Can hypocalcemia cause dizziness?

In the extreme: Hi. You should be being treated with calcitriol and calcium for your hypoparathyroidism. If you don't take your calcium & calcitriol, your calcium can get very low, and if very low, dizziness can ensue. Be safe, treat your hypocalcemia. I recommend you run your calcium at or just below the lower limit of the normal range, so you don't have too high urinary calcium and risk kidney stones. Good luck
