Our society places tremendous emphasis on being thin. Increasingly, women especially, are going to enormous lengths to lose weight and maintain their weight. But this obsession is also fuelling eating disorders, such as anorexia nervosa and bulimia nervosa.
Both of these eating disorders, if left untreated, can have very serious health consequences, but it is not always easy to intervene if you see a friend or family member suffering from either of these. Health24's Dietdoc gives advice in this regard.
