A recent study found that the birth of a child with large congenital malformations is more likely if the mother is obese at the time of conception.
Medical research has long linked obesity to increased odds of pregnancy complications for both mothers and fetuses. Recently, a recent Swedish study found that the level of obesity among pregnant women is linked to an increased risk of birth defects.
The study analyzed 1,200,000 births in Sweden and found that the risk of health problems such as congenital heart defects, neurological function and limb abnormalities increased according to the level of maternal obesity at the beginning of pregnancy.
Obese pregnant women increase the risk of congenital malformations at birth
The risk of serious congenital defects in women with normal weight was 3.4 percent, while among obese mothers it was 3.8 to 4.7 percent.
The sensitive stage of fetal growth is the first eight weeks. During this stage, the mother’s BMI plays a negative role, which means that it is important to try to maintain the weight closest to normal before pregnancy.
The study confirms previous research that linked birth defects to obesity, and provides a new look at how the amount of extra weight in a mother affects a child’s risk of health problems, said the head of obstetrics and gynecology at the University of Oregon Health and Science in Portland, That lowering the mother’s weight before giving birth reduces the likelihood of complications even if you can not reduce the weight before pregnancy to the normal level.
He added that all women should start pregnancy with a normal weight, and if not, the adoption of a healthy diet and exercise regularly is very important.
