Dietary sodium is a major determinant of urinary calcium loss (1) . High-sodium intake results in increased loss of calcium in the urine, possibly due to competition between sodium and calcium for reabsorption in the kidneys or by an effect of sodium on parathyroid hormone (PTH) secretion.
If blood calcium levels are too low, the body will break down bone and teeth to increase the blood calcium levels. If the blood levels are high, then the body uses the extra calcium to rebuild bone and teeth. The important functions of calcium in the body are too numerous to list entirely in this article. Calcium can bind to phosphate in the digestive system (preventing the phosphate from being absorbed), and it is sometimes used to help prevent or treat high phosphate levels in people with kidney disease.
