Women should wait at least 12 months before trying for a baby following weight loss surgery, suggests a new review paper in The Obstetrician & Gynecologist. The review looked at the safety, advantages and limitations of bariatric surgery and management of patients before, during and after pregnancy.
Obesity increases the risk of obstetric complications, however, pregnancy after bariatric surgery is safer than pregnancy in morbidly obese women, states the review. A previous study following pregnancies after weight loss surgery concluded that pregnancy is safe with 79 percent of participants having no complications during their pregnancy.
However, there can be surgical complications during pregnancy following bariatric surgery. A previous study found that band slippage and migration can occur, resulting in severe vomiting, and band leakage was reported in 24 percent of pregnancies.
The researchers recommend that patients should not get pregnant for at least 12 months following bariatric surgery. One study found a higher spontaneous miscarriage rate among pregnancies occurring within 18 months of having weight loss surgery compared with those pregnancies occurring more than 18 months after surgery (31 percent versus 18 percent).
"An increasing number of women of child-bearing age are undergoing bariatric surgery procedures and need information and guidance regarding reproductive issues. In light of current evidence available, pregnancy after bariatric surgery is safer, with fewer complications, than pregnancy in morbidly obese women. Multidisciplinary input care 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," concluded Rahat Khan, from the Princess Alexandra Hospital (UK) and co-author of the review.
