How long before kidney stones pass?

A friend of mine is in a lot of pain because of a kidney stone. He's asking about the timeline for it to pass. How long do kidney stones typically take to pass on their own?

If the stone is small, like under 4mm, it can pass in about 1 to 2 weeks with a lot of fluids. I tried barley water and coconut water, which really helped me. But if the pain is unbearable or you have blood in your urine, don't wait for home remedies and see a doctor.

My 5mm stone took exactly 3 weeks to pass, and it was quite painful. The key is to drink at least 3 to 4 liters of water daily and take the smooth-muscle relaxants prescribed by your urologist. Keep a filter container to catch the stone when it passes so the doctor can analyze it.

Bro, my stone passed in like 10 days, but those 10 days were crazy. I was just chugging water like there was no tomorrow. If the pain gets too sharp or you feel like vomiting, just go straight to the clinic for a painkiller injection.

Smaller stones usually pass within 30 days. I used my water tracker app to ensure I was hitting 3.5 liters daily, which really helped speed up the process. If it doesn't pass in 4 weeks, your doctor might suggest a minor procedure to clear it.

It can take anywhere from a few days to 4 weeks depending on the stone's size. Keep drinking fluids and take your prescribed medicines on time. Hope you get relief soon.

Yes, smaller stones usually pass within 2 to 4 weeks. Drinking plenty of warm water throughout the day is the most effective way to help it along.
