It is not recommended to drink cola after kidney stones are cured, which will easily cause or aggravate the condition of kidney stones. Cola belongs to carbonated beverages, whose main components are carbonate, phosphate and a lot of sugar. Frequent drinking will increase the acidity in urine and increase the formation of calcium oxalate stones, which will easily lead to the recurrence of kidney stones and even make the condition further deteriorate. In addition, besides not recommended to drink cola after recovery, patients should avoid the intake of oxalic acid in food, such as spinach, celery, almonds, etc. Meanwhile, they should consume more fruits, vegetables, roughage, etc., and keep the habit of drinking more plain water to accelerate blood circulation and metabolism in the body, and to promote the discharging of stones. If the patient is unwell after curing kidney stones due to inadvertent consumption of cola, he should go to the hospital as soon as possible for a comprehensive examination.
