Types of eating disorders
Regardless of type, eating disorders can cause serious mental and physical problems, and at their most severe, if not properly treated can even be life-threatening. Most people with eating disorders are females, but males can also have eating disorders. An exception is binge-eating disorder, which appears to affect almost as many men as women.
The major types of eating disorders

The most common form is defensive vomiting, sometimes called purging; fasting, the use of laxatives, enemas, diuretics, and over exercising are also common.
Bulimics are much more likely than non-bulimics to have an affective disorder, such as depression or general anxiety disorder
