hi, not only poor water intake , but dietary factors as well as urine infection cn make a person prone for a renal calculus.
Drinking water and other fluids is the most important thing a person can do to prevent kidney
stones. Diets high in salt, or sodium, can increase the excretion of calcium into the urine and thus increase the risk of calcium containing kidney stones. Reducing salt intake is preferred to reducing calcium intake.Foods rich in animal proteins-such as meat, eggs, and fish-contain purines and can increase the risk of uric acid stones and calcium stones. Calcium from food can help prevent kidney stone formation and help maintain bone density
. Avoiding foods rich in oxalates, such as spinach and rhubarb, may help prevent calcium oxalate stones.
