Anorexia nervosa, often called anorexia, is a serious but treatable eating disorder. It involves extreme restriction of food, intense fear of gaining weight, and a distorted body image. People with anorexia may see themselves as overweight even when they are underweight or losing weight
It is not simply about food or appearance. The condition affects the brain, behavior, and physical health, and it can become life-threatening if not treated.
Key Characteristics
People with anorexia typically:
- Have very low body weight or fail to gain expected weight
- Fear weight gain intensely
- Constantly think about food, weight, or body shape
- Use extreme methods to lose weight or prevent weight gain
These behaviors are driven by psychological and biological factors, not personal choice.
Symptoms of Anorexia Nervosa
Physical Symptoms
Common physical signs include:
- Extreme weight loss
- Fatigue and weakness
- Dizziness or fainting
- Dry skin and hair loss
- Feeling cold often
- Irregular heart rhythms

Some people may also binge and purge, meaning they eat large amounts and then try to eliminate the food through vomiting or laxatives.
Causes of Anorexia
The exact cause is unknown, but it usually involves a mix of factors:
- Genetics – inherited traits may increase risk
- Mental health – perfectionism, anxiety, or obsessive traits
- Environment – social pressure to be thin, media influence
These factors interact, making the disorder complex and difficult to overcome.
Who is at Risk?
Risk factors include:
- Teenagers and young adults
- Family history of eating disorders
- History of dieting or weight-related bullying
- Major life changes (stress, loss, transitions)
Although more common in teens, anorexia can affect people of any age, gender, or background.
Complications
Anorexia can affect nearly every organ in the body. Serious complications include:
- Heart problems (including fatal arrhythmias)
- Bone loss (osteoporosis)
- Muscle loss
- Kidney problems
- Hormonal imbalance
- Severe malnutrition
It also increases the risk of:
- Depression and anxiety
- Substance misuse
- Self-harm or suicide
In severe cases, it can be fatal if not treated early.
When to Seek Help
Seek medical help if you or someone else has:
- Rapid or extreme weight loss
- Fear of eating or gaining weight
- Skipping meals frequently
- Physical weakness or fainting
Early treatment greatly improves recovery outcomes.
Treatment and Recovery
Anorexia is treatable, and recovery is possible.
Treatment usually includes:
- Medical care to restore weight and health
- Psychological therapy (such as counseling)
- Nutritional support and education
- Family support and monitoring
With proper care, many people regain a healthy weight, rebuild a balanced relationship with food, and recover mentally and physically.
Key Takeaway
Anorexia nervosa is a serious medical and psychological condition, not a lifestyle choice. It affects both the body and the mind. However, with early intervention and the right support, recovery is achievable and lives can be restored.
