Answer

Complications of chronic hypocalcemia predominantly are those of bone disease. In addition, severe hypocalcemia may result in cardiovascular collapse, hypotension unresponsive to fluids and vasopressors, and dysrhythmias. Some patients may manifest digitalis insensitivity. Neurologic complications of hypocalcemia include acute seizures or tetany, basal ganglia calcification, parkinsonism, hemiballismus, and choreoathetosis. Although some patients with hypocalcemia may improve with treatment, the calcification typically is not reversible.
