10 Multiple Myeloma Symptoms
Symptom #4: Hypercalcemia
Hypercalcemia refers to the higher than normal levels of calcium in the blood. Symptoms of hypercalcemia include confusion, abdominal pain, depression, bone pain, kidney stones, weakness, and abnormal heart rhythm.
While most cases of hypercalcemia are due to cancer or hyperparathyroidism, other causes include tuberculosis, sarcoidosis, multiple endocrine neoplasia, Paget disease, familial hypocalciuric hypercalcemia, vitamin D toxicity, and many more. In multiple myeloma, the breakdown of bone results in the release of calcium into the blood. This causes hypercalcemia.
