A serious eating disorder characterized by an intense fear of gaining weight and a distorted body image, leading to self-starvation and excessive weight loss.
She was diagnosed with anorexia after her friends noticed her drastic weight loss and refusal to eat.
Anorexia is formed from "an-" (meaning without) and "orexis" (from Greek "orexis", meaning appetite or desire). The word describes a condition characterized by a lack of appetite or desire to eat.
Think of 'without' ('an-') appetite ('orexis') to remember that anorexia refers to a lack of desire to eat.
