Acute hypocalcemia has neuromuscular tetany as hallmark symptom. Patients have rapid decrease in serum calcium and present with symptomatic hypocalcemia.
It is an emergency condition and requires immediate attention. Ca (IV) should be administered until signs and symptoms abate or until serum Ca levels rise.
Chronic hypocalcemia has asymptomatic mild hypocalcemia. Treatment is necessary to avoid long term complications. Oral Ca may be administered.
