Night eating syndrome
Night eating syndrome (NES) is an eating disorder, characterized by a delayed circadian pattern of food intake. Although there is some degree of comorbidity with binge eating disorder, it differs from binge eating in that the amount of food consumed in the evening/night is not necessarily objectively large nor is a loss of control over food intake required. It was originally described by Dr. Albert Stunkard in 1955  and is currently included in the “Other Specified Feeding or Eating Disorder” category of the DSM-5. Research diagnostic criteria have been proposed and include evening hyperphagia (consumption of 25% or more of the total daily calories after the evening meal) and/or nocturnal awakening and ingestion of food two or more times per week. The person must have awareness of the night eating to differentiate it from the parasomnia sleep-related eating disorder (SRED). Three of five associated symptoms must also be present: lack of morning hunger, urges to eat in the evening/at night, belief that one must eat in order to fall back to sleep at night, depressed mood, and/or difficulty sleeping. NES affects both men and women, between 1 and 2% of the general population, and approximately 10% of obese individuals. The age of onset is typically in early adulthood (spanning from late teenage years to late twenties) and is often long-lasting, with children rarely reporting NES. People with NES have been shown to have higher scores for depression and low self-esteem, and it has been demonstrated that nocturnal levels of the hormones melatonin and leptin are decreased. The relationship between NES and the parasomnia SRED is in need of further clarification. There is debate as to whether these should be viewed as separate diseases, or part of a continuum.
NES is sometimes associated with excess weight; as many as 28% of individuals seeking gastric bypass surgery were found to suffer from NES in one study. However, not all individuals with NES are overweight. Night eating has been associated with diabetic complications. Many people with NES also experience depressed mood  and anxiety disorders. through certain medication's can create a more substantial amount of hunger in one, that in itself should not awaken someone. unless pain itself wakes you up and along the way of the medication fully functioning, instead of falling back asleep, instead hunger is felt. this would only happen to a certain percentage of people though and is not the case in all, or for all individuals. another symptom that could portray itself as just N.E.S or N.E.S with diabetes is awaking with a pins and needles sensation in your extremities. as for mentioned previously, also the thought you cannot go back to sleep without the need of having some kind of food (or) nutrition in you first. Generally in, Night Eating Syndromes. The specific food you awaken for, or are wanting after a shortened period of "rest", is generally going to be of carbohydrates or fats/sweets. nothing very nutritionally beneficial to yourself or another. as a last note, if complications develop or new symptoms become persistent. consult your general practitioner or pediatrician. many syndromes or diseases can mimic Night Eating Syndrome / Night Disorders. Never rely on an article as a definitive diagnosis. Your doctor is more likely to order tests, before forming a firm diagnosis. be sure to share all things, that might be feeling slightly off in you. Even what might seem as insignificant to you, might remain as highly significant or beneficial to your or your child's doctor. sometimes maintaining a timed and dated log may help.
