What is a kidney stone made of?
A
rock material
B
excess waste/ vitamins, salts, calcium
C
bone
D
None of the above
Explanation: 

Detailed explanation-1: -The most common type of kidney stone is a calcium oxalate stone. Most kidney stones are formed when oxalate, a by product of certain foods, binds to calcium as urine is being made by the kidneys. Both oxalate and calcium are increased when the body doesn’t have enough fluids and also has too much salt.

Detailed explanation-2: -Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a substance made daily by your liver or absorbed from your diet. Certain fruits and vegetables, as well as nuts and chocolate, have high oxalate content.

Detailed explanation-3: -They form from your waste. Urine contains excess salts and minerals that your body doesn’t need anymore. Sometimes, when your urine has a high amount of minerals, these waste products can build up into kidney stones. “Imagine kidney stones forming the same way rock candy is formed, ” says Dr.

Detailed explanation-4: -If your urine contains too much calcium, crystals might form in your kidneys. Over time, the crystals can combine to form kidney stones. Passing a stone can be extremely painful.

Detailed explanation-5: -There is level 1 evidence that dietary calcium intake is a protective factor against stone formation. We no longer recommend dietary calcium restriction as it may lead to increased stone formation potentially through increased oxalate absorption, and may cause bone demineralization.
