- Eating Disorders -

There is a commonly held misconception that eating disorders are a lifestyle choice. Eating disorders are actually serious and often fatal illnesses that are associated with severe disturbances in people’s eating behaviors and related thoughts and emotions. Preoccupation with food, body weight, and shape may also signal an eating disorder. Common eating disorders include anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Signs and Symptoms of Eating Disorders

Anorexia nervosa

Anorexia nervosa is a condition where people avoid food, severely restrict food, or eat very small quantities of only certain foods. They also may weigh themselves repeatedly. Even when dangerously underweight, they may see themselves as overweight.

There are two subtypes of anorexia nervosa: a "restrictive" subtype and a "binge-purge" subtype.

In the restrictive subtype of anorexia nervosa, people severely limit the amount and type of food they consume.
In the binge-purge subtype of anorexia nervosa, people also greatly restrict the amount and type of food they consume. In addition, they may have binge-eating and purging episodes—eating large amounts of food in a short time followed by vomiting or using laxatives or diuretics to get rid of what was consumed.

Anorexia nervosa can be fatal. It has an extremely high death (mortality) rate compared with other mental disorders. People with anorexia are at risk of dying from medical complications associated with starvation. Suicide is the second leading cause of death for people diagnosed with anorexia nervosa.

If you or someone you know is struggling or having thoughts of suicide, call or text the 988 Suicide & Crisis Lifeline at 988 or chat at 988lifeline.org . In life-threatening situations, call 911.

Symptoms include:

Extremely restricted eating
Extreme thinness (emaciation)
A relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight
Intense fear of gaining weight
Distorted body image, a self-esteem that is heavily influenced by perceptions of body weight and shape, or a denial of the seriousness of low body weight

Other symptoms may develop over time, including:

Thinning of the bones (osteopenia or osteoporosis)
Mild anemia and muscle wasting and weakness
Brittle hair and nails
Dry and yellowish skin
Growth of fine hair all over the body (lanugo)
Severe constipation
Low blood pressure
Slowed breathing and pulse
Damage to the structure and function of the heart
Brain damage
Multiorgan failure
Drop in internal body temperature, causing a person to feel cold all the time
Lethargy, sluggishness, or feeling tired all the time
Infertility

Bulimia nervosa

Bulimia nervosa is a condition where people have recurrent and frequent episodes of eating unusually large amounts of food and feeling a lack of control over these episodes. This binge-eating is followed by behavior that compensates for the overeating such as forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. People with bulimia nervosa may be slightly underweight, normal weight, or over overweight.

Symptoms include:

Chronically inflamed and sore throat
Swollen salivary glands in the neck and jaw area
Worn tooth enamel and increasingly sensitive and decaying teeth as a result of exposure to stomach acid
Acid reflux disorder and other gastrointestinal problems
Intestinal distress and irritation from laxative abuse
Severe dehydration from purging of fluids
Electrolyte imbalance (too low or too high levels of sodium, calcium, potassium, and other minerals) which can lead to stroke or heart attack

Binge-eating disorder

Binge-eating disorder is a condition where people lose control over their eating and have reoccurring episodes of eating unusually large amounts of food. Unlike bulimia nervosa, periods of binge-eating are not followed by purging, excessive exercise, or fasting. As a result, people with binge-eating disorder often are overweight or obese. Binge-eating disorder is the most common eating disorder in the U.S.

Symptoms include:

Eating unusually large amounts of food in a specific amount of time, such as a 2-hour period
Eating even when you're full or not hungry
Eating fast during binge episodes
Eating until you're uncomfortably full
Eating alone or in secret to avoid embarrassment
Feeling distressed, ashamed, or guilty about your eating
Frequently dieting, possibly without weight loss

Avoidant restrictive food intake disorder

Avoidant restrictive food intake disorder (ARFID), previously known as selective eating disorder, is a condition where people limit the amount or type of food eaten. Unlike anorexia nervosa, people with ARFID do not have a distorted body image or extreme fear of gaining weight. ARFID is most common in middle childhood and usually has an earlier onset than other eating disorders. Many children go through phases of picky eating, but a child with ARFID does not eat enough calories to grow and develop properly, and an adult with ARFID does not eat enough calories to maintain basic body function.

Symptoms include:

Dramatic restriction of types or amount of food eaten
Lack of appetite or interest in food
Dramatic weight loss
Upset stomach, abdominal pain, or other gastrointestinal issues with no other known cause
Limited range of preferred foods that becomes even more limited (“picky eating” that gets progressively worse)

Risk Factors

Eating disorders can affect people of all ages, racial/ethnic backgrounds, body weights, and genders. Eating disorders frequently appear during the teen years or young adulthood but may also develop during childhood or later in life.

Researchers are finding that eating disorders are caused by a complex interaction of genetic, biological, behavioral, psychological, and social factors. Researchers are using the latest technology and science to better understand eating disorders.

One approach involves the study of human genes. Eating disorders run in families. Researchers are working to identify DNA variations that are linked to the increased risk of developing eating disorders.

Brain imaging studies are also providing a better understanding of eating disorders. For example, researchers have found differences in patterns of brain activity in women with eating disorders in comparison with healthy women. This kind of research can help guide the development of new means of diagnosis and treatment of eating disorders.

Treatments and Therapies

It is important to seek treatment early for eating disorders. People with eating disorders are at higher risk for suicide and medical complications. People with eating disorders can often have other mental disorders (such as depression or anxiety) or problems with substance use. Complete recovery is possible.

Treatment plans are tailored to individual needs and may include one or more of the following:

Individual, group, and/or family psychotherapy
Medical care and monitoring
Nutritional counseling
Medications

Psychotherapies

Family-based therapy, a type of psychotherapy where parents of adolescents with anorexia nervosa assume responsibility for feeding their child, appears to be very effective in helping people gain weight and improve eating habits and moods.

To reduce or eliminate binge-eating and purging behaviors, people may undergo cognitive behavioral therapy (CBT), which is another type of psychotherapy that helps a person learn how to identify distorted or unhelpful thinking patterns and recognize and change inaccurate beliefs.

Medication

Evidence also suggests that medications such as antidepressants, antipsychotics, or mood stabilizers may also be helpful for treating eating disorders and other co-occurring illnesses such as anxiety or depression. The Food and Drug Administration’s (FDA) website has the latest information on medication approvals, warnings, and patient information guides.
