For students pursuing NEET PG preparation understanding psychiatric conditions like Anorexia Nervosa is crucial, especially in the context of internal medicine, psychiatry and community medicine. Anorexia Nervosa is a severe eating disorder marked by an intense fear of gaining weight and a distorted body image leading to restricted food intake and significant weight loss. It remains a frequently tested topic due to its rising incidence and complex multidisciplinary management.
What is Anorexia Nervosa?
Anorexia Nervosa is a psychiatric eating disorder characterized by self-imposed starvation, extreme weight loss and irrational fear of weight gain. Despite being underweight individuals with anorexia perceive themselves as overweight and go to great lengths to reduce their body weight.
Anorexia Common Symptoms
- Severe weight loss
- Intense fear of gaining weight
- Distorted body image
- Amenorrhea

- Brittle hair and nails
- Cold intolerance
- Gastrointestinal issues like constipation
- Excessive exercise or food rituals
Psychological signs may include depression, anxiety and obsessive behaviour related to food and body image.
Causes of Anorexia
Several factors contribute to the development of anorexia:
- Biological factors: Genetics, neurotransmitter imbalances (especially serotonin), and family history.
- Psychological factors: Low self-esteem, perfectionism, and obsessive-compulsive traits.
- Sociocultural factors: Societal pressure to be thin, media influence, and peer comparison.
Types of Anorexia Nervosa
- Restricted Type: Individuals lose weight primarily through fasting, dieting or excessive exercise without binge eating or purging.
- Binge-Eating/ Purging Type: Involves binge eating followed by purging behaviours such as vomiting or misuse of laxatives and diuretics.
Anorexia Treatment
Treatment involves a multidisciplinary approach:
1. Medical Stabilization
- Hospitalization may be required in cases of severe malnutrition, bradycardia, or electrolyte imbalance.
2. Nutritional Rehabilitation
- A structured meal plan to restore healthy body weight.
- Gradual refeeding under supervision to avoid refeeding syndrome.
3. Psychotherapy
- Cognitive Behavioral Therapy (CBT) is the cornerstone of treatment.
- Family-based therapy (especially in adolescents).
- Support groups and counselling.
4. Pharmacotherapy
- While no specific drug cures anorexia, SSRIs (like fluoxetine) may help manage associated depression or anxiety.
Understanding Anorexia Nervosa, its clinical presentation underlying causes and management strategies is important for students involved in NEET PG preparation. With early diagnosis and appropriate interventions, the prognosis can significantly improve although long-term follow-up and psychological support remain essential.
