Kidney stones are hard stone-like substance that forms in the kidneys. They may not trouble you as long as they are settled in one or both the kidneys. It is only when a kidney stone moves out of the kidney and enters the ureter (the tube that carries urine) on its way to the bladder that the pain begins. The pain can be from mild to severe depending on the size and shape of the kidney stone. The stone can block the flow of urine, and may cause bleeding too.
Kidney stone formation is a common occurrence and the stones are so tiny that they pass out with the urine without any hindrance. The larger ones may cause pain and make things miserable before making their way out of the body. A large stone may get stuck in the ureter causing pressure and pain. Chances of infection rise if the stone remains stuck in the ureter for long. This may also lead to damage of the kidneys.
Types of Kidney Stones
The crystals in the urine are responsible for kidney stones. When there is an imbalance in the minerals and salts found in the urine, it may lead to their formation. Different types of stones are formed depending on the salts present in the urine.
