Obesity is a global pandemic with far reaching implications. The overall
trend of Americans who are classified as obese and morbidly obese continues to rise.
Alongside, the cost of healthcare as it relates to obesity and obesity-related illness
continues to rise, in fact, it has doubled over the past 10 years. Obesity-related illnesses
include type 2 diabetes, cardiovascular diseases, chronic kidney disease, and chronic
liver disease among others. Paralleling the obesity epidemic, sleep loss and dysfunction
have emerged as a public health issue. Both obesity and sleep dysfunction share
important pathophysiologic pathways, resulting in a persistent low-grade inflammatory
state which ultimately contributes to chronic disease as part of the metabolic syndrome.
This chapter outlines the role of sleep in the pathogenesis of obesity and reviews the
potential therapeutic implications of restoring normal sleep function in patients with
obesity and obesity-associated diseases.
