Sleep apnea is a potentially serious disorder in which a sleeper's breathing repeatedly stops and starts.
Now, a study presented to the American Thoracic Society's International Conference finds the severity of sleep apnea may be able to predict if you have diabetes.
Researchers followed almost 8,000 people and found that those with moderate to severe sleep apnea were also likely to have diabetes.
Low night-time levels of oxygen in the blood were also a predictor of diabetes, which is associated with a significant risk of cardio-vascular disease and death.
