What is Hypocalcemia?
Hypocalcemia occurs when calcium levels in the blood are lower than normal. Calcium is vital for many bodily functions, including muscle contractions and nerve signaling. Symptoms can vary from mild tingling to severe muscle spasms or even life-threatening conditions, depending on how low the calcium levels are.
Causes of Hypocalcemia
Hypocalcemia can result from several factors, such as vitamin D deficiency, hypoparathyroidism, or chronic kidney disease. Certain medications like bisphosphonates and conditions such as malabsorption syndromes can also lead to low calcium levels. Identifying the underlying cause is essential for effective treatment.

Symptoms of Hypocalcemia
Symptoms of hypocalcemia can range from mild to severe. Mild symptoms include tingling in the lips and fingers, while severe symptoms can involve muscle cramps, spasms, and seizures. In extreme cases, it can lead to cardiac issues like prolonged QT intervals, which require immediate medical attention.
