Nighttime binge eating syndrome

This disorder is characterized by episodes of overeating at night, while very little or no food is consumed during the day. More than 25% of daily caloric intake is often ingested after dinner and during the night, which can disrupt sleep and cause insomnia. This syndrome is frequently associated with a deterioration in mood, particularly in the evening, as well as anxiety. The probable origins of this behavior are associated with genetic and hormonal factors.
