Great explanation, thanks. Does anyone know why this patient is anemic though? Is there some link between hyperparathyroidism and anemia I am missing?

So I understand why parathyroid can be the right answer, but why couldn't kidney be correct? This is just my overthinking things, but renal cell carcinoma can present with PTHrp leading to hypercalcemia

@flvent2120 "Historically, medical practitioners expected a person to present with three findings. This classic triad[9] is 1: haematuria, which is when there is blood present in the urine, 2: flank pain, which is pain on the side of the body between the hip and ribs, and 3: an abdominal mass, similar to bloating but larger. (10-15% of patients)" -Wiki. I'm thinking the presentation would be different. Also male predominance, latter decades (6th and 7th).

Functional parathyroid adenomas can cause elevated parathyroid hormone (PTH), which results in hypercalcemia and hypophosphatemia. Hypercalcemia is characterized by the rhyming symptoms: stones (renal, biliary), bones (including bone pain to osteitis fibrosa cystica), groans (abdominal pain, n/v), thrones (polyuria, constipation), and psychiatric overtones (from depression to coma).
