Drinking lemon water cannot make stones smaller. The two main types of stones commonly found in clinical practice are gallbladder stones and kidney stones. Gallstones are formed when cholesterol dissolves in bile acids and loses its balance, triggering stones. The main cause of kidney stones is the combination of oxalic acid crystals and calcium ions, leading to stone formation. Lemonade is just a vitamin-rich solution that is acidic, and only alkaline beverages are likely to shrink a few urinary stones. Lemonade does not dissolve cholesterol in a solution of bile acids or oxalic acid combined with calcium ions. Therefore, lemonade cannot dissolve gallstones or kidney stones, much less make them smaller. Patients suffering from stones should immediately go to a regular hospital to receive a comprehensive examination and follow the medical advice under the guidance of a specialized doctor.
