Anorexia nervosa generally leads to:

Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight and a distorted body image, leading to self-imposed starvation and excessive weight loss. Individuals with this condition typically adopt extreme dietary restrictions, resulting in significant and unhealthy weight loss. This weight loss can lead to severe health complications, including nutrient deficiencies, weakened bones, organ failure, and in severe cases, it can be life-threatening.

The other options do not accurately reflect the effects of anorexia nervosa. Weight gain to a healthy range and a balanced approach to food would contradict the behaviors associated with this disorder, as individuals suffering from anorexia are often unable to maintain healthy eating habits. Instead, their relationship with food is fraught with anxiety and unhealthy behaviors aimed at losing weight. Therefore, the significant and unhealthy weight loss associated with anorexia nervosa is the core characteristic of this disorder and accurately describes the primary consequence of the illness.
