Urinary Stones

The most common cause of urinary stones is low intake of water. The urine becomes concentrated and this allows chemicals to crystallize, thus setting the stage for urinary stone formation.

Other risk factors include:

• history of urinary stones or urinary tract infection
• family history of urinary stones
• gout
• high intake of calcium-rich foods (e.g. dairy products) or oxalate-rich foods (e.g. chocolates, peanuts)
