#5 Extreme thirst, frequent urination, and heart problems
Urination is another side effect of hypercalcemia. The more calcium in your circulation, the harder your kidneys have to struggle to filter it out, resulting in more urine. This, in turn, causes chronic thirst and dehydration. You may even believe that you would never be able to satisfy your thirst.
Increased calcium levels can also cause cardiac issues, most often a fast or irregular pulse. Hypercalcemia can lead to severe cardiac difficulties, such as cardiac arrest or coma.
