Medical experts and health officials have provided clarifications regarding the relationship between hydration, urine acidity, and kidney stone formation. While adequate fluid intake helps dilute urine, experts note that high water consumption alone may not prevent stones caused by uric acid if urine acidity (pH levels) remains high. Highly acidic urine can cause uric acid to crystallize and form stones, even if urine appears clear.

Additionally, Indonesian Minister of Health Budi Gunadi Sadikin addressed misconceptions regarding weight management, stating that drinking ice water does not cause weight gain as it contains zero calories. He noted that weight increases are instead linked to beverages containing added sugars, such as syrups or iced coffee, which can contribute to fat storage and diabetes risk.
