Introduction
If a kidney stone patient's stones are not calcium oxalate stones and their kidney function is normal, moderate consumption of rambutan will not significantly affect the condition. Rambutan is rich in vitamins, minerals, and other nutrients. Moderate intake can provide energy to the body, and its high water content can increase urine output, helping the body eliminate metabolic waste, thus offering some preventive benefits against stone formation.

Generally, patients with kidney stones can consume rambutan in moderation, but should control the intake and pay attention to their specific type of kidney stones. If in doubt, it is recommended to consult a doctor in advance. Detailed analysis is as follows:

If the kidney stones are non-calcium oxalate stones and kidney function is normal, moderate consumption of rambutan will not significantly affect the condition. Rambutan is rich in vitamins, minerals, and other nutrients; moderate intake can provide energy to the body. Additionally, its high water content can increase urine output, helping the body eliminate metabolic waste, which may aid in preventing stone formation.

If the kidney stones are calcium oxalate stones or if there is impaired kidney function, caution should be exercised when consuming rambutan. Rambutan contains a certain amount of oxalic acid; excessive consumption by patients with calcium oxalate stones may increase oxalate levels in the body and promote stone formation. For individuals with impaired kidney function, excessive consumption of rambutan might increase the kidney's workload and hinder recovery due to decreased metabolic capacity.

Before consuming rambutan, kidney stone patients should determine their specific type of kidney stones and kidney function status, control the amount consumed, avoid eating large quantities at once, and monitor their physical response after consumption. If discomfort occurs, dietary adjustments should be made promptly and medical advice sought.
