Eating disorders are conditions where people either restrict or cannot control their food intake. They are serious conditions that lead to very severe and serious medical problems. They develop most frequently during adolescence and early adulthood, and affect women more than men. They are about eating and food, but eating disorders are also more than that. For many people eating disorders are about control, and easing feelings of stress and anxiety.
Eating disorders are often overcome through treatment, while in some cases people relapse and in other cases it can be very hard for a person to overcome their eating disorder for any period of time.
Types of Eating Disorders
The three most common types of eating disorders are anorexia nervosa, bulimia nervosa, and binge-eating disorder. They share some common features, but each of these disorders is unique and a condition in its own right.
Individuals with anorexia nervosa, also referred to just as anorexia, have intense fears of gaining weight and take actions to prevent it. They will think about food and eating very often and will take serious measures to limit the amount of food they eat. According to the US Office on Women’s Health, anorexia is also about more than just food; it’s about control. By strictly controlling their food intake, people with anorexia may feel more in control of life and ease tensions and anxieties they normally experience.
Symptoms of anorexia include:
- Having a low BMI, or low body weight for height
- Resisting maintaining a normal weight, or denying the fact that they are underweight
- Intensely fearing gaining weight
- Holding the belief that they are fat although they are very thin, or have an otherwise distorted body image
- Missing 3 menstrual periods in a row
There are other behaviors that can help a person identify anorexia, according to the National Institute on Mental Health. Someone with anorexia may portion their food carefully and move food around on their plates to make it seem like they ate more than they did. Another sign of anorexia is frequent weighing, where someone will step on the scale very often. Others may exercise excessively, misuse laxatives, or self-induce vomiting. In addition, someone with anorexia may be cold often, and will wear several layers of clothing because of this, and because of the desire to cover up their body.
Potential consequences of anorexia include:
- Thinning of the bones
- Brittle hair and nails
- Dry, yellowish skin
- Growth of fine hair all over the body
- Mild anemia, muscle wasting and weakness
- Severe constipation
- Low blood pressure
- Damage to the heart
- Lethargy, feeling tired all of the time
Bulimia nervosa is another type of eating disorder. This is characterized by having recurrent and frequent episodes of eating large amounts of food and feeling a lack of control over it. Binge-eating in cases of bulimia is followed by behavior that compensates for this kind of eating, such as forced vomiting, excessive and deliberate use of laxatives, fasting, excessive exercise, or a combination of these things.
People with bulimia tend to maintain a healthy weight, unlike people with anorexia, and some people are slightly overweight. Individuals with bulimia normally desire to lose weight and express unhappiness with their weight, shape, and size. According to the National Institute of Mental Health, binge and purge cycles take place anywhere from several times a week to many times a day.
Signs of bulimia nervosa include:
- Using diet pills, laxatives, or pills that encourage urination often
- Going to the bathroom frequently after eating
- Exercising excessively, even if hurt or tired or in bad weather
- Signs of throwing up, especially after eating, such as having a swollen jaw or cheeks, calluses/scrapes on the knuckles, teeth that look clear, broken blood vessels in the eyes
- Acid reflux disorder and other gastrointestinal problems
- Severe dehydration
- Electrolyte imbalance
According to the US Office of Women’s Health, people with bulimia often have other mental health conditions including depression, anxiety, and substance abuse problems.
Binge-eating disorder is an eating disorder in which people entirely lose control over what they are eating. It is different from bulimia, however, and periods of binge-eating are not followed by weight loss efforts such as purging, excessive exercise, or fasting. As a result of their behavior, binge-eaters are often overweight or obese.
Binge-eaters may also:
- Eat more quickly than usual when in a binge episode
- Eat to the point of uncomfortable fullness
- Eat even though they are not hungry
- Eat alone because of embarrassment
- Feel disgusted, depressed, or guilty after overeating
Potential Consequences of Binge Eating Disorder
Given the fact that binge-eating disorder often leads to weight gain and obesity, it can also cause related issues. Obesity raises the risk for type 2 diabetes, high blood pressure, high cholesterol, gallbladder disease, heart disease and certain types of cancer. According to the Office on Women’s Health, binge eaters also often are affected by anxiety, depression and/or personality disorders.
Types of Eating Disorder Treatment
The foundations of all eating disorder treatment are teaching and encouraging adequate nutrition, stopping purging behaviors, and reducing excessive exercise. Psychotherapy (talk therapy) and medications are effective across many different cases of eating disorders.
