If the bladder stones are oxalate stones, to prevent their formation, one should avoid eating foods high in oxalates, such as spinach, mushrooms, potatoes, strong tea, coffee, chocolate, etc. If the stones are urate, one should reduce the intake of foods high in uric acid, such as animal offal and seafood. It is important to drink more water regularly to develop a good habit of hydration, as increased water intake can dilute the urine crystals, making it easier for stones to be expelled from the body. Thirdly, eat less high-fat food and avoid high-cholesterol foods, such as animal offal, abstain from smoking and drinking, and reduce meat consumption.
