Obesity is a serious health concern that severely decreases the quality of life for many people. The practice of an eating disorder can be viewed as a survival mechanism. Just as an alcoholic uses alcohol to cope, a person with an eating disorder can use eating, purging or restricting to deal with their problems. Some of the underlying issues that are associated with an eating disorder include low self-esteem, depression, feelings of loss of control, feelings of worthlessness, identity concerns, family communication problems and an inability to cope with emotions. The practice of an eating disorder may be an expression of something that the eating disordered individual has found no other way of expressing.
