The Differences Between Anorexia And Bulimia

The distinctions between eating disorders can be confusing. While anorexia and bulimia may have some issues in common, other factors make them distinct. For parents, understanding the differences can be crucial, as early detection and proper treatment significantly improve the chances a child will recover. Following is information to help distinguish between the two.

Definition:
Anorexia is more common in teenagers, while bulimia is more often seen in women in their 20's. However, don't make the mistake of thinking there is a set age for either of these diseases. Here are differences between anorexia and bulimia based on the American Psychiatric Association's definition:

Bulimia Nervosa
• Recurrent episodes of binge eating (minimum average of two binge-eating episodes a week for at least three months).
• A feeling of lack of control over eating during the binges.
• Regular use of one or more of the following to prevent weight gain: self-induced vomiting, use of laxatives or diuretics, strict dieting or fasting, or vigorous exercise.
• Persistent over-concern with body shape and weight.

Anorexia Nervosa
• Refusal to maintain weight that's over the lowest weight considered normal for age and height.
• Intense fear of gaining weight or becoming fat, even though underweight.
• Distorted body image.
• In women, three consecutive missed menstrual periods without pregnancy.

Signs & Symptoms:
While both disorders focus on an obsession with thinness, anorexics display noticeable, often severe weight loss while bulimics usually maintain a healthy weight. Here are other signs and symptoms of these two eating disorders:
