Chronic elevation of calcium with absent or mild symptoms often points to primary hyperparathyroidism or Familial hypocalciuric hypercalcemia. For those who has underlying malignancy, the cancers may be sufficiently severe to show up in history and examination to point towards the diagnosis with little laboratory investigations.
Like hypocalcemia, hypercalcemia can be non-severe and present with no symptoms, or it may be severe, with life-threatening symptoms. Hypercalcemia is most commonly caused by hyperparathyroidism and by malignancy, and less commonly by vitamin D intoxication, familial hypocalciuric hypercalcemia and by sarcoidosis. [2]
Furosemide can be used to treat hypercalcemia as it induces caliuresis (excreting calcium in the urine). Standard practice of adequate rehydration and electrolyte monitoring should be used to avoid alkalosis and renal insufficiency. [15] If kidney failure is advanced then treatment for that is required, namely chronic dialysis. [14]
Familial hypocalciuric hypercalcemia (FHH) is an inherited condition that can cause hypercalcemia, a serum calcium level typically above 10.2 mg/dL; although uncommon. [1] It is also known as familial benign hypocalciuric hypercalcemia (FBHH) where there is usually a family history of hypercalcemia which is mild, a urine calcium to creatinine ratio <0.01, and urine calcium <200 mg/day ...
Primary treatment of hypercalcemia consists of administering IV fluids. [3] If the hypercalcemia is severe and/or associated with cancer, it may be treated with bisphosphonates. [ 3 ] [ 14 ] For very severe cases, hemodialysis may be considered for rapid removal of calcium from the blood.
Metastatic calcification involves a systemic calcium excess imbalance, which can be caused by hypercalcemia, kidney failure, milk-alkali syndrome, lack or excess of other minerals, or other causes. Tumoral calcinosis
Primary hyperparathyroidism (or PHPT) is a medical condition where the parathyroid gland (or a benign tumor within it) produce excess amounts of parathyroid hormone (PTH). ). The symptoms of the condition relate to the resulting elevated serum calcium (hypercalcemia), which can cause digestive symptoms, kidney stones, psychiatric abnormalities, and bone dis
Though this condition is usually asymptomatic, if symptoms are present they are usually related to the causative process, (e.g. hypercalcemia). [4] Some of the symptoms that can happen are blood in the urine, fever and chills, nausea and vomiting, severe pain in the belly area, flanks of the back, groin, or testicles.
