Patients suffering from Type-2 diabetes and hypertension are at much higher risk for OSA, as shown by overwhelming clinical evidence, Research also indicated that treating OSA could help manage these 2 disorders, including improved insulin sensitivity, blood pressure and cholesterol.
As revealed by Centers for Disease Control and Prevention (CDC), 25.6 million Americans aged 20 years or older suffer from diabetes. 90 to 95 percent of these patients are Type-2 diabetics. 7 in 10 people with Type-2 diabetes also have OSA, and it was found that the severity of the sleep disorder directly affects the glucose control.
Treating sleep apnea in diabetics could not only lower their nighttime glucose levels and insulin sensitivity but also provide them with benefits of improved sleep unrelated to diabetes, including better alertness during the day and improved memory as well as cognitive function.
According to a recent study by the University of Chicago, continuous positive airway pressure (CPAP) treatment of sleep apnea might have an effect comparable to prescribed oral diabetes medications.
In the study, average 24-hour glucose levels were reduced and post-breakfast glucose response was improved in Type-2 diabetics with OSA, with just one week of optimal CPAP. CPAP therapy also reduced dawn phenomenon, an early-morning surge in blood sugar in people with Type-2 diabetes, by 45 percent.
About 67 million Americans have hypertension, or 1 in every 3 adults. 30 to 40 percent of these patients also have sleep apnea. Approximately 80 percent of those who do not respond to hypertensive drugs have sleep apnea.
The nighttime and daytime blood pressure will decline with appropriate sleep apnea treatment. For patients with moderate to severe sleep apnea, the treatment would give them the greatest improvement. Reducing blood pressure would naturally lower the risk of cardiovascular disease and improve the overall health.
