Eating disorders like anorexia nervosa, bulimia nervosa, binge-eating disorder, and other specified feeding or eating disorders (OSFED) can affect people of all ages, genders, and backgrounds. Each of these eating disorders generally has specific symptoms differentiating them from the others, but many of them involve a preoccupation with weight and food, as well as various secretive behaviors. While some online eating disorder quizzes may help you determine whether you or a loved one may be living with disordered eating habits, online quizzes cannot replace the expertise of a licensed medical or mental health professional. If you’d like to ask for help with eating disorder treatments or other mental health challenges, online therapy can be an excellent place to start.

Who do eating disorders impact?

Eating disorders can affect people of all ages, races, genders, and abilities. People may also experience these conditions in all areas of the world. 

What is an eating disorder?

Multiple conditions can be classified under the category of eating disorders. In this section, we’ll discuss some of the most common types of disordered eating. 

Binge eating disorder (BED)

Binge-eating disorder (BED) is a condition in which an individual may eat large amounts of food at one time and may perceive that their behavior is out of control. With this disorder, the person generally does not purge afterward.

This disorder can be far more complex than simply "eating too much" or overeating. A person with BED usually feels ashamed, guilty, or very distressed after a binge. Their binges may be characterized by eating more rapidly than someone ordinarily would, eating large amounts of food when not hungry, and eating alone to avoid others observing their behavior. 

Bulimia nervosa evaluation

Bulimia nervosa is another condition where a person may binge-eat, but unlike those with BED, a person with bulimia normally engages in compensatory behavior following that binge (purging). This usually takes the form of self-induced vomiting. Other possible purging behaviors can include fasting, taking laxatives, or exercising excessively. Much like those with BED, people with bulimia often practice binging and purging behaviors in secret. They may feel ashamed or out of control during these episodes, potentially making it hard to speak out. According to the DSM-5, these episodes must generally occur for three months at least once a week for bulimia to be diagnosed.

Anorexia nervosa assessment

Anorexia nervosa can be a complex condition with a variety of potential contributing factors, but no known single cause. Anorexia is categorized primarily by self-starvation. A person who has anorexia is usually fixated on losing weight or a fear of gaining weight. This fear can be all-consuming and may be paired with body dysmorphia. In addition to self-starvation, people with anorexia may engage in a variety of other behaviors, such as excessive exercise and the use of diuretics.

Other specified feeding or eating disorders (OSFED)

Other Specified Feeding or Eating Disorders, or OSFED, is an umbrella term typically used for feeding or eating disorders that don't necessarily meet the criteria for other diagnoses. OSFED can be extremely harmful and no less severe than other eating disorders. OSFED is sometimes used to describe those with conditions such as atypical anorexia nervosa or purging disorder. This diagnosis may also be given to someone who has experienced the symptoms of BED or bulimia for less than three months.

Warning signs or symptoms of eating disorders

Eating disorders are often extremely serious and can be life-threatening if they are not treated. It can be important to know what to look for if you think that you or someone you know may be living with an eating disorder.

What are some of the warning signs of binge-eating disorder?

If you're not sure about whether you or someone you know has binge-eating disorder, then you might pay attention to some of these warning signs:

  • Extreme concern with body shape and weight

  • Frequent diets and withdrawing from friends or social situations

  • Reluctance to eat in front of other people

  • Stealing or hoarding food in strange places

  • Cutting out entire food groups, like dairy, carbs, or sugars

  • Fluctuations in weight or feelings of low self-esteem 

  • Frequent stomach cramps and other gastrointestinal issues

  • Difficulty concentrating on things that they previously found engaging

What are the signs or symptoms of anorexia nervosa?

When someone has anorexia, their mind may be consumed by their illness. As a result of this, they may isolate themselves socially, act in a way that is "not like themselves," or become highly secretive. That said, many people can be good at hiding their condition and may make excuses to cover up their behavior. You might see significant weight loss, and a person may become noticeably underweight. Some of the other common symptoms of anorexia can be brittle hair and nails, dry skin, complaints of frequent headaches, dizziness or fainting, and abnormal blood work.

What are the signs of bulimia nervosa diagnosis?

Episodes of binging and purging usually categorize bulimia. Typically, someone who experiences bulimia will try to conceal their behavior from those around them and may go to great lengths to do so. After eating a large amount of food, a person with bulimia may vomit afterward, so if someone excuses themselves to use the bathroom after every meal, that could be a potential warning sign. They might also misuse diuretics, laxatives, or exercise to purge. People with bulimia may become depressed or irritable. You might notice broken blood capillaries under their eyes from the force of the vomiting. Other symptoms could include GI issues, secretive behavior, isolation, facial swelling, a sore throat, abnormal blood work, or electrolyte imbalances.

The physical and mental health consequences of eating disorders

Eating disorders can be destructive, painful illnesses to live with. People often feel helpless, but recovery can be possible.

