Anorexia can impede normal growth in the young, adolescents and cause difficulties in concentration. People with anorexia nervosa may also experience mental health problems such as depression and increased risk of suicide.

The term anorexia nervosa was coined in 1873 by Sir William Gull, one of Queen Victoria's personal physicians. The history of anorexia nervosa begins with descriptions of religious fasting dating from the Hellenistic era and continuing into the medieval period. A number of well known historical figures, including Catherine of Siena and Mary, Queen of Scots are believed to have suffered from the condition. The medieval practice of self-starvation by women, including some young women, in the name of religious piety and purity also concerns anorexia nervosa; it is sometimes referred to as anorexia mirabilis. It was not until the late 19th century that anorexia nervosa was widely accepted by the medical profession as a recognized condition. Today many celebrities have come forward discussing their struggles with anorexia, increasing awareness of the disease.
