Anorexia Nervosa — is an eating disorder characterized by abnormally low body weight, an intense fear of gaining weight and a distorted perception of weight. People with anorexia place a high value on controlling their weight and shape, using extreme efforts that tend to significantly interfere with their lives.
Anorexia, like other eating disorders, can take over your life and can be very difficult to overcome. But with treatment, you can gain a better sense of who you are, return to healthier eating habits and reverse some of anorexia’s serious complications.

Causes:
The exact cause of anorexia is unknown. As with many diseases, it’s probably a combination of biological, psychological and environmental factors.
- Biological. Although it’s not yet clear which genes are involved, there may be genetic changes that make some people at higher risk of developing anorexia. Some people may have a genetic tendency toward perfectionism, sensitivity and perseverance — all traits associated with anorexia.
- Psychological. Some people with anorexia may have obsessive-compulsive personality traits that make it easier to stick to strict diets and forgo food despite being hungry. They may have an extreme drive for perfectionism, which causes them to think they’re never thin enough. And they may have high levels of anxiety and engage in restrictive eating to reduce it.
- Environmental. Modern Western culture emphasizes thinness. Success and worth are often equated with being thin. Peer pressure may help fuel the desire to be thin, particularly among young girls.
Complications of anorexia include:
- Anaemia
- Heart problems, such as mitral valve prolapse, abnormal heart rhythms or heart failure
- Bone loss (osteoporosis), increasing the risk of fractures
- Loss of muscle
- In females, absence of a period
- In males, decreased testosterone
- Gastrointestinal problems, such as constipation, bloating or nausea
- Electrolyte abnormalities, such as low blood potassium, sodium and chloride
- Kidney problem
In addition to the host of physical complications, people with anorexia also commonly have other mental health disorders as well. They may include:
- Depression, anxiety and other mood disorders
- Personality disorders
- Obsessive-compulsive disorders
- Alcohol and substance misuse
- Self-injury, suicidal thoughts or suicide attempts
Prevention:
If you notice that a family member or friend has low self-esteem, severe dieting habits and dissatisfaction with appearance, consider talking to him or her about these issues. Although you may not be able to prevent an eating disorder from developing, you can talk about healthier behaviour or treatment options. You can also help them get in touch with therapy.
