Anorexia Nervosa: Symptoms, Causes, Diagnosis, Treatment and Prevention

Anorexia Nervosa is a severe eating disorder characterized by an intense fear of gaining weight and a distorted body image. The individuals suffering from this condition usually restrict their food intake drastically, which leads to a significantly low body weight. However, there's more to Anorexia Nervosa than just dieting and weight loss. It's a complex mental health condition that requires comprehensive treatment.

Symptoms of Anorexia Nervosa

Anorexia Nervosa symptoms can be physical, emotional, and behavioral. Some of the most common symptoms include:

  • Extreme weight loss or not making expected developmental weight gains
  • Thin appearance
  • Insomnia
  • Intense fear of gaining weight
  • Distorted body image, self-esteem overly related to body image
  • Denial of the seriousness of low body weight
  • Preoccupation with food, dieting, and body size

Causes of Anorexia Nervosa

Anorexia Nervosa, like other eating disorders, is likely caused by a complex interplay of genetic, biological, behavioral, psychological, and social factors.

Genetics: Some people may have a genetic tendency toward perfectionism, sensitivity, and perseverance — all traits associated with anorexia.

Biological: Certain biological factors, like changes in brain chemicals, may contribute to the development of anorexia.

Sociocultural factors: Western societal emphasis on thinness can lead to the development of eating disorders.

Psychological and emotional health: People with anorexia may have psychological and emotional characteristics that contribute to anorexia, such as perfectionism, anxiety, and negative self-esteem.

Diagnosis of Anorexia Nervosa

Anorexia Nervosa is typically diagnosed through a combination of physical examinations, psychological evaluations, and detailed questioning about eating habits. Doctors may also order laboratory tests to rule out other potential causes of weight loss and evaluate the impact of the disorder on the patient's health.

Treatment of Anorexia Nervosa

Treating Anorexia Nervosa involves a multi-faceted approach. A team of professionals, including a psychiatrist, a dietitian, and a therapist, collaborates to create an individualized treatment plan. This typically involves:

Medical Treatment: Medical care aims to stabilize and address serious health issues, such as malnutrition, heart conditions, or osteoporosis.

Therapy: Psychotherapy, such as cognitive-behavioral therapy (CBT) or family-based treatment, can help address the underlying psychological issues associated with anorexia.

Nutritional Counseling: Dietitians and nutritionists can help restore healthy eating patterns and promote a healthy relationship with food.

Prevention of Anorexia Nervosa

Preventing Anorexia Nervosa may not always be possible. However, fostering a healthy body image in children and teenagers, and promoting safe and healthy ways of eating and exercising can help. Also, early intervention can help reduce the severity of anorexia if it develops.


Anorexia Nervosa is a complex and severe eating disorder that requires early detection, comprehensive treatment, and continuous monitoring. It is essential to seek help if you or a loved one show signs of anorexia to avoid potential life-threatening complications.
