1. What Is Anorexia Nervosa?

Anorexia nervosa is an eating disorder and a mental health condition marked by:

• Persistent restriction of food intake
• An overwhelming fear of gaining weight
• A skewed perception of one’s own body size or shape

Unlike dieting or fasting, anorexia is a psychological illness where the person’s self-worth is strongly tied to their weight and appearance. Individuals with anorexia often see themselves as overweight, even when they are dangerously underweight.

2. Types of Anorexia

There are two main subtypes of anorexia nervosa:

Restricting Type

This is the most common form of anorexia. Individuals severely limit the amount of food they eat, often eliminating entire food groups. They may also engage in excessive exercise to burn calories.

Binge-Eating/Purging Type

In this subtype, individuals may engage in episodes of binge eating (consuming large amounts of food in a short time), followed by purging behaviors such as vomiting, misuse of laxatives, diuretics, or enemas.

3. Signs and Symptoms

Anorexia symptoms can be divided into physical, behavioral, and emotional signs:

Physical Signs

• Significant weight loss or failure to gain expected weight in adolescents
• Fatigue, dizziness, or fainting
• Cold intolerance (feeling cold all the time)
• Hair thinning or hair loss
• Irregular or absent menstrual cycles
• Gastrointestinal problems (constipation, bloating)
• Dry or yellowish skin
• Lanugo (fine hair growth on the body)

Behavioral Signs

• Skipping meals or eating tiny portions
• Avoiding food-related social events
• Obsessive calorie counting
• Excessive exercise
• Lying about food intake

Emotional and Cognitive Symptoms

• Distorted body image
• Intense fear of weight gain
• Low self-esteem
• Anxiety or depression
• Perfectionism or obsessive tendencies

4. Psychological and Physical Effects

Anorexia nervosa affects every organ in the body. Prolonged malnutrition and extreme weight loss can cause:

• Brain shrinkage and cognitive impairment
• Heart rhythm disturbances and heart failure
• Osteopenia and osteoporosis (bone weakening)
• Kidney and liver damage
• Infertility
• Muscle loss and weakness

Psychologically, the disorder reinforces a cycle of obsession and compulsion around food and body image, increasing the risk of severe anxiety, depression, and suicide.

5. Causes and Risk Factors

Anorexia develops due to a complex mix of genetic, psychological, social, and environmental factors.

Biological Factors

• Genetics: A family history of eating disorders or mental illness can increase risk.
• Neurobiology: Imbalances in brain chemicals like serotonin and dopamine can affect appetite and mood regulation.

Psychological Factors

• Perfectionism and high self-criticism
• Low self-esteem
• Difficulty coping with stress
• Obsessive-compulsive tendencies

Social and Cultural Influences

• Societal emphasis on thinness and beauty standards
• Peer pressure or bullying
• Media portrayal of unrealistic body ideals
• Family dynamics and trauma history

6. Diagnosis

Early diagnosis is a key to effective treatment. A medical professional may use:

• Physical exams (weight, BMI, vital signs)
• Lab tests (electrolytes, liver/kidney function)
• Psychological evaluation (interviews, questionnaires)
• Criteria from the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders)

7. Treatment Approaches

Anorexia nervosa treatment requires a multidisciplinary approach, often including:

Medical Care

To address immediate health risks such as malnutrition, dehydration, and electrolyte imbalance.

Nutritional Counseling

Registered dietitians help individuals gradually restore a healthy eating pattern and repair their relationship with food.

Psychotherapy

• Cognitive Behavioral Therapy (CBT): Focuses on challenging and changing unhelpful thoughts about food and body image.
• Family-Based Therapy (FBT): Especially effective for adolescents, involving the whole family in recovery.
• Dialectical Behavior Therapy (DBT): Helps with emotional regulation.

Medication

While no drugs cure anorexia, antidepressants or antipsychotics may help manage underlying anxiety, depression, or obsessive behaviors.

8. Nutrition and Recovery

Recovery isn’t just about gaining weight. It’s about learning to eat intuitively, trust your body, and adopt long-term habits that support physical and emotional well-being.

Goals of nutritional recovery include:

• Re-feeding the body gradually and safely
• Normalizing eating habits
• Addressing food fears and rituals
• Educating about balanced nutrition

9. Complications and Long-Term Impact

Without treatment, anorexia can be fatal. Some of the long-term complications include:

• Chronic organ damage
• Loss of bone density
• Infertility and hormonal imbalances
• Increased risk of cardiovascular disease
• Long-term mental health issues
• Social isolation and poor quality of life

10. Supporting a Loved One with Anorexia

Helping someone with anorexia can be emotionally challenging. Here’s how to provide support:

• Approach them with compassion, not judgment.
• Focus on their feelings, not just their eating habits or appearance.
• Encourage professional treatment and offer to help find resources.
• Set healthy boundaries and take care of your own well-being.

11. Preventing Eating Disorders

Prevention starts with awareness and education:

• Promote body positivity and self-acceptance.
• Model healthy eating behaviors at home.
• Challenge societal beauty standards and media stereotypes.
• Educate children and teens about nutrition and self-worth.

12. Living With and Beyond Anorexia

Recovery from anorexia is possible, but it’s often a long journey that requires continuous support and self-compassion. Individuals may face relapses, but ongoing therapy, support groups, and healthy routines can promote lasting healing.

Many people in recovery find strength in:

• Journaling and creative expression
• Practicing mindfulness and self-care
• Building a support network
• Celebrating small wins
