Anorexia Nervosa: Diagnosis, Treatment, and Resources
Anorexia nervosa is marked by self starvation with food refusal, food rules, rigid eating behaviors, and a persistent irrational fear of gaining weight that does not resolve with continued weight loss. It lies on the restrictive end of the eating disordered spectrum and many times people who suffer with this disorder are not able see or experience how much weight they are losing. Often it can feel like the eating disorder and your brain are congratulating you for ignoring your body’ signals to feed yourself; society reinforces this with compliments at lower weight. However, anorexia and other eating disorders are the most fatal mental illness, and it is important to seek treatment from a health professional. Learn about anorexia nervosa diagnosis and treatment below.
Definition, Symptoms, and Diagnosis
What is anorexia nervosa? Anorexia nervosa (AN) is the restriction of food intake leading to reduction of body weight to below what is deemed acceptable and normal for the individual’s age and height. Additionally, this is accompanied by a fear of gaining weight or becoming overweight, despite the person being significantly under a healthy weight. Individuals with anorexia nervosa typically do not realize and have difficulty acknowledging that they are seriously and dangerously underweight.
Anorexia has the highest mortality rate of all psychiatric illnesses due to starvation and malnutrition; however, full recovery is possible and early treatment is the best step.
How common is anorexia nervosa?
Anorexia nervoa affects 0.9% of American women at some point in their lives. 50-80% of the risk for anorexiais genetic, and nearly half of anorexia patients have a co-occuring mood disorder such as depression.
What are the signs and symptoms of anorexia nervosa?
- Avoiding or skipping meals
- Pushing food around on a plate or hiding it under a plate or napkin
- Adopting a restrictive or extreme diet and sometimes under the guise of trying to be healthy. For example, become a vegetarian and using this as the reason why they aren’t eating certain things.
- Worry and shame about eating and getting fat
- Eating meals alone and refusing to eat in front of others
- Significant and sudden weight loss disguised by wearing baggy clothes to hide these changes
- Defensiveness about any comments that indicate noticing these behaviors
How do you diagnose anorexia nervosa?
The best way to assess whether you or your loved one is suffering from anorexia nervosa is to meet with an eating disorder specialist and get a full psychological and physical exam. Your therapist or psychiatrist will use the DSM-V (Diagnostics and Statistics Manual), a manual to diagnose mental health conditions. According to the DSM-V, the criteria for diagnosing anorexia nervosa includes:
- Restriction of food relative to the individual’s height, weight, age, gender, physical health, and development that leads to significantly low body weight.
- Intense fear of gaining weight and persistent behavior that prevents weight gain, despite being underweight.
- Distortion of one’s body weight or shape, or a lack of insight into the seriousness of how low the person’s weight is.
- Restriction of food intake without the use of any means of eliminating the food (vomiting or using laxatives, diuretics, or enemas) or without any episodes of binge eating. The weight loss is due primarily to severe dieting, fasting, and/or excessive exercising.
Additionally, there are specifications about the severity of the condition, determined by the individual’s Body Mass Index (BMI).
What is atypical anorexia nervosa?
Atypical anorexia is defined by the DSM-V as having met all criteria for anorexia except for meeting a normal or above normal weight, which makes this difficult to diagnose. Individuals with this condition often go without treatment or are even turned away from doctors because they don’t “look sick”.
What are medical complications of anorexia nervosa?

- Bradycardia- heart rate dropping to a dangerously low rate of under 60 beats per minute

Cognitive behavioral therapy (CBT) has been proven through decades of research to be one of the most effective treatments for anorexia nervosa.

Residential treatment centers as well as hospitalization may also be necessary depending on the severity of the condition. Self-help and support groups are also helpful with recovery.
How can you help someone with anorexia nervosa?
The most important way to help a friend or loved one with anorexia is to be compassionate and understanding, even if you may not be able to fully understand what the individual may be experiencing. Let the person know that you are there to listen and that you won’t judge them. Avoid advising; rather, think more about listening and validating feelings. Researching the disorder to understand it better can be helpful, too. Ask if they are in treatment and what you can do as their friend or loved one to help support their treatment.
