What Causes Kidney Stones?

Published: Apr 20, 2024

Kidney stones can be incredibly painful, but what causes them? Understanding the root causes can help in managing and preventing these hard mineral deposits.

Types of Kidney Stones

Kidney stones come in various types, with calcium stones being the most common, comprising 80% of cases. Other types include uric acid, struvite, and cystine stones. The presence of more than one type of crystal in a single stone is also possible. Each stone type has different causes and risk factors, making it important to identify the specific composition for effective management.

How Stones Form

Kidney stones form when minerals become concentrated in the urine, forming crystals that stick together. Calcium oxalate stones, for example, can form when calcium and oxalate are present in high concentrations. The process often begins in the kidney’s medullary interstitium, where crystals form and eventually erode through kidney structures. Understanding these mechanics helps in diagnosing and preventing stone formation.

Kidney stones are hard deposits formed from minerals and salts that develop in the kidneys. They can cause severe pain and may lead to complications if not treated. Understanding the causes and types of kidney stones is crucial for effective management.

Risk Factors and Triggers

Several factors can increase the risk of developing kidney stones. Dehydration is a major risk factor, as it leads to concentrated urine, which facilitates stone formation. Diets high in sodium and protein can also increase the risk, as well as certain medical conditions like obesity and digestive diseases. Identifying these risk factors can guide effective prevention strategies.
