Sleep disorder during pregnancy may lead to gestational diabetes

A study has found that women who find they have developed a sleep disorder and are snoring loudly since falling pregnant may be at an increased risk of developing gestational diabetes.

The research was conducted at the Northwestern University Feinberg School of Medicine and was presented at the Sleep 2009 23rd annual meeting of the Associated Professional Sleep Societies today (June 11th).

Scientists revealed that women who started snoring regularly during pregnancy were more likely to develop the condition, while also discovering that being pregnant increased the chance a woman would start snoring.

Dr Francesca Facco, a fellow at Northwestern's Feinberg School, commented: "Snoring may be a sign of poor air flow and diminished oxygenation during sleep that can cause a cascade of events in your body.

"This may activate your sympathetic nervous system, so your blood pressure rises at night. This can also provoke inflammatory and metabolic changes, increasing the risk of diabetes or poor sugar tolerance."

She added that snoring could be prompted by weight gain associated with pregnancy and an accumulation of fluid causing resistance in the airways.
