How small can kidney stones be?

Question

My brother had a kidney stone removed, and he said it was tiny. It made me wonder. How small can kidney stones actually be, like, can you even feel them then?

They can be as tiny as a grain of sand, maybe 1 or 2 mm. Over my years, I have seen that even these tiny ones can cause immense pain when they move. Drink plenty of water daily to flush them out before they grow.

They can be tiny like mustard seeds, ho na! But don't think small means no pain, actually sometimes they trouble you a lot while passing. Just keep drinking water and coconut water ghar pe.

Nidhi Das · Answer

They can be as small as 1mm, which usually passes naturally without surgery. Just stay hydrated and follow your doctor's advice.

I ignored a tiny 3mm stone thinking it would just wash away, but it got stuck and caused severe kidney swelling. Please get an ultrasound done if you feel any side pain, don't wait for the pain to become unbearable.

Kriti Shetty · Answer

They can be very small, even 1mm, but our bodies react differently to pain. Since metabolic health is linked, always check with a doctor to find the root cause rather than guessing. Take care of yourself.

My report says I have a 2mm stone but I am feeling a sharp pain in my lower back and tummy. Is it normal for such a small stone to cause so much pain? Did anyone else feel like crying even with tiny stones?

Rajesh Nair · Answer

I have passed a 2mm stone myself. The trick is to drink 3-4 liters of water daily and take the pain-relief and alkalizing syrups prescribed by your urologist. They slip out on their own when they are that small.
