Anorexia nervosa is a serious and deadly eating disorder that impacts at least 30 million people in the United States alone. But it can be a quiet disorder that slowly erodes people’s bodies, lives, relationships, and well-being. In most people minds, and unfortunately in clinical settings, anorexia nervosa is typically characterized by low body weight. But that can leave out a lot of people who need help. So, what are the signs of anorexia? And how can we tell when someone we love may be in need of treatment?
When most of us think of “anorexia” and the people who have it, there’s a certain image that tends to pop into our heads. We picture a young, white, middle-class woman. Maybe she does ballet. Sometimes, it’s gymnastics. She’s Type A, a good student, and probably has parents who expect a lot from her. She is thin to begin with, but as her eating disorder progresses, she become thinner and thinner. She’s Jennifer Jason Leigh in “The Best Little Girl in the World” or real-life anorexia sufferer Tracey Gold in “For the Love of Nancy.”
But that movie-of-the-week narrative is a problem. It leaves people behind.
Understanding the diagnostic criteria
Many clinicians, general practitioners and mental health professionals use the criteria in The Diagnostic and Statistical Manual of Mental Disorders (DSM) to determine whether a person has anorexia nervosa. The DSM is a publication of the American Psychiatric Association (APA). According to the DSM-5, a person must display the following behaviors or symptoms in order to be diagnosed with anorexia nervosa:
- Persistent restriction of energy intake leading to significantly low body weight (in context of what is minimally expected for age, sex, developmental trajectory, and physical health) .
- Either an intense fear of gaining weight or of becoming fat, or persistent behaviour that interferes with weight gain (even though significantly low weight).
- Disturbance in the way one’s body weight or shape is experienced, undue influence of body shape and weight on self-evaluation, or persistent lack of recognition of the seriousness of the current low body weight.
The issues with the DSM-5 criteria
While the DSM-5 has made progress in its definition of eating disorders, particularly in removing gender coding in the diagnostic criteria, this criteria still focuses on low body weight as a defining characteristic of anorexia nervosa. However, extreme restriction of food and starvation is not just dangerous for those with a thin frame. It’s dangerous regardless of size. Whether a person is very thin or very fat, starvation can have catastrophic effects on our health. Some of these complications include:
- Dizziness or fainting
- Impaired cognitive function, confusion
- Abnormal and dangerous heart rhythms, including slow heart rate, which is called bradycardia
- Electrolyte imbalances that can be dangerous for heart functioning
- Gastrointestinal problems
- Neurological problems, including temporary or permanent nerve damage
- Low blood pressure
The role of weight bias
Because anorexia nervosa is typically characterized by low body weight, people can miss symptoms and signs of anorexia in people who don’t meet that criteria. And we’re not just talking about friends and family. Medical professionals may dismiss, or even praise, behaviors that are associated with anorexia in patients who are on the higher end of the weight spectrum. But fat people can absolutely suffer from anorexia nervosa. And when it’s left undiagnosed and untreated, the results can be just as dangerous and deadly.
Age, class, race, and gender
The fact that anorexia nervosa is typically characterized as a disorder that exists primarily among young, white, middle-class woman is harmful. Because it isn’t true. While people that match that stereotype certainly suffer from anorexia, they aren’t the only ones, and there’s no evidence they suffer from anorexia or any other eating disorders more frequently. For instance, anorexia is something older people deal with as well, and we may be at higher risk for anorexia as we age. And it can affect people at any socioeconomic status too. One 10-year study found that there was an increased prevalence of extreme dieting, bingeing, and purging in households below the median income.
Most of the scientific studies that have been done focus on white women, so there’s simply a lack of data of about the prevalence of anorexia and other eating disorders in other racial groups. But what exists suggests that there is an equal or higher prevalence in Latinx women. Black women and men seem to have a lower prevalence, but often receive treatment later and may simply be under diagnosed.
Data about eating disorders in trans and non binary people is also lacking, but one study from 2015 showed that trans college students had a elevated rates of disordered eating.
It’s no wonder anorexia goes undiagnosed and untreated in many populations: Medicine and science has almost wholly focused on anorexia as something young, white, middle-class, cis women have. But it’s important that we not allow these institutional biases color our own thinking, especially if we are concerned about a loved one.
Signs a loved one may have anorexia nervosa
So, we aren’t necessarily going to know if a friend or relative has a low heart rate. What we can see and evaluate are their behaviors. And there are some common behaviors that can indicate anorexia, such as:
- Food avoidance, making excuses to not attend or participate in meals, skipping meals
- Fixation on the nutritional content of food
- Recording food intake (which includes using apps to track food consumption)
- Preparing meals or baking treats for others, without eating them
- Denial of hunger
- Cutting out entire food groups
- Food rituals, such as cutting food into very small bites, arranging food on the plate, eating food in a specific order, etc.
- Hoarding food
- Eating in secret, or fear of eating in front of others
- Mood disturbances, changes in personality, acting anxious or irritable
- Poor body image
- Low self-esteem
- Wearing clothing that is very loose, baggy, or many layers of clothing
- Obsessive exercise regimen, or the need to “burn off” any food consumed with exercise
- Becoming anxious or upset if unable to exercise, or exercising despite injuries
- Weight loss
- Fatigue, sluggishness, and slow reaction time
This list of signs a loved one may have anorexia nervosa is not definitive nor exhaustive, but it can be used to help identify whether anorexia is a potential cause if a friend or loved one is in distress.
Trauma and anorexia nervosa
Anorexia is typically characterized by physical and social symptoms, but other factors may be at play as well. There is strong evidence that anorexia nervosa and other eating disorders have a link to trauma. Past trauma, such as childhood abuse, or domestic violence, can put people at an increase risk. Life upheavals can also be a contributing factor — events like divorce or relationship changes, job loss, death of a spouse or loved one, and changing schools can help trigger an eating disorder (or cause a replace for a person in recovery).
While most of us are not able to diagnose an eating disorder in a loved one, we can show up to help them. We can start a conversation about their feelings and behavior, provide them with important resources and information, and show them love and support as they seek treatment and recover.
