I recently found out, at age 45, that I have osteoporosis and have begun seeing an endocronologist. All of my blood work came back normal, but my calcium level in a 24 hour urine test showed 366. He put me on Forteo and hydrochlorothiazide. 4 months later, my calcium level is still high at 353. He thinks I've stopped taking the hctz, but I haven't missed a dose. I'd like to talk to him, but he's out on med leave. He said at my initial visit that I most likely have some sort of kidney defect and I've never properly absorbed calcium. I've also had a very long history of "anemia" that was never controlled by iron. It just came and went, whether or not I was taking iron supplements. My question is, could the two be related and/or if not, what can be done to correct this problem?
