high calcium (Ca2+) level in the blood serum

Hypercalcemia is too much calcium in the body. It is usually caused by either cancer or parathyroid disease. If hypercalcemia is severe, it may cause changes in mental status. Other symptoms can include nausea, abdominal pain, constipation, and thirst.[1] Hypercalcemia can be asscociated with Sarcoidosis[2] or Tuberculosis.
