The pain of kidney stones is said to be worse than labor– but nutrition for kidney stones can help.  Knowing about just a few possible strategies can help you ask key nutrition questions when you talk to your health care providers.

Nutrition for kidney stone resolution

Stay hydrated.  The stone precipitates when you start to get dehydrated– and it will grow. 

Ask: How much water should I be drinking each day to help the stone(s) pass?

Use your diet to alter the acidity of your urine.  Depending on the type of kidney stone, having more acidic urine or more alkaline urine can help manage kidney stones growth. Sometimes, drinking orange juice or eating certain foods can help.

Ask: Do I have acidic stones or alkaline stones?  Can I eat or drink anything to help keep them from getting bigger?

Nutrition for kidney stone prevention

Staying hydrated– all the time– helps.  This also means drinking extra with additional heat, exercise, illness, or other factors that might make you sweat or lose more water.

Ask: What are my goals for drinking beverages?  What beverages can I count toward that goal?

Maintain sufficient calcium intake.  At one point, patients were advised to limit calcium intake.  Research has since shown that sufficient calcium intake helps prevent kidney stone formation.

Ask: How much calcium per day do I need?  Can I count supplements?

Limit other compounds.  For example, extra vitamin C, high levels of oxalate, or certain medications can contribute to kidney stones.  Be sure to tell your doctor about everything you take.  

Ask: Should I stop any supplements?  What are my goals for maximum daily intake of [substance]?

Should I stop taking any of my vitamins?

Look for more research to help us figure out how to help your microbiome process oxalate, so your kidneys don’t have to.  Early research shows that a particular species of bacteria found in some people’s colon helps remove oxalate through the colon, preventing absorption from the diet into the bloodstream.
