What are kidney stones and how do they form?
Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They can develop when your urine contains high levels of certain substances, such as calcium, oxalate, and uric acid, which can crystallize and stick together. Factors like dehydration, certain diets, and specific medical conditions can increase the likelihood of kidney stone formation.
When these crystals grow over time, they can form larger stones, making them more painful to pass. The size of the stones can vary, and while small stones may pass through the urinary tract unnoticed, larger stones can cause significant discomfort and complications. Recognizing the risk factors and knowing how to prevent kidney stones is crucial for maintaining kidney health.
