What are anorexia and anorexia nervosa?
People with anorexia nervosa try to keep their weight as low as possible by not eating enough food, exercising too much, or both. This can cause serious health problems due to malnutrition.
People with anorexia nervosa are often afraid of gaining weight and have distorted body images, thinking they are fat even if they are underweight. Men and women of any age can get anorexia, but it's most common in young women and typically starts in the mid-teens.
The difference between the two mostly comes down to how the term “anorexia” is used.

Causes of anorexia nervosa
The cause of anorexia nervosa is not well understood. Researchers think that eating disorders may come from a combination of a person’s biology and life experiences. Potential factors may include:

- Cultural pressures to be thin from pop culture and media

- Occupations that demand a thin physique, such as ballet or the fashion industry

Anorexia nervosa treatment
Anorexia nervosa is usually treated with a combination of psychotherapy, support, education, medication, and medical and nutritional counseling.
Supportive psychotherapy and clinical management can help the person recognize their distorted beliefs about their body image. Cognitive behavior therapy can also help a person recognize unhealthy thoughts about body image, food, and dieting.
Medications like antidepressants and antipsychotics have also been prescribed for people with anorexia nervosa to reduce psychological distress.
A trained nutritionist can also plan a healthy eating program that promotes slow weight gain.
