Patients with stones can drink soda, and drinking soda does not significantly increase the likelihood of having stones. Soda water is slightly alkaline, and when drunk into the body, it mainly replenishes a certain amount of water and can appropriately raise the pH of the urine, but it does not increase the probability of having stones. The causes of urinary stones are complex, and there is no single factor that causes stones to form. In addition to electrolyte abnormalities, abnormal urine pH, obstruction of the urinary tract, malformation, or chronic inflammation of the urinary tract are all causes of stone formation. Patients with hyperparathyroidism, for example, are more likely to have bilateral urinary tract stones. Patients who have not been taking calcium supplements for a long time may also be more likely to have stones due to increased urinary calcium. Urinary stones are a complex multifactorial process. Drinking soda can moderately hydrate the body and does not increase the probability of having stones, so you can drink it normally.
