Raising awareness and spreading eating disorders education can be important because early identification may help a person with an eating disorder recover. Parents, teachers, doctors, friends, and family members alike may become attuned to the signs and symptoms of eating disorders, helping those who have them receive early diagnoses. When a person is diagnosed with an eating disorder, they can begin treatment that fosters healing.

Organizations like the government-funded National Center of Excellence for Eating Disorders (NCEED) and the nonprofit organization National Eating Disorders Awareness (NEDA) primarily work to educate and raise awareness related to eating disorders. Both organizations provide facts and statistics related to how eating disorders can impact physical and mental health. They also discuss how others can identify eating disorder signs and symptoms and support people living with these conditions. In this article, we describe the importance of eating disorders education, signs and symptoms of common eating disorders, and potential treatment options, including therapy.

Early eating disorders detection

Experts stress the benefits of detecting eating disorders early, reporting that the early detection of eating disorders can improve outcomes, decrease mortality, and prevent physical and psychiatric complications. 

In peer-reviewed articles, experts have suggested that early eating disorder detection could be promoted by educating teachers, school personnel, coaches, doctors, and parents on eating disorders. This education could make people more likely to notice when an eating disorder is present and be more confident to speak up about it and take action. 

Since eating disorders often first appear in adolescence, educating those who care for, teach, or otherwise regularly interact with adolescents can be one strategy for increasing the early detection of eating disorders.  

Signs of eating disorders

Early detection of eating disorders usually begins with a person recognizing certain signs. Different eating disorders have different diagnostic criteria, which we will discuss below. However, there are some general signs for which to look, according to the National Eating Disorders Association

Here are some of the potential signs of eating disorders:

  • A preoccupation with weight loss, dieting, calories, or food in general
  • A preoccupation with body size, body shape, or one's appearance
  • A refusal to eat certain foods or whole food groups
  • Excuses to avoid meals 
  • Noticeable weight changes
  • Menstrual cycle irregularities
  • Physical symptoms, like digestive complaints, frequently feeling cold, muscle weakness, dry skin and hair, sleep problems, dental problems, nutrient deficiencies, or dizziness
  • Excessively exercising
  • Eating in secret or hiding food

Types of eating disorders

Eating disorders are defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V). Currently, there are five main categories of eating disorders.

Anorexia nervosa

Anorexia nervosa generally involves restricted eating fueled by a negative body image, in which a person believes they are overweight even when they are of a normal weight or even underweight. 

Undereating often causes a person with anorexia nervosa to lose a significant amount of weight as they pursue thinness. In addition to restricting eating, one form of anorexia nervosa also involves binge eating followed by purging (forced vomiting to remove the food that was just eaten and avoid gaining weight). Anorexia nervosa usually comes with an increased risk of many physical health problems, including nutrient deficiencies and severe dehydration.
Bulimia nervosa

Like anorexia nervosa, bulimia nervosa usually involves a preoccupation with weight loss and attaining a low body weight. Instead of restriction, bulimia nervosa is typically characterized by binge eating large quantities of food, often quickly. Binges are usually followed by what is called “compensatory behavior,” or actions intended to compensate for the binge. 

Compensatory behaviors may include vomiting, taking laxatives or diuretics, fasting, or engaging in excessive exercise. While people with anorexia nervosa are often underweight, those with bulimia nervosa may have a fluctuating weight and at times may have a normal weight or be overweight.

Binge eating disorder

In binge eating disorder, a person normally has recurring binge eating episodes. During these moments, they usually sense they are out of control and believe they are unable to stop themselves from eating. 

People with binge eating disorder often feel great shame and distress over their eating. For this reason, they may hide food or eat in secret. People with binge eating disorder often, but not always, are overweight or obese. Binge eating can differ from bulimia nervosa in that people do not usually engage in compensatory behaviors after binge eating.

Avoidant/restrictive food intake disorder (ARFID)

People who have avoidant/restrictive food intake disorder (ARFID) often undereat and may avoid entire categories of food. ARFID usually begins in childhood. To many, ARFID may look like "picky eating," but it can come with serious consequences, like nutritional deficiencies and developmental delays. 

Unlike people with other eating disorders, those with ARFID don't usually fear gaining weight. Instead, they often avoid foods out of fear of vomiting or choking, disgust, or other negative feelings related to the food's taste or texture. People with ARFID are generally not preoccupied with weight, size, or body image.

Other specified feeding or eating disorder (OSFED)

Some eating patterns that involve disordered eating but do not fit clearly in one of the already mentioned categories are categorized as other specified feeding or eating disorders (OSFEDs).

