354 Feeding and Eating Disorders
5.Night eating syndrome:  Recurrent episodes of night eating, as manifested by eating
after awakening from sleep or by excessive food consumption after the evening meal.
There is awareness and recall of the eating. The night eating is not better explained by
external influences such as changes in the individual’s sleep-wake cycle or by local so-
cial norms. The night eating causes significant distress and/or impairment in function-
ing. The disordered pattern of eating is not better explained by binge-eating disorder
or another mental disorder, including substance use, and is not attributable to another
medical disorder or to an effect of medication.
Unspecified Feeding or Eating Disorder
307.50 (F50.9)
This category applies to presentations in which symptoms characteristic of a feeding and
eating disorder that cause clinically significant distress or impairment in social, occupation-
al, or other important areas of functioning predominate but do not meet the full criteria for
any of the disorders in the feeding and eating disorders diagnostic class. The unspecified
feeding or eating disorder category is used in situations in which the clinician chooses not
to specify the reason that the criteria are not met for a specific feeding and eating disorder,
and includes presentations in which there is insufficient information to make a more spe-
cific diagnosis (e.g., in emergency room settings).
