Hypercalcemia

Hypercalcemia is an elevated calcium level in the blood. Hypercalcemia can be asymptomatic in laboratory results, but high calcium levels are often an indicator of multiple myeloma. Hypercalcemia related to multiple myeloma is caused by the breakdown of bone which leads to the release of calcium into the blood. This can be a serious problem if appropriate treatment is not given immediately. Severe hypercalcemia can result in coma or cardiac arrest.

Symptoms of hypercalcemia include the following:

• Loss of appetite
• Increased thirst
• Increased urination
• Restlessness
• Difficulty in thinking or confusion
• Nausea and vomiting
