Anorexia Nervosa and the Struggle for Thinness

pursue any method to prevent weight gain—regardless of the consequences. When this behavior turns into a disorder, it is known as anorexia nervosa.

In this article, we provide a comprehensive guide to anorexia nervosa, including its causes, symptoms, related conditions that lead to appetite loss, and how it can be treated—along with a breakdown of the harmful misconceptions surrounding it.

What Is Anorexia Nervosa?

Anorexia nervosa is an eating disorder in which a person either loses the desire to eat or deliberately avoids food to prevent weight gain. It affects approximately 9% of people worldwide.

Individuals with anorexia nervosa make extreme efforts to limit food intake to control calorie consumption. In some cases, they may purge after eating by inducing vomiting, using laxatives, diuretics, enemas, or performing excessive physical exercise.

This condition is especially common among adolescent girls and women in general, with a prevalence of about 0.3% of the population, or 1–2% of individuals.

Importantly, anorexia is not simply about food—it is a psychological issue, where the individual’s self-worth and identity become tied to their body weight.

What Are the Symptoms of Anorexia Nervosa?

Thinness varies from person to person, which can make it difficult to recognize the symptoms. Many of the physical signs of anorexia resemble those of starvation, while behavioral and emotional signs also emerge.

Physical Symptoms include:

1. Fatigue
2. Insomnia
3. Extreme thinness
4. Bluish fingers
5. Dry or yellowish skin
6. Dizziness or fainting
7. Brittle or thinning hair
8. Constipation
9. Cold intolerance
10. Low blood pressure
11. Swelling in limbs
12. Changes in blood composition
13. Significant weight loss or failure to gain weight with age
14. Tooth erosion from repeated vomiting
15. Irregular heartbeat

There are two types of anorexia nervosa:

1. Restrictive type – focused on limiting food intake severely.
2. Binge-purge type – involves eating large amounts followed by purging.

Behavioral and Psychological Symptoms include:

1. Excessive calorie restriction
2. Overexercising
3. Inducing vomiting or using weight-loss medications
4. Avoiding eating in public
5. Lying about food intake
6. Skipping meals or refusing to eat
7. Denying hunger
8. Making excuses to avoid meals
9. Weighing oneself excessively
10. Complaining about fat despite being underweight
11. Preparing elaborate meals for others without eating
12. Chewing food and spitting it out

What Causes Anorexia and Appetite Loss?

While the exact causes remain unknown, anorexia nervosa likely results from a combination of genetic, psychological, and environmental factors:

1. Genetics: Family history of perfectionism or persistence may increase the risk.
2. Environmental Factors: Media and cultural ideals that equate thinness with beauty raise the risk in adolescents and young adults.
3. Psychological Factors: Conditions like obsessive-compulsive disorder (OCD), stress, or anxiety can make it easier to develop strict eating patterns.

Risk Factors for Teens and Adolescents:

1. Life transitions: Events such as loss of a loved one, changing schools, or moving house may trigger anorexia.
2. Dieting and starvation: Starving the body affects brain chemicals, leading to mood changes and loss of appetite.
3. Family history: A relative with an eating disorder increases one’s risk.

What are Causes in Children and Infants?

In Children:

1. Developmental delays
2. Genetics
3. Neurochemical imbalances
4. Bullying about body image
5. Anxiety disorders
6. Growing up in overly strict or controlling households

In Infants (6–36 months):

Infants may refuse food as a means to assert independence or seek attention from the mother. This power struggle can lead to disrupted hunger cues and hinder growth.

How Is Anorexia Nervosa Diagnosed?

Since anorexia symptoms can mimic those of general hunger or other conditions, medical evaluation is essential. A diagnosis involves:

1. Physical Examination:
2. Vital signs
3. Height and weight
4. Skin and nail inspection
5. Blood pressure and heart rate
6. Abdominal examination
7. Lab Tests:
8. Blood work (liver and kidney function)
9. Urinalysis
10. Psychological Evaluation:
11. Assessing beliefs, behaviors, and emotional state
12. Imaging:
13. Bone density scans or ECG to detect heart irregularities

How Is Anorexia Nervosa Treated?

Treating anorexia requires collaboration between nutrition specialists and mental health professionals:

1. Dietitian’s Role: Create a tailored meal plan and calorie intake target to restore healthy weight.
2. Psychologist’s Role: Help manage the underlying psychological symptoms.

What are Treatment Challenges?

1. Fear of weight gain
2. Belief that treatment isn’t necessary
3. Misconception that anorexia is a lifestyle choice rather than a disorder

Treatment Options:

1. Psychotherapy

This includes:

1. Cognitive Behavioral Therapy (CBT):
2. Helps the patient rebuild a healthy eating pattern and challenge harmful beliefs about weight and body image.
3. Family-Based Therapy (FBT):
4. Especially important for teens, this helps parents support healthy eating and recovery.

2. At-Home Support

1. Avoid frequent body checking or weighing
2. Seek support from loved ones—don’t isolate
3. Take physician-recommended supplements like vitamin D or iron
4. Attend all therapy sessions and stick to treatment plans
