What serious consequence can anorexia nervosa cause?

Anorexia nervosa is a severe eating disorder characterized by a restricted intake of food, an intense fear of gaining weight, and a distorted body image. One of the most critical consequences of this disorder is the potential for the body to shut down. This occurs due to prolonged malnutrition and lack of essential nutrients, which can lead to organ failure. When the body is starved of necessary calories and nutrients, vital functions become compromised, and the organs may no longer operate effectively, leading to life-threatening conditions.

As the body relies on stored energy to function, when those stores become depleted, it can result in severe physiological stress, affecting the heart, lungs, kidneys, and other organs. This shutting down can manifest in various forms, including cessation of heart function, respiratory failure, and ultimately death if the person does not receive appropriate treatment.

The other options do not accurately reflect the serious health implications of anorexia nervosa. Increased physical stamina and enhanced cognitive function would not typically occur in the presence of such malnourishment, and a decrease in body temperature is a less severe symptom compared to the shutdown of bodily functions. Understanding these consequences underscores the critical need for intervention and support for individuals struggling with this condition.
