When calcium levels are only slightly low, there may be no symptoms. However, as the condition worsens, some symptoms that can develop are cramps in leg or back muscles, changes in hair texture and skin changes. With the progression of time, the symptoms are more severe and can include memory problems, depression and other brain-related symptoms. In very severe cases of low calcium, people can experience muscle spasms and heart problems, relates Merck Manuals.
Depending on the stage of this condition, which is called hypocalcemia, many other symptoms are possible, such as seizures and numbness or a tingling sensation in body areas that include the feet, hands and lips, explains MedicineNet. Hypocalcemia can have different causes, including problems with the parathyroid gland, certain medications, not getting sufficient amounts of calcium through diet or supplementation and different medical conditions, informs Merck Manuals. The treatment for hypocalcemia involves taking calcium supplements.
Calcium is a mineral needed by the body for strong bones and the proper functioning of muscles and the heart. A calcium deficiency can lead to an abnormal heart rhythm.
To avoid a calcium deficiency, people should get an adequate intake either through food or supplementation. The daily recommended amount of calcium people should take can vary by age. For example, people between the ages of 19 and 50 should get about 1000 mg. per day of calcium either through diet or supplementation according to guidelines set by the Institute of Medicine, states WebMD.
