Which size of kidney stone is dangerous?

Dangerous? Any size that causes excruciating pain and makes you question all your life choices, I'd say! 😂 But medically, anything over 5mm often needs intervention. Don't try to pass a boulder yourself, please see a doctor.

Stones larger than 5-6mm are typically considered problematic and often require medical intervention.

Any stone that causes severe pain or blockage is dangerous. Usually, stones above 5-6mm are less likely to pass naturally. It's so important to watch your diet, especially oxalate-rich foods, but always get a doctor's opinion for diagnosis and treatment.

If a kidney stone is bigger than 5mm, it usually becomes very difficult to pass naturally and can cause serious issues. It's important to get it checked with a scan. Doctors can advise if you need medicines or a procedure. Don't wait till it's an emergency.
