Which of the following are symptoms of anorexia?

The symptoms of anorexia nervosa include significant weight loss and changes in physical appearance, and cachexia and lanugo are key indicators of this disorder. Cachexia refers to a state of severe malnutrition and wasting that often results from prolonged starvation, leading to muscle and fat loss. This occurs when the body is not receiving adequate nutrition to sustain itself. Lanugo is the fine, soft hair that may develop on the body as the body attempts to insulate itself due to the loss of body fat and warmth associated with severe weight loss.

Both of these symptoms are direct consequences of the body's response to malnourishment and the physiological changes that occur in individuals with anorexia. Recognizing such symptoms is critical for healthcare professionals in diagnosing and treating the condition effectively.
