Can too much caffeine cause kidney stones?

My doctor warned me about kidney stones and told me to cut down on certain things. I drink coffee all day, every day, easily 5-6 cups. Could consuming so much caffeine be a risk factor for developing kidney stones?

I panicked so much when I had a mild back ache and thought my heavy coffee drinking gave me kidney stones. My doctor explained that caffeine itself doesn't cause them, but dehydration from not drinking enough water does. It is totally fine, just make sure you balance your coffee with plenty of water.

If you are worried about kidney health, please reduce coffee and start drinking barley water or coconut water. They are excellent natural ways to flush out toxins and prevent stones. But do see a doctor if you feel any sharp pain in your back or sides.

My father always says that drinking too much coffee heat-dries the body and leads to stone problems. While family wisdom is good, my doctor also confirmed that caffeine contains oxalates which can contribute to stones if you are prone to them. Do get a proper checkup.

With my 2-year-old keeping me up all night, I survive purely on black coffee. If caffeine causes kidney stones, I probably have a whole quarry inside me by now! But jokes aside, please drink lots of water because dehydration is the real culprit here.

Yes, I agree that dehydration is the main issue. Drinking excessive coffee makes you urinate more, so you must compensate by drinking at least 3 liters of plain water daily.

I totally get it, kidney stone pain is absolutely terrifying to even think about. Coffee has oxalates, so if you already have a history of stones, it's best to keep your caffeine intake very low. Take care and stay hydrated!
