Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects. A report of the study’s findings, published in the August issue of The Journal of Clinical Endocrinology & Metabolism, adds further support for the consistent use of continuous positive airway pressure (CPAP), a machine that increases air pressure in the throat to keep the airway open during sleep.
Jun emphasized that the study was limited by studying people with severe OSA and obesity, thus limiting the ability to apply the findings to all OSA patients. The researchers also did not compare CPAP use to a sham CPAP control group to exclude a potential placebo effect
Several studies have suggested that obstructive sleep apnea contributes to the development of left ventricular systolic and diastolic dysfunction and, possibly, heart failure. Note that this study indicates that moderate-to-severe sleep apnea can cause structural and functional changes in left ventricular function comparable to that seen in hypertension and, further, these abnormalities significantly improve following CPAP therapy.
A new study confirms that stroke patients who have moderate to severe obstructive sleep apnea (OSA) have a higher mortality risk than those without this condition and suggests that the successful use of continuous positive airway pressure (CPAP) therapy can reduce this excess risk.
