What are the potential causes of night eating syndrome?
Night eating syndrome – an eating disorder characterized by nocturnal awakenings followed by food intake – is estimated to affect 1.5 percent of Americans, according to research in the journal Appetite. Despite the prevalence of the disorder, its etiology remains unknown. There are a variety of potential causes of night eating syndrome that could contribute to its development.
Psychological Causes
Psychological factors may be involved in the development of night eating syndrome. It is believed that people who suffer from depression, anxiety and other psychiatric disorders are predisposed to developing the condition. Individuals with night eating syndrome may also have difficulty dealing with stress. Additionally, certain personality traits—such as being compulsively organized and resistant to change—have been associated with the disorder.
Biological Causes
Research suggests that the onset of night eating syndrome is often influenced by biological factors. Specifically, hormonal imbalances are believed to play a role in its development. Abnormalities in cortisol – the hormone that regulates stress and sleep patterns – and ghrelin – the hormone that stimulates appetite – have been shown to be associated with night eating syndrome. Other possible biological causes include changes in melatonin, serotonin and leptin, neurotransmitters that control sleep, hunger and satiety.
Environmental Influences
Environmental factors may also contribute to the onset of night eating syndrome. Studies have indicated that this disorder is more prevalent in populations that engage in shift work, have out-of-sync circadian rhythms or live in an environment with unlimited access to food. Additionally, there is evidence that nighttime food cravings can be triggered by external cues in the environment, such as television commercials and late-night snacking.
Interrelated Causes
Since the etiology of night eating syndrome is unknown, a combination of causes may be involved in its development. For instance, psychological and environmental factors could interact to trigger night eating syndrome in an individual. Biological factors such as hormonal imbalances also could contribute to the disorder.
While the potential causes of night eating syndrome remain largely unknown, research indicates that psychological, biological and environmental influences likely play a role in its development. To diagnose night eating syndrome, individuals should consult a healthcare professional and discuss their history, signs and symptoms. View now
[What are the symptoms of night eating syndrome?
](
Night eating syndrome (NES) is a condition characterized by late-night binges and excess caloric intake. People with NES typically experience cravings for food late in the evening, beginning after dinner and continuing until morning. These cravings often prompt people with NES to eat large amounts of high-calorie, sweet, and/or starchy foods. This can lead to weight gain and related health issues.
NES is closely associated with a number of other conditions, such as depression, anxiety, obsessive-compulsive disorder, substance use disorder, and binge eating disorder. It is also linked to an increased risk of developing type 2 diabetes, metabolic syndrome, and cardiovascular disease.
Common symptoms of night eating syndrome include:
• Eating the majority of their daily caloric intake after dinner.
• Feeling out of control or unable to stop eating during late-night binging episodes.
• Feeling too full after eating, but still craving foods late at night.
• Having difficulty sleeping or waking throughout the night due to hunger or cravings.
• Feeling irritable, anxious, or depressed when not able to access food late at night.
• Eating most of their meals during the evening or overnight hours.
• Eating very little during the day or skipping meals altogether.
• Experiencing guilt or shame related to their nighttime eating habits.
• Experiencing unusual levels of hunger during the day, leading to overeating during the night.
Intervention is key for people with night eating syndrome; seek the help of a healthcare professional to determine whether NES is causing weight gain or health-related issues and to develop a plan for treatment and management. Treatment may include talk therapy, medications, lifestyle changes, and dietary modifications. It is also important to identify and address any underlying conditions or mental health issues that may be related to the eating disorder. Professional help can enable an individual to learn how to establish regular eating patterns and develop healthier dietary behaviors.
