Anorexia nervosa and bulimia nervosa are both eating disorders but are not solely distinguished by fasting or purging. Anorexia nervosa involves restriction of energy intake leading to significantly low body weight, while bulimia nervosa involves episodes of binge eating followed by compensatory behaviors such as purging. Purging can occur in both disorders, but the key difference lies in the presence of binge eating in bulimia and the significant weight loss and fear of gaining weight in anorexia.
