Which of the following is a common cardiovascular sign in severe Anorexia Nervosa?

• A. Bradycardia
• B. Hypertension
• C. Tachycardia
• D. Hyperglycemia

Answer: (A)

In severe Anorexia Nervosa, the body conserves energy, leading to a slowed heart rate. This bradycardia is a common cardiovascular sign because starvation reduces metabolic demand, causes cardiac muscle atrophy, and increases parasympathetic (vagal) activity. As a result, the resting heart rate often falls below normal levels and can be accompanied by low blood pressure. This slower heart rate reflects the body's adaptation to malnutrition rather than acute stress.

Hypertension is not typical in this state because volume and metabolic demand are reduced. Tachycardia would suggest a compensatory response to factors like dehydration, electrolyte imbalance, fever, or refeeding, rather than the baseline state of severe starvation. Hyperglycemia is also not a characteristic feature; glucose levels may be normal or even low due to inadequate intake. Therefore, bradycardia best matches the usual cardiovascular pattern seen in severe anorexia nervosa.
