Anorexia vs Bulimia

Are you feeling confused about the difference between Anorexia and Bulimia? It can be tricky to know what the key distinctions are.

In this blog, we’ll explore the two eating disorders, so you have a better understanding of their differences. Discover what’s really behind each disorder and why it’s essential to get help.


Eating disorders are potentially harmful conditions that involve disordered eating patterns and severe disturbances in a person’s self-image. Anorexia nervosa and bulimia nervosa are the two most common types of eating disorders, but there are also many others. Although anorexia and bulimia share some similarities, they have several key differences. It is important to understand what these differences are to properly diagnose someone with an eating disorder.

Anorexia is defined as a refusal to maintain a healthy body weight, intense fear of gaining weight, distorted body image, and preoccupation with food or rigid diets, including the avoidance of certain foods even when hungry. Bulimia is defined as recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting or excessive exercise. While anorexics restrict their food intake to stay thin or lose weight, bulimics will binge eat large amounts of food before purging it out of their bodies through vomiting or exercising excessively to burn off the calories they ate during their binges.

In addition to these differences between anorexia and bulimia, people with each disorder might also experience different psychological symptoms. Anorexic individuals typically display low self-esteem, anxiety about gaining weight, and depression due to poor nutrition or other factors related to restrictive diets. In contrast, people with bulimia might suffer from guilt about food restriction followed by binging; this could trigger feelings of self-loathing and shame related to the amount and type of food consumed during the binges. Symptoms exclusive to bulimia may include dental problems from repeated vomiting and digestive system upset due to frequent purging habits.

What is Anorexia?

Anorexia nervosa, commonly referred to simply as anorexia, is an eating disorder characterized by extreme and dangerous weight loss arising from abnormal eating behaviors and distorted body image. People with anorexia often severely restrict the amount of food they eat and become obsessive about the number of calories they consume. They may also over-exercise or engage in a variety of other activities to ensure that their food intake is as low as possible.

The primary symptom of anorexia nervosa is dramatic and dangerous physical weight loss due to the under-consumption of food or self-induced vomiting after consuming small amounts of food. As part of their disorder, people with anorexia have a persistent fear of becoming fat and may have difficulty recognizing their low body weight or perceiving themselves accurately in mirrors. They may also become preoccupied with food and begin using extreme tactics such as fasting, using diet pills or diuretics, or taking laxatives to control their weight.

In addition, people with the disorder often develop socially withdrawn habits that can be difficult for physicians to recognize in the early stages.

What is Bulimia?

Bulimia is a serious and potentially life-threatening eating disorder that is marked by a cycle of binge eating, followed by compensatory behaviors like vomiting, abusing laxatives, fasting, or excessive exercising. Those with bulimia often struggle with anxiety, depression, guilt, and shame. They tend to judge their self-worth based on their physical appearance and body size.

Bulimia is often characterized by secretive behavior and attempts to hide eating habits from others. Bulimics tend to go through periods of normal eating patterns followed by episodes of binging in which an excessive amount of food is consumed in a short period. Afterward, the individual may use extreme measures such as throwing up or taking laxatives to compensate for the binge eating episode. Unlike anorexia, those suffering from bulimia are usually at or slightly above their ideal weight.

Causes of Anorexia and Bulimia

There is no one single cause of anorexia or bulimia. Factors such as biology, genetics, psychology, and social environments all play a role in the development of these eating disorders.

Biological influences may include body image issues (related to the comparison with others), changes in hormones, or biological sensitivity to weight gain. Similarly, people with existing mental health conditions like depression, OCD, and anxiety may be more vulnerable to developing an eating disorder.

Family backgrounds can also have a significant influence on the development of anorexia or bulimia; for example, families that emphasize achievement over relationships and have difficulty expressing emotions may be more likely to pass this type of behavior onto their children. Social factors can include school-related stressors such as academic performance pressure from parents or peers; unrealistic expectations from parents about appearance; bullying; cultural pressures related to physical beauty; media messages about what is ‘normal’ for beauty standards (e.g., achieving the “body perfect”).

Regardless of how and why they develop, anorexia and bulimia are serious mental illnesses that require professional treatment and care. It is important to reassure those affected by either disorder that helps is available and recovery is possible – including supports such as therapy or counseling sessions, medication management if needed, and health promotion programs designed specifically for those struggling with eating disorders.

