413 Kidney Stones [27 March 2017]

Kidney stones is a painful condition when crystals, usually calcium oxalate but also uric acid and other types, form in the kidneys. Small stones pass through without problems but larger ones can lodge in the urinary tract and block the flow of urine causing severe pain.

About 1 in 10 Canadians experience kidney stones at some time. Men are much more likely than women to develop kidney stones.

There is much you can do to prevent the formation of kidney stones:
• Drink 2-3 litres of water throughout the day to keep urine pale yellow
• Avoid soda pop as the phosphoric acid promotes stone formation
• Limit consumption of sugar, especially fructose
• Limit protein to 1g / 2 lbs lean body weight
• Limit red meat which lowers your citrate level
• Avoid or limit high oxalate content foods: beets, rhubarb, spinach, Swiss chard, sweet potatoes
• Avoid excess sodium
• Take extra magnesium, at least 1:1 with calcium
• Eat calcium-rich foods but go easy on calcium supplements – calcium in foods binds oxalates in the intestine preventing their absorption
• Maintain a healthy weight – obesity is a risk factor for kidney stones
• Exercise reduces risk of kidney stones

Stones that are too large to pass comfortably on their own require medical attention. Sound waves can be used to break up larger stones or surgery may be required. Potassium citrate is sometimes given to alkalize the urine and dissolve calcium oxalate stones but has some unpleasant side effects. Recent research using hydroxycitrate, an extract from the tamarind fruit (Garcinia cambogia) is showing promise of being a more effective and safer alternative.
