Doctors in Việt Nam are warning that habits such as insufficient water intake, high salt consumption, and a lack of physical activity can elevate the risk of kidney stone formation. Many kidney stones remain asymptomatic for extended periods, only being detected when they cause blockages. This can lead to delayed diagnosis and potential complications. Prolonged dehydration concentrates urine, fostering crystal development. Excessive salt intake increases calcium in urine, another contributing factor. Maintaining adequate hydration and an active lifestyle are crucial preventative measures against kidney stone development in Việt Nam. Early detection, even in the absence of symptoms, can improve treatment outcomes.
