Night Eating Syndrome

Definition of night eating syndrome

Night eating syndrome (NES) is a syndrome of excessive eating and sleeping problems. Patients may eat a lot after dinner, causing difficulty sleeping, and may get up to continue eating because they cannot sleep. It should be noted that night eating syndrome is different from binge eating disorder (also known as bulimia).

People with narcolepsy eat large amounts in one sitting, while people with nocturnal eating syndrome eat small but continuous meals at night. Night eating syndrome is also different from other sleep-related eating disorders because people with night eating syndrome often remember what they eat.

How common is night eating syndrome?

Approximately 1 in 100 people suffer from night eating syndrome. Among obese people, 1 in 10 people suffer from this disease. For information on ways to reduce the risk of this disease, please consult your physician.

Symptoms of night eating syndrome

Patients with night eating syndrome will eat a portion of food equivalent to 1/4 of the total daily calories after dinner and feel troubled by this.

Diagnosis and treatment of night eating syndrome

The following information is not a medical diagnosis. For further information, please consult a physician.

How to Diagnose Night Eating Syndrome

The doctor will first ask the patient about his sleeping and eating habits, or ask the patient to fill in a questionnaire. Patients may also undergo multiple polysomnography tests to measure brain waves, blood oxygen concentration, and breathing and heartbeat rates. A patient must have overreacted at least three times within a month to be considered suffering from night eating syndrome. However, if the patient’s sleeping and eating problems are caused by substance abuse or other medical or psychological problems, they are not considered to have this disease.
