The symptoms of anorexia nervosa and bulimia nervosa overlap at a large extent. Both are eating disorders in which the individual, affected by any of those, tries to lose weight in unhealthy manner. But there are some key differences between both the disorders.

People suffering with anorexia tend to reduce their food intake to lose weight. It includes extreme dieting and in some cases people stop eating or eat minimal.
