individuals?

   People with this condition are       NES individuals had lower
    under stress, either recognized       nighttime serum melatonin.
    or hidden.
   Their bodies are flooded with        Smaller nighttime rise in Leptin.
    Cortisol, a stress hormone.
                                         Plain and simple: Their bodies

                        Hormones
   Leptin falls in response to fasting or weight loss.
   Ghrelin increases before meals in normal subjects and is
    suppressed by feeding.
   Melatonin peaks during the first half of the night.
   Cortisol and prolactin are both increased by stress
   Cortisol peaks in the morning while prolactin peaks during the
    latter part of the sleep period and declines upon awakening.
   Thyroid stimulating hormone (TSH) peaks in the late evening
    and is suppressed by sleep.
Hormones Activity in NES Subjects

   Insulin was higher at night and lower in the morning for NES subjects.
   Ghrelin levels showed a pattern opposite of that of insulin, lower in the
    early morning hours.
   Leptin and melatonin levels increased at night in NES subjects.
   Cortisol was highest in the morning and declined at night.
   There was a trend for TSH levels to be higher in NES subjects than in
    controls, especially in the early morning.
Average Caloric Intake
Treatment Options

   Sertaline

   Stress-reduction programs, including mental health
    therapy, seem to help
