Be careful, surgery makes pregnancy difficult

To treat obesity, bariatric surgery is on the rise, but it is not without risk. According to a new study, women who have had surgery have a more complicated pregnancy than average, with a risk to the unborn child.

Congenital abnormalities

The researchers compared over 14,800 pregnancies to obese women who were operated on for nearly 4 million normal pregnancies. The results showed that children born after bariatric surgery were 57% more likely to be premature, 29% more likely to have congenital abnormalities and 41% more likely to be admitted to the neonatal intensive care unit. In addition, children born after obesity surgery had a 38% higher risk of death within seven days of birth and were lighter than others.

"Our results show that women with a history of bariatric surgery, especially bypass surgery, are much more exposed," says Zainab Akhter, research director. "These women need specific nutritional support before onset and pregnancy, and our results emphasize the importance of food supplements and monitoring fetal growth and development." and advice to provide the right advice, ”he says.

Women prevail in traffic

In France, obesity affects 15.8% of men and 15.6% of women. As a result, the use rate of bariatric surgery increased by a factor of 2.6 between 2008 and 2014. In 2014, 45,474 patients received bariatric surgery, of which 65.6% were morbidly obese. , with predominantly operated women, younger than men. Bariatric surgery aims to change the way food is absorbed by the digestive system and includes three major operations: gastric bypass, sleeve gastrectomy, and gastric banding.

"We don't know exactly how bariatric surgery can affect fetal development, but we know that people who suffer from this disease are more likely to have micronutrients," Akhter says.
