The link between being
overweight and an increased risk for developing obstructive sleep
apnea (OSA) have long been known, but a recent study indicates that losing
weight—particularly belly fat—can help you sleep better and may even reduce
instances of apnea in those with OSA.
Researchers from the
Johns Hopkins School of Medicine recently studied 77 overweight volunteers,
many of whom suffered sleep
disorders including sleep apnea. The volunteers were split into two groups,
one of which engaged in a weight-loss plan that included dietary changes and
supervised exercise while the other group followed only the diet.
Overall, the participants
from both groups lost an average of 15 pounds over six months and reduced belly
fat by 15 percent. According to the study, the findings of which were presented
at the annual meeting of the American Heart Association, belly fat reduction
was the best predictor of improved sleep, and patients with OSA reported fewer
instances of interrupted breathing during sleep.
Although the study did
not determine why reducing belly fat seems to be a key to improved sleep, the
particular type of fat that accumulates around the abdomen—which is also known
as visceral fat—has been linked to an increased risk for OSA, heart disease,
diabetes, certain cancers and other health problems. Sleep apnea, in turn, can
increase a person’s risk for conditions including high blood pressure and
stroke.
If you or your partner
suffers from loud, chronic snoring or other symptoms of sleep
apnea, it’s important to undergo an evaluation as soon as possible.
Although OSA is a potentially life-threatening condition, there are also a
number of effective treatment options available through the field of dental
sleep medicine.
