Which symptom is associated with hypocalcemia?

• A. Bradycardia
• B. Polyuria
• C. Perioral numbness
• D. Hypertension

Answer: (C)

Hypocalcemia, or low serum calcium levels, can present with various clinical symptoms, one of which is perioral numbness. This symptom arises due to the neuromuscular excitability that occurs when calcium levels drop, affecting nerve conduction and muscle function. The tingling or numbness around the mouth and in the extremities, a phenomenon known as "paresthesia," is particularly notable and occurs as a result of increased neuronal excitability related to diminished calcium levels. In addition to perioral numbness, other symptoms of hypocalcemia can include muscle cramps, spasms, and potentially seizures in severe cases. The relationship between calcium levels and neuromuscular function is crucial, as calcium plays a vital role in neurotransmitter release and muscle contraction mechanisms. Therefore, perioral numbness is a classic sign that can help identify hypocalcemia, making it the correct answer.
