A study of 189 healthy, pregnant women found those who snored more than 3 times a week had a 14-percent chance of developing gestational diabetes. Those who didn't snore had a 3.3-percent chance of developing the condition -- which is when women who don't have already have diabetes develop high blood sugar levels during pregnancy.
It goes away after the baby is born, though it leaves women at risk for Type II diabetes.
The link between snoring and gestational diabetes isn't clear. Researchers say poor air flow might lead to metabolic changes that would increase the risk for poor sugar tolerance.
