Anorexia Nervosa

Anorexia Nervosa is a serious eating disorder that affects women and men of all ages. It is most common amongst girls and young women. It is characterised by an abnormally low body weight, intense fear of gaining weight and a distorted perception of body weight. The term Anorexia literally means "loss of appetite," although this is misleading as people with Anorexia Nervosa are often very hungry but deny themselves food. It is a serious illness which can be fatal, although full recovery is possible with the appropriate support and treatment. 


The causes of Anorexia vary from person to person. The disorder is not primarily about food and weight issues or about 'slimming'. As with all eating disorders, the psychological issues and emotional distress underlying the physical symptoms must be addressed for long-term recovery to be possible. The main factors which are believed to play a role in the development of Anorexia are;


Genetics and hormones might have an effect on the development of Anorexia Nervosa. Some evidence suggests a link between Anorexia and serotonin, a chemical produced in the brain.


Pressure from society to look thin may also contribute to the development of Anorexia Nervosa. Pictures on magazines and television can greatly influence young girls and spark the desire to be thin.


Someone with Obsessive Compulsive Disorder (OCD) might be more predisposed to maintaining the strict diet and exercise regimen that those with Anorexia Nervosa often maintain. People with OCD strive for perfection and may feel like they will never achieve it.


The physical signs and symptoms of Anorexia Nervosa are related to starvation, but the disorder also includes emotional and behaviour issues related to an unrealistic perception of body weight and an extremely strong fear of gaining weight or becoming fat.

There is no proven method to prevent Anorexia Nervosa but looking out for signs of the disorder can help with quick diagnosis, treatment, and recovery. If you find yourself or a loved one obsessing about weight, excessively exercising, or being dissatisfied with their appearance, you may want to seek professional help.

The disorder can be very difficult to overcome. But with the proper treatment, you can gain a better sense of who you are, return to healthier eating habits and reverse some of anorexia's serious complications.
