Does green tea cause kidney stones?

I have been drinking normal tea and sometimes green tea for decades without any issues. The secret is moderation; don't drink 4-5 cups a day. Just have one cup and drink plenty of regular water throughout the day.

My grandmother used to say herbal drinks should be taken in limit. When I asked my doctor, he confirmed green tea contains oxalates which can contribute to calcium oxalate stones if you are already prone to them. I highly trust his advice.

Instead of blindly drinking green tea and then paying thousands for kidney stone treatments or scans later, it is better to plan practically. Limit the tea intake and do a basic kidney function test once a year. It costs very little and saves so much trouble.

I barely sleep five hours a day so I live on tea, and now I hear green tea might cause stones! Honestly, if I start worrying about every single drink, I will lose whatever sleep I have left. Just drink a lot of water and hope for the best.

Yes, green tea has oxalates which can sometimes lead to stones if taken in huge quantities. Just drink it in moderation.
