Which of the following is a symptom of hypocalcemia?

• A. Hypertension
• B. Headache
• C. Polyuria
• D. Anorexia

Answer: (D)

Low calcium levels raise neuromuscular excitability and can produce gastrointestinal symptoms such as reduced appetite. Among the options, anorexia is the symptom most commonly associated with hypocalcemia. Hypertension and headaches are nonspecific and not typical signs of low calcium, and polyuria is usually linked to diabetes, nephrogenic effects of hypercalcemia, or other conditions rather than hypocalcemia.
