variety of health care specialists "is the key
to a healthy pregnancy for women who have undergone bariatric
surgery. However, this group of women should still be considered
high risk by both obstetricians and surgeons," Khan added.
