Metabolic syndrome refers to the existence of at least three of five risk factors for heart disease, diabetes and stroke. Risk factors include: excess belly fat, high triglycerides, low HDL cholesterol, high blood pressure and high blood sugar.

Researchers from the University of Pittsburgh, United States studied 812 men, aged 45 to 74 years old, for three years. They found the risk of metabolic syndrome were more than two times higher in those with frequent loud snoring, 80 percent higher in those who have difficulty in sleeping, and 70 percent higher in those who sleep uncomfortably.

The findings, which was published December 1 in the Sleep journal, highlights sleep complaints in general. According to the study’s authors, Wendy M. Troxel, assistant professor of psychiatry and psychology at the University of Pittsburgh, this study is the first study that shows the types of commonly reported sleep disorder symptoms, including insomnia and sleep respiratory symptoms to predict the development of metabolic syndrome and its relation to heart disease. “It’s somewhat surprising that the effects of sleeplessness and snoring loudly are largely independent of one another,” said Troxel.

When the study focused on individual risk factors for metabolic syndrome, researchers found that loud snoring was significantly predicted to be a sign of high blood sugar and low HDL cholesterol levels.
