Loud Snoring and Insomnia Symptoms May Lead to Metabolic Syndrome

The development of obesity-related risk factors starts with a series of common sleep problems, a new study reports. People who snore loudly or have two common insomnia symptoms – difficulty falling asleep and unrefreshing sleep - have an increased risk of developing metabolic syndrome.

Metabolic syndrome increases the risk of heart disease, diabetes and stroke. People with metabolic syndrome must have at least three out of the five following risk factors: excess abdominal fat, high triglycerides, low HDL cholesterol, high blood pressure and high blood sugar.

Findings show people who snore have double the risk of developing metabolic syndrome doubles. Specifically, loud snoring predicts the development of high blood sugar and low HDL cholesterol.

The risk also increases by 80 percent in adults who have difficulty falling asleep and by 70 percent for people who don’t feel refreshed after waking. However, neither risk was tied to a specific risk factor.

Two other common insomnia symptoms - difficulty staying asleep and frequent waking - did not predict the development of metabolic syndrome.
