You can drink milk for kidney crystals. Currently for many types of stones, their formation is not associated with milk. This is because when you drink milk, a large amount of calcium can combine with oxalic acid in the gastrointestinal tract, which can expel the competing calcium from the body. For many patients with stones in hypercalciuria, it is definitely related to drinking high-calcium milk and a high-calcium diet. It is recommended that in all cases of kidney crystallization, you should drink plenty of water and urinate. Kidney crystallization is mainly because there is less in the urine, the concentration of crystalline material in the urine will be higher, and it will form deposits in the kidneys. Drinking more water can expel the crystals from the body, and drinking milk expels the excess urinary calcium from the body through competitive absorption.
