Which symptoms are commonly associated with hypercalcemia of malignancy?

• A. Confusion, lethargy, nausea, vomiting, constipation
• B. Diarrhea and rash
• C. Cough and chest pain
• D. Frequent urination only

Answer: (A)

Hypercalcemia from malignancy disrupts nervous system signaling and smooth muscle function. Elevated calcium levels slow brain activity, leading to confusion and lethargy, and they also decrease gastrointestinal motility, causing nausea, vomiting, and constipation. This mix of neurocognitive and GI symptoms is a classic presentation of hypercalcemia of malignancy, making it the most consistent and likely cluster of symptoms. Other options don’t fit this pattern: diarrhea with a rash isn’t the typical neuropsychiatric/GI combination seen with high calcium, cough and chest pain point to respiratory or thoracic issues, and frequent urination alone doesn’t capture the broader CNS and GI effects characteristic of hypercalcemia.
