As we all are aware, we have a growing epidemic of obesity and diabetes mellitus affecting not only adults but even our children.  One of the most interesting findings that are becoming available is the relationship between sleep deprivation and weight gain and diabetes.  A brain deprived of sleep does not utilize glucose as well as a well-rested brain.   Recent research suggests that untreated Obstructive Sleep Apnea (OSA) predisposes to insulin resistance, diabetes mellitus, visceral fat accumulation (the fat around our stomachs) and obesity.  Several studies have shown that OSA is independently associated with the development of insulin resistance and type 2 diabetes mellitus.  A study following habitual snorers over a period of 10 years showed that the snoring subjects were twice as likely to develop type 2 diabetes as non snorers.

What does OSA and/or sleep deprivation have to do with obesity?  Our bodies release two types of hormones related to eating.  One is called Leptin, which is the "stop you are full" hormone and the other is called as Ghrelin which is the "feed me" hormone.  The studies showed that when sleep deprived due to OSA, the subjects' bodies reacted by decreasing Leptin and releasing extra Gherlin.  Worse yet, the sleep deprived subjects not only displayed increased hunger but more often selected high carbohydrate candies, ice cream, pasta and bread when sleep deprived. Individuals when sleep deprived were less able to control their dietary urges and they experienced weight gain, particularly around their abdomens.

Many of these problems begin in childhood and the UNM SDC has the expertise to evaluate sleep in patients of all ages.  If you or a child you know snores, it is very important to get a referral to our sleep disorders center so we can determine if you or the child has OSA.
