Weight-loss surgeries lead to other changes besides the actual loss of the weight. Scientists from Sweden have discovered that women are less prone to diabetes after such an intervention. In addition, pregnancies suffer a lot of complications, such as the possibility that women deliver a baby that is smaller than normal infants.
Bariatric surgeries have different effects on women before they get pregnant – some of them are for the better and some are for the worse. A pregnancy that is being found after an intervention of weight loss must be highly monitored and paid attention to, more than in other cases where such surgeries haven’t been present. The study has been published online in the 26th of February, in the New England Journal of Medicine.
Study author Kari Johansson, a postdoctoral researcher and nutritionist at Karolinska Institute in Stockholm believes that the number of women who are obese at the beginning of their pregnancy has increased very much over the last decades, and also there are more and more women that want to become pregnant after a bariatric surgery and they actually do so.
“The positive effects of bariatric surgery on health outcomes — such as diabetes and cardiovascular disease — are reasonably well-studied, but less is known about the effects on pregnancy and [post-delivery] outcomes.”
Taking into consideration the official facts that say that one-third of American adults are obese with a body mass index of 30 or more, the rate of those who want to have a surgery grows stronger. In 2013, the United States alone have gathered 179,000 obese people that have tried this particular surgery, the American Society for Metabolic and Bariatric Surgery says. The method is actually simple: the amount of food that the stomach can hold is restricted or it reduces the intestines’ absorption of calories and nutrients from food.
Comparing women having the same BMI but were different because some of them, about 600, have had the surgery before birth, and the rest of 2,300 women haven’t had surgery in these conditions. The number of patients that had developed gestational diabetes has been considerably smaller than the one of those who didn’t: 2 percent as compared to 7 percent. In addition, the study found that the women who have suffered the surgery have experienced a slight bump in the rate of stillbirths. This particularity and the one related to smaller babies haven’t been proved 100% to be caused by the surgery, but it might happen because of the reduced nutrient absorption that is actually a downside of the surgery.
