CPAP use improves blood sugar and glucose variability in sleep apnea patients: Study

The results of the study are as follows:

• Among 42 patients with obstructive sleep apnea syndrome (OSA) and no diabetes, the standard deviation of Glucose variability (GV) during sleep correlated significantly with sleep time spent with oxygen saturation <90%
• High blood glucose index during sleep correlated significantly with stage N1% and negatively with stage N2%
• High blood glucose index correlated significantly with sleep time spent with oxygen saturation <90%
• The rapid eye movement-related obstructive sleep apnea syndrome (OSA) group had a higher incidence of hypoglycemia.
• One-week with CPAP treatment significantly improved Glucose variability (GV) during sleep, the standard deviation of Glucose variability (GV), and high blood glucose index.

As their findings suggested greater Glucose variability (GV) during sleep in patients with obstructive sleep apnea syndrome (OSA) and normal glucose tolerance, compared with healthy individuals. The researchers concluded that it is essential to evaluate Glucose variability (GV) during sleep in patients with obstructive sleep apnea syndrome (OSA) may be useful for clinical risk management. Also, CPAP treatment for 1 week may have an improving Glucose variability (GV) and high blood sugar index.
