In contrast to the widespread issue of being overweight, a significant minority of the population suffers from eating disorders, which commonly lead to being underweight. These conditions, such as bulimia nervosa and anorexia nervosa, are often characterized by an intense fear of gaining weight and can result in numerous negative health effects.

Eating Disorders 

Bulimia nervosa is an eating disorder characterized by a cycle of binge eating followed by compensatory actions. Individuals consume abnormally large amounts of food and then attempt to offset this intake through behaviors such as purging or excessive exercising.

Bulimia Nervosa

Binge eating disorder is a psychological condition involving eating binges that are not accompanied by inappropriate compensatory behaviors, such as purging. Instead, these episodes are followed by significant distress, including feelings of guilt and embarrassment, which serves to distinguish the disorder from standard overeating.

Rumination disorder is an eating disorder where an individual unconsciously regurgitates food immediately after eating. This eating disorder is rare and is most common in children.

Rumination Disorder

A disorder commonly found in children, ARFID can be described as extremely picky eating, though fear foods differ significantly from those with anorexia nervosa and bulimia nervosa. Although ARFID involves food restriction and thus shares some features with anorexia nervosa, the fear and restriction surrounding food is not due to concerns about weight or body image.
