Bladder stones

Bladder stones are formed from the minerals and proteins found in the urine. These small crystallised masses may form anywhere within the urinary system but ultimately end up in the bladder.

Bladder stones cause severe pain, as a result of scratching the bladder wall, leading to bleeding and infection. They may also block the flow of urine. It has been found that those living in a warmer climate are more at risk of developing bladder stones. This may be a result of diet or excess sweating (affecting fluid levels).

Other people at risk are men, who are more likely to develop bladder stones over women, and also those with a hormonal imbalance and frequent urinary tract infections.

Symptoms of bladder stones include the presence of blood in the urine and severe pain.
