The diagnosis and evaluation process usually begins with a detailed interview with the person with anorexia nervosa and family members. Questions are usually asked about:
- Weight history
- Eating patterns
- Concerns about weight and shape
- Dieting and weight-losing behaviors
- Whether or not binge eating has been a problem
- Problems in the family or other relationships
- Physical and psychological symptoms that occurred before the disorder started
- Physical and psychological symptoms that have occurred since it started
A thorough medical evaluation is also performed in order to assess the physical problems that may have resulted from weight loss, vomiting, and laxative abuse. This involves a complete physical examination and may require blood tests and/or an electrocardiogram.
It is important to rule out other possible physical explanations for the weight loss and become aware of other physical problems that may affect the treatment planning.
