Dear Tiffany,
There are several types of hypercalciuria, mainly : renal leak, absorptive (Gastrointestinal absorption), resorptive(hyperparathyroid) and idiopathic(don’t know). Other disease processes may cause, hypercalciuria, but they are less common. Some of these disease processes also lead to increased calcium in the blood, these would include: hyperparathyroidism, sarcoidosis, being immobilized for a sustained period of time, taking too much vitamin D, cancer, hyperthyroidism, increased function of the adrenal gland, and the milk alkali syndrome. I think a metabolic work-up is in order which would include two 24hr urine collections and labs which it sounds like you have already had drawn. Greater than 90% of the time, the cause of the hypercalciuria can be found. I think you should talk to your doctor and in the mean time keep yourself well hydrated. A metabolic work-up should give you your answer, and a repeat 24 hr urine collection will confirm if your truly have a problem. The second 24 hr urine collection should be on a limited calcium diet.
