Kidney stones, though painful, can be prevented through dietary measures. These solid crystals form due to substances in urine like calcium and oxalate. Diet plays a crucial role in stone formation and prevention. Certain foods like spinach, beets, and nuts can increase the risk of stones, while water, citrus fruits, and bananas can help prevent them. Avoiding excess salt and animal protein is recommended. If experiencing severe pain or bloody urine, seek medical attention as tests and treatments are available for kidney stones.
