Binge-eating disorder

Overview


Plain-Language Overview

Binge-eating disorder is a condition that affects the way people eat and their relationship with food. It involves episodes of eating a very large amount of food in a short period, often feeling out of control during these episodes. This disorder primarily impacts the digestive system and can lead to significant weight gain and related health problems like diabetes and heart disease. People with this disorder may feel shame or distress about their eating habits, which can affect their mental health. It is different from simply overeating because it happens repeatedly and is associated with a loss of control.

Clinical Definition

Binge-eating disorder is characterized by recurrent episodes of consuming an excessive amount of food within a discrete period, accompanied by a sense of loss of control over eating. The core pathology involves dysregulation of appetite and satiety signals, often linked to psychological stressors and neurobiological factors affecting reward pathways. Unlike bulimia nervosa, these episodes are not followed by compensatory behaviors such as purging. The disorder is associated with significant psychological distress, obesity, and increased risk of metabolic syndrome. It is the most common eating disorder and has a complex etiology involving genetic, environmental, and neurochemical components. Recognition and diagnosis are critical due to its impact on both mental and physical health.
