Hypercalciuria

What is it?

Hypercalciuria refers to having high levels of calcium in the urine. It could be either idiopathic, meaning, with no underlying condition, or it could happen due to another condition. Hypercalciuria may be caused due to high calcium levels in the blood, over absorption of calcium in the gastrointestinal tract or from the bones or from urinary leakage. It is the most common cause for nephrolithiasis. Diagnosis is based upon findings from medical history and physical examination. Further evaluation may include urine test for calusion level or 24-hours urine collection test. Renal, blood pressure and bone assessment should be performed when hypercalciuria is diagnosed. Treatment depends on the underlying cause and may include calcium restriction in diet, high protein intake and use of thiazides.
