Coke does not dissolve kidney stones, so Coke should not be used in kidney stone treatment. Coke is a carbonated beverage and an alkaline beverage. It is not the case that taking an alkaline beverage can neutralize the acidic components in the body and dissolve the stones. Even if the stone is put into an alkaline solution, it does not necessarily dissolve. Moreover, cola is neutralized by stomach acid after it is taken orally into the body, and it is not absorbed in the gastrointestinal tract to dissolve stones. On the contrary, alkaline stone patients who drink a lot of cola for a long time may also increase the probability of stone formation. Moreover, the sugar content of cola is very high, which can lead to obesity after prolonged intake, and obesity is an important cause of stone formation, so cola cannot dissolve stones. However, during the treatment process because the patient may sometimes have a large amount of water not adapted to the situation, then drinking cola or other drinks can improve the patient’s taste, increase water intake and produce more urine to promote the discharge of stones. At the same time, the sugar in cola may increase the osmotic diuretic effect after a short time of intake, and then assisted by a large amount of water can produce a large amount of urine, which can make the stones out of the body more quickly, while cola itself does not have the effect of dissolving stones.
