Eating disorders don’t always look the way people expect. Early warning signs can appear in someone’s relationship with food, exercise, body image, emotions, or social life, sometimes long before noticeable physical changes occur.
Recognizing these changes can help individuals and families identify when additional support may be needed. Below are 15 possible early signs of eating disorders, along with important considerations for understanding them. No single behavior confirms an eating disorder, but persistent or concerning patterns deserve attention.
The National Institute of Mental Health (NIMH) provides additional information about eating disorder symptoms, risk factors, and treatment options.
- Declining Physical Health
One of the most visible indicators of an eating disorder is a decline in physical health. This might manifest as hair loss, acne, worn-down tooth enamel, bad breath, chronic exhaustion, low blood pressure, and irregular menstrual cycles. These physical signs can arise due to malnutrition, dehydration, or behaviors like purging. Therefore, it is essential to pay close attention to any significant changes in physical health. Recognizing these early signs of eating disorders can help you save yourself or a loved one.
- Poor Emotional Health
Eating disorders are deeply intertwined with emotional health, as they affect the mind, body, and soul. Many individuals with eating disorders experience co-occurring mental health conditions such as anxiety, depression, and obsessive-compulsive disorder. They may appear overwhelmed, irritable, or detached. In addition, these emotional challenges can exacerbate the eating disorder, making it harder for individuals to seek help or acknowledge their struggles. Early signs of eating disorders often show up emotionally as well as physically. According to the National Institute of Mental Health, eating disorders can co-occur with mental health conditions such as depression, anxiety, and substance use disorders.
- Body Dissatisfaction
A distorted body image and intense dissatisfaction with one’s physical appearance often serve as precursors to eating disorders. Those affected may obsess over perceived flaws, frequently check their reflection, or avoid mirrors altogether. Moreover, low self-esteem can amplify these concerns, creating a cycle of negative self-talk and unhealthy behaviors.
- Avoiding Check-Ins with Healthcare Providers
Eating disorders thrive in secrecy. Individuals may skip or avoid routine healthcare visits to conceal weight changes or other physical symptoms. Fear of being weighed or confronted about their eating habits or physical condition often drives this behavior. Consequently, this can delay necessary intervention and make it more challenging to address the eating disorder. Regular health checks with a healthcare provider are essential for spotting potential issues early and providing necessary support.
- Avoiding Certain Food Groups to Restrict Calories
A desire to lose weight can lead to a restrictive eating pattern, which is a common early sign of eating disorders. People might claim food intolerances or allergies, such as to gluten, dairy, or sugar, as a way to justify cutting out specific food groups. As a result, this behavior can be an initial step toward more dangerous patterns of restriction. Additionally, some individuals might turn to appetite suppressants in an attempt to control their food intake, further increasing the risk of medical complications.
- Wearing Baggy Clothes to Hide Body Changes
Many individuals with eating disorders wear oversized or baggy clothing to mask changes in their bodies. This practice can help them avoid questions or scrutiny from others about their weight or physical appearance, reinforcing their desire for secrecy. Furthermore, this coping mechanism can increase their sense of isolation and shame.
- Obsessive Focus on Food or Exercise
An unhealthy preoccupation with food or exercise is another red flag. This might look like counting every calorie, spending excessive time planning meals, or exercising excessively, even when tired or injured. Over time, this fixation can disrupt daily life and signal the development of disordered behaviors. Binge eating may also occur as a result of this obsession, followed by purging or extreme restriction.
- Social Withdrawal
Isolation from friends and family is a common early sign of an eating disorder. Social gatherings often involve food, and avoiding these situations can help individuals hide their struggles. In addition, this withdrawal can exacerbate feelings of loneliness and deepen the cycle of disordered eating. People may also shy away from social media, where they feel pressured by societal beauty standards and comparisons with others’ bodies. These early signs of eating disorders should be monitored carefully, as the sense of isolation can further harm one’s overall health.
- Going to the Bathroom After Meals
Frequent trips to the bathroom immediately after meals can indicate purging behaviors, such as self-induced vomiting. This is a key symptom of bulimia nervosa and binge/purge subtype anorexia nervosa. Eating disorders can occur at any body size, and someone’s weight or appearance may not reflect the severity of their symptoms. This is why behavioral and emotional warning signs deserve attention, even when there are no noticeable physical changes. For more information about the clinical characteristics and diagnostic criteria of eating disorders, refer to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR).
