Dehydration
Another possible cause of hypercalcemia is severe dehydration. When your body does not take in sufficient fluids, there will be less water in the blood. As a result, it increases the buildup of calcium and other minerals in your bloodstreams. Fortunately, this problem only triggers mild cases and it can be resolved easily when you are hydrated sufficiently. Another factor that determines the level of severity would be the functions of your kidneys. People with kidney disease tend to suffer from more severe effects due to dehydration. [5]
