An eating disorder is characterized by an extreme disruption in regular eating habits, whether it is eating too little or eating too much. According to the National Institute of Mental Health, a person may start out eating less or more than usual, and then the habit spirals out of control. Someone with an eating disorder may also be overly concerned or distressed about weight or body shape.
Some types of eating disorders include anorexia nervosa, bulimia nervosa and binge eating disorder. Although eating disorders tend to manifest during teen years, they can also develop later in life. Both males and females are susceptible. It is not unusual for eating disorders to coexist with other anxiety disorders, depression or substance abuse. Eating disorders can be treated and are real illnesses. Although an eating disorder is a very serious condition, it is never too late to find treatment or learn how to help someone else.
