Anorexia nervosa is a serious eating disorder characterized by self-imposed starvation, extreme weight loss, and an intense fear of gaining weight. This condition affects millions of people worldwide, particularly adolescents and young adults, and can have devastating effects on physical and mental health. The symptoms of anorexia often develop gradually, making them difficult to recognize at first. Awareness of these symptoms is critical for early intervention, proper treatment, and support. Understanding the physical, emotional, and behavioral signs of anorexia can help families, educators, and healthcare providers identify the condition before it leads to severe complications.
Physical Symptoms of Anorexia
Significant Weight Loss
One of the most visible symptoms of anorexia is rapid and severe weight loss. Individuals may appear extremely thin compared to their age and height, often striving to maintain a body weight well below what is considered healthy. This weight loss results from strict dieting, excessive exercise, or other methods of calorie restriction.
Changes in Skin and Hair
Physical changes often accompany weight loss. People with anorexia may develop dry, flaky skin, brittle nails, and fine, soft hair called lanugo on their face, arms, or back. Hair thinning and hair loss on the scalp are also common, reflecting malnutrition and hormonal imbalances caused by prolonged calorie restriction.
Gastrointestinal Issues
Chronic undernourishment can lead to digestive problems such as bloating, constipation, abdominal pain, and slowed digestion. These symptoms result from reduced intake of essential nutrients, dehydration, and decreased gastrointestinal motility, making eating even more challenging for individuals with anorexia.
Fatigue and Weakness
Severe energy depletion is common in anorexia. Individuals often experience constant fatigue, muscle weakness, dizziness, and difficulty concentrating. These symptoms are caused by inadequate caloric intake and the body’s struggle to maintain vital functions with insufficient fuel.
Heart and Bone Complications
Long-term anorexia can affect the cardiovascular system, leading to slow heart rate (bradycardia), low blood pressure, and an increased risk of heart failure. Bone density may also decrease, causing osteoporosis and increased susceptibility to fractures. These complications highlight the serious impact of anorexia on long-term physical health.
Behavioral Symptoms of Anorexia
Restrictive Eating Habits
Individuals with anorexia often engage in extreme dietary restrictions. They may avoid entire food groups, skip meals, or count calories obsessively. These behaviors are often paired with rigid rules about what, when, and how much to eat, demonstrating an unhealthy preoccupation with food and body weight.
Excessive Exercise
Excessive physical activity is a common behavioral symptom of anorexia. Some individuals use exercise as a method to burn calories and control weight. This behavior can become compulsive, continuing despite injury, illness, or fatigue, and it often contributes to further physical deterioration.
Ritualistic Eating Patterns
People with anorexia may develop ritualistic behaviors around food, such as cutting food into tiny pieces, eating very slowly, or hiding food. These behaviors reflect the psychological control exerted over eating and can signal the severity of the disorder.
Avoidance of Social Situations Involving Food
Anorexia often leads to social withdrawal, particularly in settings where food is present. Individuals may decline invitations to eat with family or friends, citing excuses to avoid meals. This social isolation can worsen mental health and reduce support from loved ones.
Psychological Symptoms of Anorexia
Intense Fear of Gaining Weight
A hallmark psychological symptom of anorexia is an overwhelming fear of gaining weight, even when underweight. This fear drives restrictive eating, over-exercising, and obsessive monitoring of body size and shape. It often dominates daily thoughts and decision-making.
Distorted Body Image
Individuals with anorexia may perceive themselves as overweight even when they are dangerously thin. This distorted body image fuels unhealthy behaviors, reinforces low self-esteem, and contributes to a cycle of self-starvation and psychological distress.
Perfectionism and Control
Anorexia is often linked to perfectionist tendencies and a strong desire for control. Individuals may set extremely high standards for themselves, including appearance and performance, and use food restriction as a way to exert control over their bodies and environment.
Anxiety and Depression
Many individuals with anorexia experience co-occurring mental health conditions such as anxiety, depression, and obsessive-compulsive behaviors. These psychological symptoms can exacerbate restrictive eating and make treatment more complex, highlighting the importance of comprehensive care.

Complications of Untreated Anorexia
Medical Complications
Untreated anorexia can lead to severe medical issues, including heart problems, electrolyte imbalances, kidney damage, and bone density loss. Malnutrition affects every organ system, making early recognition and treatment critical to prevent life-threatening consequences.
Mental Health Consequences
Chronic anorexia can exacerbate depression, anxiety, and social isolation. Persistent restrictive behaviors can also lead to obsessive-compulsive tendencies and significant impairment in daily functioning. Long-term psychological support is often required alongside nutritional rehabilitation.
Treatment and Support
Medical and Nutritional Care
Treatment typically involves a multidisciplinary approach, including medical monitoring, nutritional rehabilitation, and therapy. Healthcare providers work to restore healthy weight, correct nutritional deficiencies, and monitor vital signs and lab values to prevent complications.
Psychotherapy
Cognitive-behavioral therapy (CBT) and other forms of psychotherapy help individuals address distorted thoughts about food and body image. Therapy can also assist with coping strategies, emotional regulation, and addressing co-occurring mental health issues such as anxiety and depression.
Family Support and Education
Family involvement is crucial in supporting recovery from anorexia. Education about the disorder, encouragement of healthy eating habits, and creating a supportive environment can significantly improve treatment outcomes. Support groups also provide additional guidance and connection for both individuals and families.
The symptoms of anorexia encompass physical, behavioral, and psychological domains, reflecting the complex nature of this eating disorder. Early recognition of warning signs, including extreme weight loss, restrictive eating habits, distorted body image, and obsessive thoughts about food, is essential for effective intervention. Comprehensive treatment, combining medical care, psychotherapy, nutritional support, and family involvement, can help individuals recover and restore health. Awareness and understanding of anorexia symptoms not only aid in early detection but also promote compassion and support for those affected, ultimately enhancing recovery and long-term well-being.
