Anorexia is most frequently a problem associated with an obsessive fear of obesity (anorexia nervosa). In general, anorexia refers to the loss of appetite, whether it be from drug disorders, depression, fever, alcoholic excess, bulimia, stomach distress or even from inappropriate drug usage (such as would befit a cocaine habit) and is generally treated as a psychological disorder. Making mealtimes pleasant and regular is one effective means of combating this disorder.
