Anorexia
Anorexia, aka anorexia nervosa, is an eating disorder where an individual purposefully starves or under-eats in the false belief that they are overweight and/or have an unattractive body shape (see also Body Dysmorphic Disorder).
Anorexia most commonly affects girls and women, although it has become more common in boys and men in recent years. On average, the condition first develops at around the age of 16 to 17.
The symptoms of anorexia can lead to serious health problems if the condition is left untreated.
