WEDNESDAY, June 13 (HealthDay News) — People with diabetes are
at increased risk for obstructive sleep apnea, which appears to boost
their craving for carbohydrates, a new study suggests.
Because unrestricted carbohydrates can harm someone with diabetes, the
findings point to the need for primary care doctors to screen for
obstructive sleep apnea in patients with type 2 diabetes, the study
authors said.
The researchers checked 55 people for diabetes, obstructive sleep apnea
and carbohydrate cravings, and found that more than half of them had
diabetes. Eighty-two percent of the diabetic patients had obstructive
sleep apnea, and diabetic patients had nearly double the risk of
carbohydrate cravings as those without diabetes.
The investigators also found that patients with sleep apnea were nearly
twice as likely to have high carbohydrate cravings as patients without the
sleep disorder.
Obstructive sleep apnea occurs when the tissue in the back of the
throat blocks the airway, which causes people to stop breathing while they
are sleeping. The condition disrupts sleep and can cause daytime fatigue,
and increases the risk of other health problems such as heart disease and
stroke.
The study was scheduled for presentation Wednesday at the annual
meeting of the Associated Professional Sleep Societies in Boston.
The findings offer an indication of the degree that sleep apnea can
affect carbohydrate craving in people with diabetes, said study
co-investigator Dr. Mahmood Siddique, clinical associate professor of
medicine at the Robert Wood Johnson Medical School in New Brunswick,
N.J.
“Previous studies have shown that sleep deprivation may lead to changes
in hormones that regulate appetite and hunger,” Siddique said in a news
release from the American Academy of Sleep Medicine. “These hormonal
changes can lead to significant craving for high-calorie carbohydrates
such as cookies, candy, breads, rice and potatoes. The current study
supports previous findings by validating this in a community sample of
diabetics.”
People with diabetes have excess blood sugar. Because carbohydrates
break down into sugar in the body, they have the greatest impact of all
the food groups on blood glucose level. Carbohydrates found in fresh fruit
and whole grains are generally safer for patients with diabetes than
sugary carbs.
An East Coast expert said doctors should be alert for sleep apnea among
their diabetic patients. “Current national guidelines on the management of
diabetes need to consider sleep apnea as an independent risk factor more
vigorously,” study principal investigator Dr. Anthony Cannon said in the
news release.
“The management of patients with diabetes and or metabolic syndrome
based solely on [drug therapy], exercise and nutritional modifications
without taking into account the risk of sleep apnea may not lead to
optimal outcomes for patients suffering from these chronic diseases,”
added Cannon, the American Diabetes Association regional president for
central and southern Pennsylvania and southern New Jersey.
Cannon added that sleep apnea is often undiagnosed by primary care
physicians. “Public policy can play a key role in the educational
awareness of the association between sleep apnea and diabetes among both
physicians and patients,” he concluded.
While the study uncovered an association between sleep apnea and carb
cravings in diabetics, it did not prove a cause-and-effect
relationship.
Data and conclusions of research presented at meetings should be
considered preliminary until published in a peer-reviewed medical
journal.
