What is anorexia nervosa?

Anorexia nervosa, also known as anorexia nervosa, is an eating disorder. This disease makes you obsess about your weight and food. If you have this problem, your body image may be distorted. You may think you are fat even if your weight is very low.

When you have anorexia, you may use unusual eating habits to cope with stress, anxiety, and low self-esteem. Restricting food may give you a sense of control over your life.

This problem affects more women than men. It usually begins in adolescence. Since 1930, the number of young women aged 15 to 19 suffering from anorexia nervosa has increased every 10 years.

Experts don't know what causes anorexia. It usually starts with regular dieting. Over time, it can lead to extreme and unhealthy weight loss. Fear of gaining weight may lead you to resort to extreme dieting and food restriction techniques.

There are two subtypes of anorexia:

  • Restrictor type. People with this form of anorexia severely limit the amount of food they eat. This usually includes foods rich in carbohydrates and fats.
  • Types of bulimia (binge eating and binge eating). People with bulimia eat so much food that they vomit. They may take large amounts of laxatives or other methods to clear their bowels.

  • social attitudes
  • family influence

Focus on activities that have nothing to do with one's appearance.
