Urinary calculi should not eat too much oxalic acid, sodium salt and vitamin C.

1, oxalic acid: Urinary stones are mostly calcium oxalate stones. Usually try to reduce the intake of foods containing too much oxalic acid, such as spinach, cabbage, peanuts and so on. Patients with recurrent calcium oxalate stones should pay special attention to the intake of oxalic acid.

2, sodium salt: excessive intake of sodium salt will cause the discharge of oxalate, which may cause the formation of oxalate stones and aggravate the symptoms of urinary calculi.

3, vitamin C: excessive intake of vitamin C may be converted into oxalic acid in the intestine, and oxalic acid combines with calcium in the body, which is easy to produce calcium oxalate stones.

Patients with urolithiasis usually need to drink more water and urinate more, and can exercise moderately, which is helpful to expel stones from the body.