According to the National Institute on Mental Health, all treatment plans for eating disorders should include:
- Individual, group and/or family psychotherapy
- Medical care and monitoring
- Nutritional Counseling
Problems caused by malnutrition, obesity, and purging would need to be addressed on an as-needed basis. For example, if someone with binge-eating disorder developed diabetes they would require treatment for that condition, as would a person with anorexia who developed osteoporosis.
The different types of eating disorders do require somewhat of different types of treatment. They are described below.
Anorexia Nervosa Treatment
Treatment for anorexia nervosa involves three main components:
- Restoring the individual to a healthy body weight
- Treating the psychological issues related to the eating disorder
- Reducing or eliminating behaviors or thoughts that lead to insufficient eating and preventing relapse
This is most often done through family, group, and individual psychotherapy along with medical monitoring and nutritional counseling. In some cases, medications may be prescribed as well. Antidepressants, antipsychotics, or mood stabilizers have shown to help resolve the mood and anxiety aspects of eating disorders for some people.
According to the American Psychological Association, a special family therapy approach called the Maudsley approach is regarded as effective as well, especially in adolescents. In this approach, counselors work with patients and their parents, and enlist their parents to encourage healthy eating and to take responsibility for their child’s eating.
Bulimia Nervosa Treatment
Treatment for bulimia nervosa is similar to that for anorexia. It often involves a combination of psychotherapy, nutritional counseling, and may involve medications. Bulimia treatment, however, sometimes involves cognitive-behavioral therapy (CBT). CBT is used to help individuals identify patterns of thought, behavior, and belief that lead them to binge and purge. When identified, counselors work with patients in helping them change these patterns and to avoid their dangerous behaviors of binge eating and subsequently purging.
In addition, treatment should identify any residual effects of bulimia and help the patient to remedy these effects.
Treatment for Binge-Eating Disorder
Binge-eating disorder treatment is very similar to bulimia nervosa treatment. CBT that is tailored to the individual, whether given in individual or group environments, has been shown to be effective in helping people control their binge eating. Medications, especially antidepressants, may be helpful as well.
As with the other eating disorders, treatment for binge-eating disorder must address any potential side effects or consequences of the disorder, such as diabetes.
Causes of Eating Disorders
There is no one exact cause of eating disorders, though there are many potential contributing factors. These illnesses are serious medical conditions that manifest in both mind and body. Some factors that contribute to the development of eating disorders are:
- Genetic factors. People with families members who have eating disorders are more likely to develop one themselves. Further study needs to be done to determine if this has a biological basis or is due to more nurture-related causes.
- Culture. A certain ideal of beauty tends to be portrayed in popular media, and it can be difficult for people to to deal with the pressure of fitting into that ideal. With images of the ‘perfect body’ and how they should look pervading their lives, it is tough not to compare yourself and put those standards on yourself.
- Life changes or stressful events. Big changes in life such as a bad break up, a parent’s divorce or death, and traumatic events like rape can set off eating disorders, especially anorexia.
- Personality traits. Some people with eating disorders may generally feel hopeless or unhappy with themselves. They may be a perfectionist and set hard to reach goals for themself – including for their appearance.
- Other emotional disorders. Depression and anxiety often co-occur with eating disorders. Whether they are a cause or a symptom is unclear, and may vary depending on the person.
- Families and social pressures. The way parents think about and talk about their kids’ appearance and diet may affect how they feel about it, and can lead to an eating disorder.
Prevalence of Eating Disorders
The prevalence of eating disorders in America is fairly well documented, as are statistics concerning the age, race, and gender of people with the disorder. It seems that eating disorders affect women much more than men, and typically have their onset in adolescence or young adulthood.
Here are some eating disorder statistics that explain their prevalence:
- In 13-18 year olds 2.7% have some form of an eating disorder. (National Institute of Mental Health)
- 3.8% of American females are affected by an eating disorder, while 1.5% of males are affected.(National Institute of Mental Health)
- 0.1% of children aged 8 to 11 have an eating disorder, while 0.2% of children 12 to 15 years old have an eating disorder. (National Institute of Mental Health)
- Only 1 in 10 men and women with eating disorders receives treatment. (National Association of Anorexia Nervosa and Related Disorders)
- Eating disorders have one of the highest mortality rates of any mental health condition. (National Association of Anorexia Nervosa and Related Disorders)
- 10 to 15% of people with anorexia or bulimia are male. (National Association of Anorexia Nervosa and Related Disorders)
