➤ Adequate, high-quality sleep is a key component of good health and is
fundamentally important in the treatment of obesity.
➤ Obstructive sleep apnea affects most patients with severe obesity and
requires systematic screening using validated tools and appropriate
referrals for sleep study evaluation.
➤ Disruptions in sleep and eating patterns are strongly associated with
obesity and can negatively affect metabolic and hormonal regulation.
Both insufficient sleep and night eating syndrome demonstrate a clear
link between these behaviors and increased weight.
➤ Poor sleep quality and duration affect brain regions involved in hunger
and satiety, such as the hypothalamus, leading to increased food
intake and weight gain.
➤ One night of sleep deprivation can alter the expression of several
genes, particularly those related to glucose tolerance. Sleep
deprivation also increases cortisol levels.
➤ Effective stress and sleep management are crucial for sustaining
weight management progress.
➤ One night of sleep deprivation increases ghrelin levels in addition to
cortisol levels. Leptin levels are also decreased after one night of sleep
deprivation. https://onlinelibrary.wiley.com/doi/full/10.1002/oby.23616
➤ Effect on Adiponectin remains unclear.
Assessment
Screening Tools to Evaluate for Possible Sleep Disorders
Epworth Sleepiness Scale
➤ Although primarily a monitoring tool, a score greater than 10 may
indicate excessive daytime sleepiness and warrant further evaluation.
Sleep Diary
➤ When logged for approximately two weeks, it may help screen for
circadian rhythm disorders; accelerometry is an alternative but is not
widely available.
STOP-BANG
➤ A score of three or more may indicate a higher risk of obstructive sleep
apnea.
Other Questionnaires
➤ Tools such as the Morningness-Eveningness Questionnaire, Munich
Chronotype Questionnaire, and Sleep Timing Questionnaire may be
used to assess circadian rhythm disorders, but are more commonly
used in research settings.
