What is Anorexia Nervosa?

Anorexia is one of the deadliest mental illnesses. Due to its complexity, this condition requires comprehensive anorexia treatment from experienced eating disorder experts. Here at Eating Recovery Center (ERC), we offer a multidisciplinary treatment approach including medical and psychiatric stabilization, nutritional intervention and psychological support.

Symptoms & Warning Signs of Anorexia Nervosa

One of the most common misconceptions about anorexia nervosa is that sufferers are underweight, which is not always the case. In many instances, a patient with anorexia may appear to be healthy when they are malnourished. That’s why it’s important to understand all the warning signs and symptoms of anorexia

What Causes Anorexia Nervosa?

Anorexia is a bio-psycho-social illness, meaning that biological, psychological and sociocultural aspects contribute to the development of the illness. This means that anorexia – or any eating disorder, for that matter – is not a choice. There are clear causes of anorexia that individuals need to be aware of.
