Investigation into other causes or exacerbating factors should be considered. For example, sleep-related breathing disorders, such as obstructive sleep apnea, are becoming increasingly relevant and novel risk factors for metabolic syndrome. [4]

The difficulty in clarifying the associations between obstructive sleep apnea and metabolic syndrome lie in part with the confounding effect of obesity. [83] Nevertheless, patients reporting significant sleep disturbances, snoring, possible pauses, and/or daytime drowsiness may benefit from further investigation for a treatable sleep-related breathing disorder, including through polysomnography.
