Kidney Stone Myth: A frequently asked issue is whether drinking more water helps pass kidney stones. In the early stages, kidney stones are often quite tiny, resembling sand grains and measuring between 2 and 3 mm. At this point, drinking more water can cause the kidneys to produce more urine, which may aid in the removal of these little stones. Even somewhat larger stones, ranging from 5 to 6 mm, have a chance of passing naturally due to increased urine flow, which can significantly expand the ureter. However, if the stone is large, medical attention may be required.
According to medical experience, the majority of patients have tiny stones that can be removed with medicine and good hydration, but others may require surgery. Maintaining appropriate hydration is crucial and individuals should aim for a daily urine output of 1.5 to 2 liters, which can be obtained from a variety of fluids including water, milk, buttermilk, and lassi. It is not required to drink large amounts of water, but maintaining adequate fluid intake can aid in the natural passing of small kidney stones.