Binge eating disorder

In the case of BED (binge-eating disorder), weight cycling or yo-yo dieting can take place, which may put a strain on your heart. If you do not consume enough calories regularly, it can take a toll on your cardiovascular system because the body may break down its tissues to use as fuel. Your pulse and blood pressure can drop as the heart may have less fuel than it needs to pump blood throughout your body. 

Even though the brain is only about three pounds in weight, it needs approximately one-fifth of the calories that you ingest to function as it should. If you are starving yourself in between binge sessions, the brain may not get the energy that it needs. You may not be able to concentrate, and you may begin to obsess over food out of an instinct for self-preservation.

Your gastrointestinal system can be harmed by BED. This condition can cause blood sugar to fluctuate, which can make you feel faint or pass out. Binge-eating may cause the stomach to rupture in severe cases, which can create a life-threatening emergency.

Bulimia

In the case of bulimia, a person might develop cardiac complications such as an irregular heartbeat. They may also experience heart failure stemming from an electrolyte imbalance, which is why it can be important to seek treatment as soon as you can if you have bulimia. Someone with bulimia may become dangerously dehydrated. They will likely lose sodium, potassium, and chloride from the body, all of which can be essential to basic bodily functions. As with BED, there may be a possibility of stomach rupture in those with bulimia.

Anorexia

Anorexia may also come with a high risk of heart problems and heart failure. An individual's bones may become brittle, and they might develop osteoporosis or osteopenia. Moreover, they may experience fainting from low blood sugar or other complications. They might have muscle weakness or muscle loss, and their kidneys can fail because of dehydration. Those who have periods may experience loss of their menstrual cycle or abnormalities in their menstrual cycle.

Eating disorder evaluation tests or online quiz

If you search the internet, you may find tests that claim to be able to help you determine if you might have the symptoms of an eating disorder. When you take an eating disorder test, you may answer each question on a scale from "Not at All" to "All the Time." The queries may be things like, "Have you had the desire for a flat stomach?" and, "Have you felt fat?" At the end of the quiz, they'll generally give you their opinion on whether there's a possibility that you have an eating disorder. One of the most reputable online quizzes for eating disorders can be found on the National Eating Disorder Association website.

How effective are online eating disorder assessment tests?

The effectiveness of online eating disorder quizzes can be hard to gauge. After all, no online test may be a valid substitute for seeing a licensed mental health professional. Some of the questions can be vague, and since no two people with an eating disorder may be alike, nor must you experience every symptom to receive an eating disorder diagnosis, an online test can't usually tell you with certainty if you have an eating disorder. If you believe you may have an eating disorder, please reach out for professional help and avoid self-diagnosis.

If you're searching for an eating disorder test online, it likely means you're wondering whether you could have an eating disorder. Considering the many health risks that can be associated with eating disorders, it may be imperative that you seek help. Early detection can help you avoid some of the long-term effects of eating disorders, but it may never be too late to get help and start recovery. 

Seek out a therapist specializing in different eating disorders

If you're experiencing symptoms of an eating disorder, it can be crucial to talk to your doctor. You might ask if they have a recommendation for a therapist who specializes in the treatment of eating disorders. It can be best to make a preliminary appointment with that provider, as they will likely be able to give you a more accurate diagnosis than any online quiz.

For immediate assistance, you can call the National Eating Disorder Association Helpline at 1-800-931-2237 (M-Th: 9 AM-9 PM EST, Fri 9 AM - 5 PM EST). 

Tell loved ones about the situation

You might have the urge to hide what is happening from your family or loved ones. It can be common to have intense feelings of shame or guilt about living with an eating disorder. However, research indicates that when families are involved in the eating disorder recovery process, there is often a higher level of success. Your family can be part of the support network you deserve so that you can get well and develop a healthier relationship with food.

Online therapy can be an option

Reaching out for help with an eating disorder can be challenging. Some individuals experiencing disordered eating may have an especially hard time talking about their problems in person. This could be due to shame around the disorder or difficulty going out in public for fear of judgment. Whatever the case, online therapy for eating disorders can offer an alternative. In this setting, you may feel more comfortable opening up about your feelings and challenges. 

Effectiveness of online therapy for mental health

A recent study found evidence that certain types of online therapy for eating disorders, such as imaginal exposure therapy, were typically associated with positive outcomes. These included fewer symptoms of disordered eating as well as a decrease in fear of food and weight gain. 

Takeaway

Common eating disorders can include binge-eating disorder, bulimia nervosa, anorexia nervosa, and OSFED, or other specified feeding or eating disorders. These disorders can affect all types of people, regardless of gender, background, or age. Although you may come across many online eating disorder quizzes that may claim to be able to determine whether you have an eating disorder, it can be crucial to get a licensed medical or mental health professional’s opinion. Online quizzes may not be accurate and cannot replace the expertise of a professional. If you or a loved one needs help with eating-related issues, online therapy can be an effective tool to help you connect with a therapist.
