Anorexia, formally known as anorexia nervosa, is an eating disorder. People with anorexia limit the number of calories and the types of food they eat. Eventually, they lose weight or cannot maintain an appropriate body weight based on their height, age, stature and physical health. They may exercise compulsively and/or purge the food they eat through intentional vomiting and/or misuse of laxatives.
Individuals with anorexia also have a distorted self-image of their body and have an intense fear of gaining weight.
Anorexia is a serious condition that requires treatment. Extreme weight loss in people with anorexia can lead to malnutrition, dangerous health problems and even death.
What are the signs and symptoms of anorexia?
You cannot tell if a person has anorexia just by their appearance because anorexia also involves mental and behavioral components — not just physical. A person does not need to be underweight to have anorexia. Larger-bodied individuals can also have anorexia. However, they may be less likely to be diagnosed due to cultural stigma against fat and obesity. In addition, someone can be underweight without having anorexia. Remember, anorexia also includes psychological and behavioral components as well as physical.
There are several emotional, behavioral and physical signs and symptoms of anorexia. If you or someone you know experiences the signs and symptoms of anorexia below, it’s important to seek help.
The biggest challenge in treating anorexia is helping the person recognize and accept that they have an illness. Many people with anorexia deny that they have an eating disorder. They often seek medical treatment only when their condition is serious or life-threatening. This is why it’s important to diagnose and treat anorexia in its beginning stages.
The goals of treatment for anorexia include:
Stabilizing weight loss.
Beginning nutrition rehabilitation to restore weight.
Eliminating binge eating and/or purging behaviors and other problematic eating patterns.
Treating psychological issues such as low self-esteem and distorted thinking patterns.
Developing long-term behavioral changes.
People with eating disorders, including anorexia, often have additional mental health conditions, including:
These conditions can further complicate anorexia, so if an individual has one or more of these conditions, their healthcare team will likely recommend treatment for the condition(s) as well.
Treatment options will vary depending on the individual’s needs. A person may receive treatment through residential care (outpatient care) or hospitalization depending on their current medical and mental health state. Treatment for anorexia most often involves a combination of the following strategies:
Psychotherapy.
Medication.
Nutrition counseling.
Group and/or family therapy.
Hospitalization.
Psychotherapy
Psychotherapy is a type of individual counseling that focuses on changing the thinking (cognitive therapy) and behavior (behavioral therapy) of a person with an eating disorder. Treatment includes practical techniques for developing healthy attitudes toward food and weight, as well as approaches for changing the way the person responds to difficult situations. There are several types of psychotherapy, including:
Acceptance and commitment therapy: This therapy’s goal is to develop motivation to change actions rather than your thoughts and feelings.
Cognitive behavioral therapy (CBT): This therapy’s goal is to address distorted views and attitudes about weight, shape and appearance and to practice behavioral modification (if “X” happens, I can do “Y” instead of “Z”).
Cognitive remediation therapy: This therapy uses reflection and guided supervision to develop the capability of focusing on more than one thing at a time.
Dialectical behavior therapy (DBT): This therapy helps you not just develop new skills to handle negative triggers but also helps you develop insight to recognize triggers or situations where a non-useful behavior might occur. Specific skills include building mindfulness, improving relationships through interpersonal effectiveness, managing emotions and tolerating stress.
Family-based therapy (also called the Maudsley Method): This therapy involves family-based refeeding, which means putting the parents and family in charge of getting the appropriate nutritional intake consumed by the person with anorexia. It’s the most evidence-based method to physiologically restore health to an individual with anorexia who is under 18 years of age.
Interpersonal psychotherapy: This therapy is aimed at resolving an interpersonal problem area. Improving relationships and communications and resolving identified problems may reduce eating disorder symptoms.
Psychodynamic psychotherapy: This therapy involves looking at the root causes of anorexia as the key to recovery.
A healthcare provider can diagnose a person with anorexia based on the criteria for anorexia nervosa listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published by the American Psychiatric Association. The three criteria for anorexia nervosa under the DSM-5 include:
Restriction of calorie consumption leading to weight loss or a failure to gain weight resulting in a significantly low body weight based on that person’s age, sex, height and stage of growth.
Intense fear of gaining weight or becoming “fat.”
Having a distorted view of themselves and their condition. In other words, the individual is unable to realistically assess their body weight and shape believes their appearance has a strong influence on their self-worth and denies the medical seriousness of their current low body weight and/or food restriction.
Even if all of the DSM-5 criteria for anorexia aren’t met, a person can still have a serious eating disorder. DSM-5 criteria classifies the severity of anorexia according to body mass index (BMI). Individuals who meet the criteria for anorexia but who aren’t underweight despite significant weight loss have what’s known as atypical anorexia.
Diagnostic guidelines in the DSM-5 also allow healthcare providers to determine if a person is in partial remission (recovery) or full remission as well as to specify the current severity of the condition based on body mass index (BMI).
If signs and symptoms of anorexia are present, a healthcare provider will begin an evaluation by performing a complete medical history and physical examination. The provider or a mental health professional will likely ask questions about the following topics:
Dietary history (attitudes about food, dietary restriction).
Exercise history.
Psychological history.
Body image (this includes behaviors such as how often you weigh yourself).
Bingeing and purging frequency and elimination habits (use of diet pills, laxatives and supplements).
Family history of eating disorders.
Menstrual status (if your periods are regular or irregular).
Medication history.
Prior treatment.
It’s important to remember that a person with anorexia or any eating disorder will have the best recovery outcome if they receive an early diagnosis. If you or someone you know is experiencing signs and symptoms of anorexia, be sure to talk to a healthcare provider as soon as possible.
What tests are used to diagnose or assess anorexia?
Although there are no laboratory tests to specifically diagnose anorexia, a healthcare provider may use various diagnostic tests, such as blood tests, to rule out any medical conditions that could cause weight loss and to evaluate the physical damage weight loss and starvation may have caused.
Tests to rule out weight-loss causing illness or to assess anorexia side effects may include:
A pregnancy test in people assigned female at birth who are of childbearing age.
Hormone tests if evidence of menstrual problems in people assigned female at birth (to rule out other causes) and measuring testosterone in people assigned male at birth.
