Does unsweetened tea cause kidney stones?

Since I'm trying to cut sugar from my diet, I've started drinking a lot of unsweetened black tea every day. My aunt mentioned that tea can sometimes cause kidney stones. Is this true for unsweetened tea too?

Actually, I was reading about this yesterday and got so worried because I drink iced tea all day. Does anyone else here feel a dull ache in their back after drinking too much tea, or is it just my anxiety playing tricks?

Listen, don't stress yourself out too much over this. Unsweetened black or green tea does have oxalates, but having a cup or two daily won't suddenly give you stones. Just make sure you are drinking plenty of water side-by-side, okay?

Humare yahan toh sab chai peete hain bina sugar ke bhi. But yes, high amount of tea can cause stones if you don't drink normal water. Mere padosi ko doctor ne chai kam karne ko bola tha jab stone hua tha.

The science is simple: black tea is high in oxalates, which can combine with calcium to form stones. If you are highly prone to stones, swap some of that tea for water or fresh lemon juice. No need to completely stop unless your doctor advises it.

Beta, I have been having two cups of unsweetened black tea for forty years now and my kidneys are perfectly fine. The secret is just drinking 3 liters of plain water daily. Don't worry so much, life is to be enjoyed.

As someone managing high BP, I keep a close eye on everything I consume. Tea has oxalates which can lead to stones if your hydration is poor. It's always best to get your regular kidney function tests and ultrasound done during annual checkups.
