Lemon Juice Fights Kidney Stones

Lemon Juice Fights Kidney Stones

Q. I read a letter from someone who drank lemonade to prevent kidney stones. I’ve had kidney stones for six years. I’ve been through two lithotripsies and taken sodium bicarbonate for two years. One of the physician assistants told me a year ago to drink a shot glass of lemon juice right before bedtime. I’ve had two ultrasounds since then and no kidney stones show up. I just wish my urologist had told me this.

A. Kidney stones are extremely painful, so preventive measures are most welcome. Doctors sometimes prescribe potassium citrate to block their formation. Because lemon juice also contains citrate, doctors have considered lemonade therapy to prevent kidney stones (Journal of Urology, April 2007). This calls for one or two quarts of unsweetened or low-sugar lemonade per day.

Pure lemon juice before bedtime can be hard on tooth enamel. Be sure to rinse well!
