Quick Summary

Hypocalcemia is a condition characterized by a deficiency of calcium in the blood. This can occur due to inadequate secretion or action of parathormone, a hormone crucial for regulating calcium levels.12

When calcium levels are low, it affects various bodily functions. Symptoms can include muscle cramping, twitching, and spasms, particularly in the hands and feet. In more severe cases, it can lead to convulsions, numbness, and tingling sensations. Chronic hypocalcemia may result in cataracts and calcification in the brain, potentially causing parkinsonism-like symptoms.2

Several factors can lead to hypocalcemia, including surgical removal of parathyroid glands, autoimmune disorders, magnesium deficiency, and genetic defects affecting calcium receptors. Other causes of low blood calcium include vitamin D deficiency, pancreatitis, and kidney failure. Severe calcium deficiency can manifest as tetany, involving numbness, tingling, and muscle spasms. Treatment typically involves calcium and vitamin D supplements.23
