Hypocalcemia is a medical condition characterized by low levels of calcium in the blood. Calcium is essential for many bodily functions, including muscle contractions, nerve signaling, and bone health. When calcium levels drop too low, it can lead to symptoms such as muscle cramps, tingling sensations, and even seizures in severe cases. Several factors can contribute to hypocalcemia, including a deficiency in vitamin D, certain medications, or underlying health issues like kidney disease. Treatment often involves dietary changes, supplements, or medications to restore normal calcium levels and prevent complications. Regular monitoring is important for those at risk.
