Anorexia nervosa and bulimia nervosa are both eating disorders, but the main difference is that individuals with anorexia have a tendency to skip meals, while individuals with bulimia go through a cycle of binging (overeating) followed by vomiting. People with anorexia are usually extremely underweight and with an unhealthy figure, while the physical appearance of people with bulimia can be “normal” or sometimes underweighted.
