Here's a wake-up call to the millions of American men and women with Type 2 diabetes: Snoring at night or nodding off during the day may be symptoms of obstructive sleep apnea, a potentially life-threatening problem affecting one out of three diabetics.

Based on strong preliminary evidence linking the two disorders, global health experts are encouraging physicians to assess their diabetic patients for sleep apnea symptoms and to screen sleep apnea sufferers for metabolic disease. The recommendation comes from the International Diabetes Federation (IDF) Task Force on Epidemiology and Prevention.

"It is probably too early to see any concrete evidence of changes in practice, but there is little doubt that awareness of the importance of screening people with diabetes and people with sleep apnea for the other condition is rising," says Dr. Jonathan Shaw, lead author of the IDF task force consensus statement.

Sleep apnea occurs when a person's airway becomes blocked during sleep. It's usually caused by the collapse of soft tissue in the back of the throat during sleep. Between snores, breathing stops for a period of 10 seconds or longer, and this pattern repeats itself multiples times over the course of a night.

Not only does it deprive the person of a good night's sleep, but it may increase the risk for high blood pressure and heart disease, according to the IDF.

Obstructive sleep apnea affects just 2% of women and 4% of men in the general population. But it's much more prevalent among diabetics.

In a recent report in the journal Endocrine Practice, researchers examined data from 279 men and woman with Type 2 diabetes. Overall, 36% had obstructive sleep apnea.

Men with diabetes were particularly vulnerable. Below age 45, they had more than a one-third increased chance of developing sleep apnea, and that risk doubled above age 65. For women below 45, the chances of having sleep apnea were slim: between 5% and 8%. Females 65 and older, however, had a one-third increased chance of having the sleep disorder, the study found.

Interestingly, being heavier or taking more medicines were not predictors of sleep apnea. The only correlations were age and gender.

"It suggests that once you're diabetic, there's such a powerful disposition to obstructive sleep apnea that the other contributing variables are simply less important," says Dr. Daniel Einhorn, a medical director at the Scripps Whittier Institute for Diabetes in La Jolla, Calif.

Diagnosing sleep apnea is critical, he noted, because treating the sleep disorder can make a huge difference in the patient's diabetes. "Successful treatment of sleep apnea has a greater impact to improve blood sugar than any single thing you can do in a diabetic," Einhorn says.