Depending on the type of OSFED a person has, they may restrict their food or engage in binge eating and purging. Although OSFED is sometimes discussed as if it's a less serious eating disorder, NEDA emphasizes that OSFED is actually the most common eating disorder, and it is just as serious as anorexia nervosa, bulimia nervosa, and binge eating disorder.

Disordered eating habits research

Although updated evidence may be needed, research suggests that many people engage in disordered eating habits, even those who do not meet the criteria for an eating disorder.  Disordered eating can negatively impact a person's health and nutrition. As with eating disorders, identifying disordered eating habits early may prevent negative outcomes and complications.

In general, disordered eating involves many of the same symptoms seen in eating disorders. Often, these symptoms occur on their own or do not occur frequently or severely enough to be considered an eating disorder. Indicators of disordered eating may include skipping meals, using food substitutes, eating very little, taking diet pills, vomiting, taking laxatives or diuretics, and binge eating.

Healthy eating habits

Healthy eating habits generally refer to those that provide adequate nutrition, which can protect against deficiencies and mental and physical health challenges. When a person is recovering from an eating disorder or trying to break disordered eating habits, they generally try to replace disordered practices with healthy eating habits. 

Healthy eating habits may include eating breakfast, lunch, and dinner every day, eating meals that contain protein, complex carbohydrates, and vegetables, and eating when a person feels hungry, among other practices.

A fear of gaining weight and eating disorders

A fear of gaining weight often underlies common eating disorders. Most notably, a fear of gaining weight is thought to drive behaviors in anorexia nervosa and bulimia nervosa. A fear of gaining weight can also be present in OSFED disorders that involve restricting food or engaging in purging or other compensatory behaviors.

Signs of a fear of gaining weight

Knowing that a fear of gaining weight is present in many eating disorders could help a person become more aware of eating disorder warning signs. When a person has an immense fear of gaining weight, that could indicate they have or are at risk of developing anorexia nervosa, bulimia nervosa, or OSFED. 

Signs of a fear of gaining weight often overlap with other eating disorder signs and may include a preoccupation with one's weight or size, undereating, avoidance of certain foods or categories of food, and compensatory behaviors, like vomiting, taking laxatives, or over-exercising.

Eating disorder treatment

Research suggests that people who receive treatment for eating disorders usually have better outcomes than those who don't receive treatment. Recovery from an eating disorder is not always a linear process. A person may see symptoms gradually fade and then eventually enter remission, during which time they may no longer qualify for an eating disorder diagnosis.

However, an external event may eventually trigger the eating disorder to reoccur, which is usually referred to as a relapse. A person may go through multiple remissions and relapses before recovering for good. Different eating disorders can have different recovery rates, and up to 60% of people with an eating disorder may eventually recover. 

Eating disorder treatment types

Eating disorder treatment can be a complex process. Instead of a singular treatment, people may benefit from receiving multiple types of treatment at once. Eating disorder treatments may include the following:

  • Education and training
  • Family therapy
  • Individual therapy
  • Group therapy 
  • Peer support or support groups
  • Dietary programs or dietitian sessions
  • Exercise programs or personal training
  • Medication
  • Virtual reality or other digital simulation programs

Eating disorder therapy

People with an eating disorder or disordered eating habits may want to pursue therapy. Remote therapy could be a uniquely appealing option because of the comfort it may provide. With remote therapy, a person doesn't have to go in public or travel anywhere to meet with a therapist. Instead, they can meet with a therapist virtually using a digital device and wi-fi, connecting through video chats, phone calls, or online chat. BetterHelp is a platform that can connect people with remote therapists, often within 48 hours.

Research on therapy for different types of eating disorders

Multiple types of therapy for eating disorders exist. The type of therapy a person pursues may depend on the type of eating disorder they have. Authors of a systematic meta-review of meta-analyses on eating disorder treatments concluded that family-based therapy is the most evidence-based treatment for anorexia nervosa, and cognitive behavioral therapy (CBT) is the most evidence-based treatment for bulimia nervosa. Other types of therapy were also found to benefit people with these and other eating disorders.

In addition, research increasingly supports the use of online therapy for eating disorder treatment. According to a 2023 study, online therapy may effectively treat individuals with eating disorders and reduce symptoms of co-occurring conditions like depression.

Takeaway

Eating disorders can negatively impact a person's life and health, so identifying and treating them as early as possible can be crucial. Educating parents, doctors, teachers, coaches, friends, and peers on the signs and symptoms of eating disorders may help with early identification. Whether a person is diagnosed with an eating disorder or simply displays disordered eating habits, online or in-person talk therapy is one evidence-based treatment option.
