Causes and Symptoms

⏳ Reading time: 5 minutes

Sleep-related eating disorder (SRED) is a type of parasomnia condition characterized by recurrent episodes of involuntary eating during sleep. Unlike typical nocturnal snacking, SRED involves eating large amounts of food unconsciously, often leading to weight gain, sleep problems, and other health concerns.

This disorder is closely related to other sleep disorders, such as night eating syndrome (NES) and sleepwalking.

Causes of Sleep-Related Eating Disorder

The exact cause of SRED is not fully understood, but several factors are believed to contribute to its development:

Sleep Disorders: SRED often co-occurs with other sleep disorders, including obstructive sleep apnea and restless legs syndrome. These conditions may disrupt the sleep-wake cycle, triggering unusual eating behaviors during slow-wave sleep.
Genetics and Family History: A family history of parasomnias or other sleep disorders increases the risk of developing SRED. This suggests a potential genetic predisposition to the disorder.

3. Mental Health Conditions: Individuals with mood disorders, such as depression and anxiety, or other mental health conditions are at a higher risk of experiencing SRED episodes. According to the Cleveland Clinic, stress and emotional distress can exacerbate these behaviors.

4. Medications: Certain medications, particularly those affecting the brain's neurotransmitters, like selective serotonin reuptake inhibitors (SSRIs), have been linked to the onset of SRED. These medications can alter brain activity during sleep, leading to sleep-eating events.

5. Substance Abuse: A history of drug abuse or alcohol consumption is another risk factor. Toxic substances can interfere with normal sleep patterns and may trigger sleep-related eating disorder attacks.

Symptoms of Sleep-Related Eating Disorder

SRED manifests through several distinct symptoms:

Involuntary Eating During Sleep: SRED patients typically engage in recurrent episodes of involuntary eating, often consuming large amounts of food, including unusual or non-food items.

These sleep-eating episodes usually occur during the middle of the night and are followed by little to no memory of the event the next morning.
Frequent Sleep Interruptions: People with SRED often experience frequent sleep interruptions due to their nocturnal eating behavior. This can lead to sleep deprivation and a decrease in overall sleep quality.
Unusual Eating Behaviors: During SRED episodes, individuals might consume bizarre combinations of food or even toxic substances like cleaning products or raw meat. This poses a significant risk to their health.
Weight Gain and Health Issues: The excessive food intake during sleep can lead to weight gain and increase the risk of obesity, type 2 diabetes, and other related health problems. The consumption of large amounts of food, particularly high-calorie items like peanut butter, further exacerbates these issues.
Embarrassment and Shame: SRED can cause significant emotional distress. Individuals may feel embarrassed or ashamed of their behavior, leading to a decline in their quality of life and exacerbation of mood disorders.

Diagnosis and Treatment

Diagnosing SRED typically involves a comprehensive evaluation by a sleep specialist, which may include a sleep study to monitor brain activity and sleep patterns.

A sleep diary might also be recommended to track sleep habits and food intake.

Treatment options vary depending on the underlying causes and severity of the disorder:

Cognitive Behavioral Therapy (CBT): CBT is a common treatment for SRED, focusing on identifying and changing harmful thoughts and behaviors related to sleep and eating. According to Healthline.com, CBT can be particularly effective in managing sleep-related eating behaviors.
Medications: While medication should be used cautiously, some drugs can help manage SRED symptoms. However, sleeping pills are generally avoided as they can worsen confusion and clumsiness during SRED episodes.
Lifestyle Changes: Adjusting sleep habits, reducing stress, and avoiding triggers like alcohol and caffeine can significantly reduce SRED episodes. Maintaining a regular sleep-wake cycle and engaging in relaxation techniques before bed can also help.
Addressing Co-occurring Disorders: Treating underlying sleep disorders, such as obstructive sleep apnea or restless legs syndrome, can help reduce the frequency of SRED episodes.

Sleep-related eating disorder is a complex condition that can significantly impact an individual's health and quality of life. Understanding the causes, symptoms, and treatment options is crucial for managing the disorder effectively.

If you or a family member is experiencing unusual eating behaviors during sleep, it’s important to consult a sleep expert for a thorough evaluation and appropriate treatment.