- Preoccupation with Weight or Appearance
People with eating disorders often become fixated on their weight or body shape, weighing themselves multiple times a day or obsessing over numbers on a scale. This preoccupation can overshadow other aspects of their life, contributing to a cycle of low self-esteem and distorted body image. Therefore, it is important to watch for any verbal expressions or actions that indicate an obsession with appearance.
- Rapid Weight Fluctuations
Sudden weight loss or gain is another potential warning sign. While not all individuals with eating disorders experience dramatic weight changes, any unexplained fluctuation should be taken seriously, especially if accompanied by other warning signs. For example, rapid weight changes in combination with physical or emotional symptoms can be an indicator of an eating disorder. Those experiencing dramatic weight loss may also show feelings of guilt or embarrassment, further amplifying their feelings of shame and complicating their relationship with food.
- Extreme Sensitivity to Comments About Appearance
Offhand remarks about someone’s appearance—whether positive or negative—can deeply affect all of us, and especially those at risk for eating disorders. They may become hypersensitive to perceived judgments, leading to heightened anxiety and efforts to control their appearance. Additionally, this sensitivity can fuel disordered behaviors as they try to “fix” what they perceive as flaws. People struggling with eating disorders may also avoid social situations where such comments are common, worsening their sense of isolation.
- Developing Ritualistic Eating Behaviors
Individuals may develop specific eating rituals, such as cutting food into tiny pieces, eating foods in a particular order, or avoiding certain textures. These habits can signal an underlying obsession with controlling their food intake. Consequently, these behaviors can become more entrenched and difficult to address over time, often exacerbating their unhealthy relationship with food.
- Expressing a Fear of Gaining Weight
Verbalizing an intense fear of weight gain or constantly seeking reassurance about their appearance can be a warning sign. This fear often stems from distorted body image and perpetuates restrictive eating or excessive exercise behaviors. In turn, this fear can lead to an unhealthy preoccupation with control over food and weight, increasing the higher risk of developing a full-blown eating disorder.
- Sudden Interest in Diet Trends or “Clean Eating”
Adopting extreme diet trends or obsessing over “clean eating” can sometimes mask disordered eating behaviors. While prioritizing health is positive, when it becomes rigid and obsessive, it may indicate the onset of an eating disorder. For instance, following extreme diet fads that cut out whole food groups could be a sign of emerging disordered eating patterns. The treatment process for eating disorders often involves addressing these distorted beliefs and the control issues associated with food.
Additional Eating Disorder Warning Signs to Be Aware Of
Eating disorders can present in many different ways, and the 15 signs outlined above aren’t an exhaustive list. Some warning signs are particularly easy to overlook because they resemble behaviors that are often normalized or even praised.
For additional insight, the National Alliance for Eating Disorders explores 11 subtle signs of eating disorders that are easy to miss, including behaviors that may not immediately raise concern.
What Should You Do If You Notice These Signs?
Recognizing potential signs of an eating disorder can be concerning, especially when you’re unsure how to approach the situation. Whether you’re noticing changes in yourself or someone you care about, early intervention can make a meaningful difference.
1. Start a conversation without focusing on appearance.
If you’re concerned about someone, approach the conversation with curiosity and compassion rather than assumptions. Focus on specific changes you’ve noticed, such as increased anxiety around meals, withdrawing from social activities, or becoming more rigid about food and exercise. Avoid commenting on weight, body size, or appearance.
2. Don’t wait for symptoms to become more severe.
Eating disorders can affect people of all body sizes, and someone doesn’t need to experience every warning sign to deserve support. Even subtle changes in eating behaviors, emotional well-being, or daily routines can be worth discussing with a qualified professional.
3. Seek an evaluation from a qualified healthcare professional.
A physician or mental health professional with eating disorder expertise can help assess symptoms and determine appropriate next steps. Depending on the individual’s needs, treatment may involve medical monitoring, therapy, nutrition counseling, and other forms of support. Find eating disorder specialized providers with this treatment directory.
4. Keep communication open and supportive.
If someone isn’t ready to discuss their concerns, continue offering support without pressure or judgment. Eating disorders can involve significant shame, secrecy, and ambivalence about change. Maintaining a supportive relationship while encouraging professional care can help create opportunities for future conversations.
