Traditional advice to people who have already had one kidney stone has been to cut back on calcium to reduce the risk of another painful episode. New research shows that this common recommendation is misplaced.
Analysis of three large groups of people who have been carefully followed up for decades demonstrates that those who consume more calcium in their diets are about 20 percent less likely to suffer a recurrent kidney stone. The three large cohorts include the Health Professionals Follow-Up Study, the Nurses Health Study and the Nurses Health Study 2, with one million participants among them.
The benefits of dietary calcium are not limited to dairy products. Calcium from sources such as kale or sardines was also protective. Calcium supplements do not appear to provide any similar benefit.

    It is very important to drink 8 ounces of water when you get up in the AM and after a bowel movement at both times your body is dehydrated.

    Just back from follow up on kidney stone event. Urologist now recommends 20 oz water with meals, 10oz upon waking, bedtime an if I get up in the night, drink 10 oz each time. I’m trying to follow this regimen.

    Hey, good advice! However, in later life, if the recommended amounts of liquids are consumed during the day, one will have to get up during the night without drinking more at the “get up times”. Still good, advice though. (Hope you have a sense of humor!) Thanks.

    I wonder if what I learned in med school fifty odd years ago is still considered valid!
    First, not all kidney stones are the same. It behooves one to learn what is the nature of the kernel of the stone.And modify the diet accordingly.
    Second, people were advised to increase their liquid consumption to dissolve the stone/s. The problem was that people drank during the day and thus dissolved the stones by day, and then, as the urine was concentrated at night, the stone/s built up at night. So the advice was modified: drink enough so that you must get up at night to urinate, and THEN drink some more!
