The correct answer is B. Calcium oxalate.
Kidney stones are hard deposits that form in the kidneys. They can be made of different substances, but the
most common type is calcium oxalate. Calcium oxalate stones form when there is too much calcium and oxalate in the urine. These substances can come from the diet or be produced by the body.Other types of kidney stones include:
- Struvite stones: These stones are made of magnesium, ammonium, and phosphate. They are more common in people with urinary tract infections.
- Uric acid stones: These stones are made of uric acid, a waste product produced when the body breaks down purines. They are more common in people with gout or high blood uric acid levels.
- Cystine stones: These stones are made of cystine, an amino acid. They are rare, but they are more common in people with a genetic disorder called cystinuria.
Kidney stones can cause severe pain, nausea, and vomiting. They can also block the flow of urine, which can lead to infection and kidney damage. If you have kidney stones, it is important to see a doctor to get treatment.
