Which of the following is an EXCESSIVE indicator of thinness in Anorexia Nervosa?

Bradycardia, which is characterized by a slowed heart rate, is an excessive indicator of thinness in the context of Anorexia Nervosa. This condition occurs as the body responds to extreme weight loss and malnutrition. When the body is deprived of necessary nutrients and energy, it can lead to various physical complications, including the slowing down of heart rate as part of a broader physiological adaptation to preserve energy.

In individuals with Anorexia Nervosa, bradycardia is often accompanied by other signs of malnutrition and can indicate the severity of the individual's condition. It reflects not just the physical consequences of such restrictive eating behaviors, but also the overall impact on the body's functioning, including cardiovascular health.

In contrast, the other options provided do not align with excessive indicators of thinness. High blood pressure is generally not associated with Anorexia Nervosa; rather, it may be more common in individuals who are overweight or experiencing stress. Excessive energy levels would indicate that the body is still properly fueled, which contradicts the state of malnutrition evident in Anorexia Nervosa. Healthy bone mineral density typically indicates adequate nutritional status and is not consistent with the excessive loss of body weight and the risks associated with Anorexia Nervosa.
