10 Differences Between anorexia nervosa and bulimia nervosa

What is Anorexia Nervosa?

Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight and a distorted body image. Individuals with anorexia nervosa often restrict their food intake, resulting in significant weight loss. It is a serious psychological condition that can lead to severe health complications if left untreated.

Examples of Anorexia Nervosa:

1. Refusal to maintain a healthy body weight.
2. Intense fear of gaining weight or becoming fat.
3. Distorted perception of body shape or size.
4. Excessive exercise or activity to burn calories.
5. Self-imposed restrictive eating habits.

What is Bulimia Nervosa?

Bulimia nervosa is an eating disorder characterized by recurring episodes of binge eating followed by compensatory behaviors such as purging, excessive exercise, or fasting. People with bulimia nervosa often feel a loss of control during binge episodes and are driven by a strong desire to prevent weight gain.

Examples of Bulimia Nervosa:

1. Regular episodes of binge eating.
2. Feeling out of control during binge episodes.
3. Purging through vomiting, use of laxatives, or diuretics.
4. Excessive use of exercise as a form of compensatory behavior.
5. Frequent and secretive food hoarding.