Symptoms of Anorexia and Bulimia

Anorexia and bulimia are two eating disorders that have symptoms in common, leading some people to confuse the two. The important distinction between them is the presence of a person’s underlying mentality about their body image and the unhealthy behaviors that result from those distorted thoughts and beliefs.

Anorexia symptoms include extreme weight loss, abstaining from food (or severely restriction food intake), feeling intensely negative about one’s body size or shape, intense fear of gaining weight, amenorrhea (no menstrual cycle in women), depression, anxiety, irritability as well as physical health problems such as fatigue, heart irregularities, and dehydration.

Bulimia symptoms include binging on food followed by compensatory strategies to prevent weight gain, such as vomiting or using laxatives or diuretics; feeling a lack of control around eating; feeling shame or guilt afterward; relying on appearance rather than health-oriented goals; having an unhealthy obsession with how many calories consumed daily; getting secret supplies of binge foods; engaging in excessive exercise; avoiding social situations where food may be present and physical problems like GI distress, dehydration, and electrolyte imbalance.

Treatment Options

While there are no “quick fixes” for anorexia or bulimia, treatment for both mental health disorders is available. Treatment typically focuses on helping the person learn healthier ways to cope with their feelings and find a sense of self-worth. Effective treatments involve specialized therapy, lifestyle changes, and positive reinforcement.

For anorexia, the goal of treatment is to achieve a healthy body weight while creating new attitudes and behaviors around food, diet, and exercise. Treatment may involve nutritional counseling that focuses on increasing caloric intake, setting realistic goals for restoring weight, and improving overall physical health. Therapists often use cognitive-behavioral techniques to help identify unhealthy thoughts connected to body image and other life stressors such as family relationships or academic challenges.

For bulimia, the goal of treatment is to reduce binge-eating episodes and eliminate purging behaviors such as vomiting, laxative abuse, or excessive exercise. The primary aim of treatment is not just weight gain but addressing underlying emotional issues such as low self-esteem or depression. Cognitive behavioral therapy (CBT) has proven successful in treating bulimia since it helps individuals change negative thought patterns while learning new skills that create a balanced approach to emotions and food. Dialectical behavioral therapy (DBT) can also be used to address mood swings between extreme diets or eating behaviors to get an individual back on track with a positive approach to nutrition.

Supportive dietary counseling is usually highly recommended in the form of shared meal plans that recognize both needs around nutrition AND hunger/fullness levels without rigid calorie restrictions or threats of punishment during times when cravings hit or lapses occur during eating disordered thinking spirals down into guilt-ridden cycles. Other recommended components include physical exercise regimens that are humanely tailored toward individual nutritional demands rather than obsessive-compulsive tendencies regarding burning off calories through extremes of physical activity duration schedules as parts of successful treatment advances along with family-based interventions when needed for more complete recovery support structures outside the clinic walls..

Prevention Strategies

Prevention is key when it comes to anorexia and bulimia. Establishing healthy eating habits, maintaining regular exercise, and improving self-esteem can all help prevent the onset of an eating disorder. Additionally, focusing on body acceptance, being mindful of emotional factors precipitating unhealthy behaviors, and receiving appropriate mental health treatment are all integral components of the prevention process.

Educators, healthcare providers, coaches, family members and other individuals who interact with those vulnerable to eating disorders should be proactive by teaching healthy body image and developing positive relationships with their loved ones. Those close to someone at risk for anorexia or bulimia should have open conversations about these issues and encourage support for those struggling with either disorder.

Parents should also be selective about what kinds of images their children view online or in television/movies as imbalanced images perpetuating a harmful notion that slim equates to beauty can dramatically harm an individual’s psyche over time. Above all else, promoting positive self-talk is essential in preventing the onset of both disorders; encouraging individuals to respect their bodies rather than subscribing to societal standards goes a long way in establishing a better body image overall.


On the surface, eating disorders such as anorexia and bulimia may appear to have similar symptoms and causes, but in reality, each disorder is unique in its way. Anorexia is characterized by a significant and intentional loss of weight through restrictive dieting and/or excessive exercise, while bulimia involves recurrent episodes of binge eating followed by compensatory behaviors such as purging or misuse of laxatives.

No matter who you are or your current state of health, it’s important to remember that help is available. If you feel like you are struggling with an eating disorder or are concerned about someone else who is, reaching out for professional help can be a critical first step toward recovery.

Eating disorders can be debilitating conditions, but it’s important to keep in mind that these conditions can be treated with the right support system in place.
