Can taking calcium supplements cause kidney stones?

To keep my bones strong as I get older, I started taking calcium tablets. My brother had kidney stones a few years back, and he advised me to be careful. Can these supplements actually cause kidney stones?

My husband had this issue after taking cheap calcium tablets without asking a doctor. We switched to natural sources like ragi, milk, and sesame seeds, and he drinks coconut water regularly now. Natural is always gentler, but do ask your doctor before stopping any medicine.

Yes, taking high doses of calcium supplements can increase the risk of calcium oxalate stones, especially if you aren't tracking your daily water intake. I use an app to track my hydration and keep it above 3 liters. It is best to consult your doctor for the exact daily dosage you need.

Haan na, even I was thinking about this because my doc told me to start calcium. It can cause stones if we don't drink enough water throughout the day. Better to be careful and drink lots of liquid, ho na.

I agree with the advice here. Just keep your daily fluid intake high to help flush out any excess calcium from your system.

I totally get it, you want to keep your bones strong but you don't want the horrible pain of kidney stones either. It is a very valid worry! Just talk to your doctor about the safest form of calcium so you can take it without any anxiety.

Since I have PCOS, I try to be extremely cautious about any extra supplements I put into my body. It is always safer to get your doctor to run a basic kidney panel or a blood test before starting long-term calcium, just to prevent any complications.

Beta, excess of anything is bad for the stomach and kidneys. Instead of heavy tablets, try eating a bowl of fresh curd or drinking a glass of buttermilk daily. If your doctor has strictly prescribed tablets, then follow their advice but don't take them on your own.
