Why kidney Stones Form
When everything is functioning well, substances naturally contained in urine (including magnesium, citrate, and enzymes) dissolve these minerals. but if there is not enough urine, or the concentration of the minerals is too high, stones can form. These rock-hard pieces are the result of excess mineral content. Specifically, crystals (which can turn into stones) form in the presence of high levels of calcium, oxalate and phosphorous found in urine.
