What is Anorexia? Signs and Symptoms

Anorexia Nervosa is an eating disorder in which the sufferer severely restricts their food intake in order to lower their weight, or maintain a severely low weight. Anorexia Nervosa is characterised by a restrictive eating pattern with the purpose of constantly losing weight accompanied with a fear of gaining or maintaining their weight. There are many ways in which people with Anorexia may exhibit these behaviours such as: eating as little as possible, adhering to strict calorie limits, exercising excessively, and eating only certain types of foods or food groups.

Each case of the disorder is as unique as the individuals themselves, however the commonality is the pre-occupation with weight, body shape and size, with a particular focus on keeping it unhealthily low. Anorexia is not just a diet, it is an unhealthy pre-occupation with potentially life threatening consequences.

Some people with Anorexia, similarly to those with Bulimia, purge after they eat using methods such as: self-induced vomiting, laxatives, exercise or insulin abuse. However, unlike those with Bulimia, their weight is always very low, and their binges are more likely subjective in nature by comparison to those experiencing Bulimia Nervosa.


Simply having a low weight does not constitute a diagnosis of Anorexia in itself; Anorexia is a psychiatric disorder meaning that in order for a diagnosis to be made, there must be psychological aspects to the persons low weight and restrictive diet as well. There are a range of common traits, signs and symptoms of Anorexia Nervosa beyond maintaining a low weight that include psychological physiological and behavioural aspects.
