A kidney stone (yellow) composed of calcium oxalate, next to a tourmaline gemstone for scale. Calcium is one component of the most common type of human kidney stones, calcium oxalate. Some studies suggest that people who take calcium or vitamin D as a dietary supplement have a higher risk of developing kidney stones.
Some of the oxalate in urine is produced by the body. Calcium and oxalate in the diet play a part but are not the only factors that affect the formation of calcium oxalate stones. Dietary oxalate is an organic ion found in many vegetables, fruits, and nuts. Calcium from bone may also play a role in kidney stone formation.
A favorable outcome is more likely if a kidney transplant is complemented by a liver transplant, given the disease originates in the liver. [citation needed] Secondary hyperoxaluria is much more common than primary hyperoxaluria, and should be treated by limiting dietary oxalate and providing calcium supplementation. [citation needed]
Kidney stones are caused by high levels of the minerals calcium, oxalate, and phosphorus in urine. These minerals are normally found in urine and do not cause problems at low levels. However ...
Oxalate. The buildup of oxalate in the body causes increased renal excretion of oxalate (hyperoxaluria), which in turn results in kidney and bladder stones.Stones cause urinary obstruction (often with severe and acute pain), secondary infection of urine and eventually kidney damage. [2]
Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).
"People with advanced kidney disease or kidney stones may also need to be careful with eating large amounts of kale due to its oxalate and potassium content," cautions Newberry. "And many drugs ...
