Anorexia
Anorexia nervosa (commonly referred to as anorexia) is a serious mental health condition that can drastically impair a person’s physical health. When a person severely restricts food intake and limits or eliminates vital nutrients, their body’s systems can begin to slow down, leading to several potential short- and long-term effects – many of which can be fatal.
Anorexia has one of the highest death rates of any mental illness, claiming the lives of between 5-20% of the people who suffer from it.1 Recognizing the signs and symptoms of anorexia can help a person get treatment early, which increases the chance of recovery.

What Is Anorexia?
Anorexia nervosa is an eating disorder that causes people to lose an unhealthy amount of weight. It is characterized by a fear of gaining weight even in those who are already underweight or may be dieting and exercising to lose weight.
Anorexia is far more common in females. But it can occur in males as well. It is a severe illness that can be life-threatening if not treated.1,2
Many celebrities have battled anorexia. Read about a few of them below.

Signs and Symptoms
A person must meet certain criteria to be officially diagnosed with anorexia. The Diagnostic and Statistical Manual of Mental Disorders, 5th Ed. (DSM-V) outlines the following 3 criteria:3
- Severe fear of becoming fat or gaining weight, even though the person is medically underweight based on body mass index (BMI).
- Distorted perception of one’s body weight and shape, denial of the seriousness of being underweight, or over-influence of body shape or weight on one’s evaluation of self.
- Restricting caloric intake, which leads to lower energy levels and significantly low body weight for one’s age, height, physical health, and development.

What Causes Anorexia?
The exact causes of anorexia aren’t fully understood. It is complex illness that may have many contributing factors.
- It can begin after a stressful life event, such as leaving home for college, moving to a new place, or breaking up with a significant other.
- It may also be caused by inherited biological and personality traits. For example, some people may have a genetic predisposition to traits such as perfectionism and sensitivity, which are both associated with anorexia.5,6
- People who are goal-oriented and high achievers are also more susceptible to the condition.2
Risk Factors
Certain risk factors can predispose a person to developing anorexia. These include:1, 2, 5, 6, 7
- Genetics: Research studies on twins suggest that between 30-75% of cases of anorexia occur because of heritability.7
- Culture: Modern Western culture places a strong emphasis on being thin, especially for women. Many people equate their self-worth and feelings of success with their body weight and size, which can lead them to take drastic measures to achieve such ideals. 5,6
- Peer pressure: Those who feel a significant amount of peer pressure to stay thin may also be more likely to develop anorexia. Peer pressure is especially common in teenagers, who are heavily influenced by their peers’ opinions.5
- Age: People of all ages can develop anorexia. But it is most common in young people and rarely occurs in people over the age of 40. Teenagers are the most susceptible. According to research, 3 out of every 100 teens develops anorexia.6
- Gender: As many as 90-95% of people who suffer from anorexia are girls or women.1
- Family history of an eating disorder: Having a first-degree relative (parent, child, or sibling) who has had anorexia greatly increases a person’s risk. 5,6
- Certain occupations: Models, athletes, and performers (dancers, actors, etc.) are at a higher risk for developing anorexia because they often face significantly more pressure to look a certain way. 5,6
- Life transitions: Any major life transition such as changing schools or jobs, breaking up with a partner, losing a loved one, or moving to a new home can increase a person’s risk for anorexia and similar eating disorders. 5,6
- Psychological difficulties: Negative self-image, coping with painful or overwhelming emotions, or recovering from trauma can all increase a person’s susceptibility to anorexia. 2,6
Short-Term Effects
Anorexia causes many physical complications and health problems. Many anorexia effects can be severe and even life-threatening.
Some of the short-term effects of anorexia include:1,4,5
- Weight loss.
- Dehydration.
- Dry skin and hair.
- Nausea.
- Constipation.
- Fatigue.
- Dizziness.
- Fainting.
- Insomnia.
If you or someone you love is experiencing any of the above anorexia effects, seek help as soon as possible. Your insurance may cover anorexia treatment. According to experts, seeking treatment early on greatly increase a person’s chance of recovery and can significantly reduce the risk of more serious complications.1
Long-Term Effects
If left untreated, a person with anorexia can suffer many long-term health effects, such as:1,4,5
- Bone weakening (osteoporosis).
- Anemia.
- Seizures.
- Thyroid problems.
- Lack of vitamins and minerals.
- Low potassium levels in the blood.
- Decrease in white blood cells.

Side Effects
In addition to the physical health problems that anorexia causes, a person may have other anorexia side effects, such as:
- Mood swings.
- Lowered self-esteem and self-worth.
- Strained personal relationships.
- Poor school and work performance.
- Missing out on important activities.
- Lying to others.
- Avoiding social situations where food is present.
Though perhaps not as dire as anorexia’s health complications, these social, emotional, and behavioral changes can have significant negative impacts on a person’s life.
Depression and Anorexia
Many people with anorexia suffer from depression and may exhibit symptoms such as:
- Depressed mood.
- Irritability.
- Insomnia.
- Social withdrawal.
- Reduced interest in sex.
Many of these symptoms may be related to semi-starvation or from being heavily focused on eating and weight.
Depression and anorexia can influence each other. A person may have depression, which leads to anorexia. Alternatively, a person suffering from anorexia may develop depression because of their illness.
