Does coffee aggravate kidney stones?

I've had recurrent kidney stones, and my doctor asked me to monitor my diet. I drink coffee every morning, so I'm wondering if it can aggravate kidney stones or make them worse.

Actually, coffee is a mild diuretic, so it can help flush things out. But because it has oxalates, drinking too much might increase the risk of calcium oxalate stones. Keep your daily water intake tracked on an app and make sure you're drinking at least 3 liters.

Haan na, coffee thoda dehydrate kar deti hai agar pani kam piyo toh. If you already have kidney stones, then too much caffeine is not good, ho na. Better to stick to simple coconut water or lemon water.

I have thyroid issues and have to get blood tests regularly. When I had a kidney stone scare, my doctor advised keeping caffeine low because dehydration can quickly make stone pain worse. Always get a scan and check with your doctor.

My doctor said one cup of coffee is fine, but drinking it like a fish will definitely irritate the kidneys, haha! If you have stones, that pain is no joke. Keep the coffee low and the water high.

Beta, kidney stone mein jyada chai aur coffee se bachna chahiye. Humare gaon mein toh log aise samay mein kulthi ki daal ka pani peete hain. Aap daktar babu se bhi ek baar zaroor pooch lo.

I had kidney stones back in the 90s, and let me tell you, dehydration is the real enemy. Coffee is okay as long as you drink double the amount of water to balance it out. Don't worry, just keep yourself well hydrated.

The urologist I consult at Medanta told me that coffee in moderation doesn't harm, but chronic dehydration from too much caffeine definitely aggravates stones. It's best to ask your doctor clearly based on your stone type.

I know how terrifying the thought of kidney stone pain is, it can make you so anxious about everything you consume. Coffee contains oxalates which can be a trigger for some. Please try to reduce it gently and talk to a urologist to ease your mind.

In moderate amounts like one cup, coffee is usually fine, but excess caffeine acts as a diuretic and can cause dehydration, which is bad for stones. Drink plenty of barley water or plain water throughout the day. It helps a lot.

When I had a kidney stone last year, my doctor told me to cut down my morning coffee to just half a cup because of the high oxalate content. I followed that and increased my plain water intake, which really helped me recover.
