It may be regarded as an eating disorder.This term may also be used to refer to specific episodes of over-consumption. For example, many people overeat during festivities or while on holiday.Overeating can sometimes be a symptom of binge eating disorder or bulimia.Compulsive over eaters depend on food to comfort themselves when they are stressed, suffering bouts of depression, and have feelings of helplessness.In a broader sense, hyperalimentation includes excessive food administration through other means than eating, e.g. through parenteral nutrition.
