The main function of calcium in the human body is muscle contraction. In order for the muscles to contract, calcium must enter the cells. If calcium is excessed in the blood, there is an excessive amount of passage into the cell and the muscles contract continuously. This also causes muscle aches.

However, the kidneys try to eliminate excess calcium in the blood. This causes damage to the kidney by exhausting it on the one hand, and on the other hand, it causes calcium to accumulate in the kidney and pave the way for the formation of stones or sand. However, the most important risk of calcium elevation in the blood is in the heart. The heart is a pump, and this pump works by contracting and relaxing the heart muscle. Too much calcium input to the heart muscle causes the heart to contract more frequently and uncontrollably, just like other muscles. This can result in heart failure and arrhythmia in the heart. Both present a life hazard.
