Did you know that kidney stones are actually not rocks but crystals made of urine? So if you think you have one, make sure you see a doctor, not a geologist!
Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They form when urine becomes concentrated, allowing minerals to crystallise and stick together. If they block the urinary tract they can be incredibly painful but usually cause no permanent damage if treated. Treatment can range from basic painkillers and water to ultrasonic waves to surgical removal in more serious cases. The risk of men developing kidney stones is higher (1 in 10) than women (1 in 35) and if you’ve had one you are more likely to get another. Ways to prevent kidney stones include drinking more fluids such as water and juices, but less soft drinks and beer, and reducing dietary salt intake.
