Living with one kidney

Hey everyone,

Two weeks ago, a routine checkup turned up a kidney tumor. Things escalated quickly, and I ended up in surgery within a week to have my entire right kidney removed. Luckily, the tumor was compact and hadn't spread yet, so the doctors are optimistic. Now, I’m just waiting for my six-week follow-up to see how my body handles being down one organ.

The catch? My doctors at the hospital didn't give me any actual guidance on what I should be eating.
I know the basics—cut back on salt, pepper, and heavy spices, especially for these first few months.

Any advice or personal experiences would be huge...

Basically, looking strictly at kidney function, if your kidneys are perfectly healthy and doing their job , you can eat pretty much whatever you want. That’s likely why you haven't been handed some strict dietary roadmap just yet.

By "whatever," I obviously mean a standard, reasonably nutritious diet, not just hitting the drive-thru at McDonald's every night and living off the processed junk that seems to be everyone's default setting these days 😉

And again, I'm emphasizing this is specifically regarding kidney health—assuming everything there is functioning properly... the tumor is really just a wake-up call that it might be time to actually start, or at least stick to, a decent way of eating.

Your other kidney is going to step up and handle everything the one you lost used to do, but you really can't afford to be reckless with it now. You have to protect it. That means avoiding physical trauma, staying on top of preventing kidney stones or infections, and keeping a very close eye on your blood sugar, urine levels, and blood pressure. As far as diet goes, there isn't some massive, complicated overhaul required. The main thing is watching your salt intake and steering clear of overly greasy or spicy foods. I'd also suggest cutting back on alcohol and caffeine. Beyond that, it’s wise to avoid overloading on protein.

Cheers! My husband had one of his kidneys taken out about 15 years ago. We basically nuked the salt in his diet—cut it down to almost nothing—so he mostly eats whatever, getting his sodium fix from things like deli meats or cheese instead.
He doesn't really have to obsess over anything specific, and you don't need to lose weight or worry about lifting heavy stuff or jarring movements like horseback riding or anything. Once your other kidney steps up and takes over the workload, you honestly forget you're even missing one. The one big rule is to stay on top of your blood pressure and keep an eye on the salt intake. Wishing you a smooth recovery. If you need anything else, just shout.

A tumor is basically... any kind of warning sign from your body, right? Like, it's telling you that something in your lifestyle isn't working out... and if you actually care about yourself, you probably need to change things up...
So, I guess you really ought to swap out some old habits... and I'm not just talking about what you eat, but how much you move, too (get outside more, seriously). Even your mindset matters—you gotta ditch whatever is stressing you out, try to enjoy each day, hang out with good friends, find what makes you happy, maybe even pick up a new hobby or something...
As for food... honestly, everyone would be better off cutting back on white sugar. Use whole grains whenever you can, stick to cold-pressed oils, and for milk, maybe try oat milk or just go with local dairy... plus, obviously, plenty of fruits and veggies. For meat, keep it light—chicken or turkey, maybe, and eat a lot of fish...
Drink enough water... don't go overboard on alcohol (I mean, one glass of decent wine won't kill anyone), and stay away from cigarettes...
Good luck!

Is there actually a chance my mom might end up losing a kidney? It’s been a while, but she had a uterine tumor years ago—thank God they cleared that out—but I can't help thinking the radiation therapy back then might have caused some lasting damage to her kidney function. She’s scheduled for surgery tomorrow where they’re going to try a procedure involving a sort of temporary shunt or bypass to see if they can jumpstart the kidney's performance. If that doesn't work, the doctors are looking at a nephrectomy. This whole ordeal started a few years back. They've been trying this "test run" approach to see if the organ will stabilize, but apparently, this is the absolute last shot. They’ll monitor her for about a week to see if there's any sign of life from the kidney, and if not, it's gone.
I really appreciate you guys. If anyone has any insight or has been through something similar, please let me know. Honestly, how much life can someone actually live with just one kidney?
Thanks in advance!

Either you pass out or the other guy backs out too.

You can absolutely live a full, long life with just one kidney—it’s totally doable to reach old age without any major issues.
My grandma has been living without one of hers for over 30 years now, and she's doing just fine.

Honestly, plenty of people out there live their entire lives with just one kidney and they do just fine...

My mother’s been getting by on just one kidney for over a decade now, and even her other one has always been a bit subpar in terms of functionality. She isn't even on any medication or anything of the sort; she just keeps up with regular checkups, monitoring her urine levels and running the occasional lab test, and everything comes back perfectly fine. Honestly, there's no reason to worry—I mean, people donate kidneys all the time when living with just one becomes impossible, so why would anyone choose to live that way otherwise?

My grandfather has been living without one kidney since he was a young man, and his other one is basically just a shriveled little thing at this point, yet he’s 73 years old and absolutely thriving... honestly, you can live a truly great and incredibly long life even with stuff like that

I mean, you can make it work. An old neighbor of mine lived to be about 75, and he managed to get through roughly 20 🙂
even with just one kidney.

My mom’s been rocking the whole single-kidney lifestyle for about 30 years now, all while managing diabetes on top of it. Honestly, she hasn't run into any major issues with just the one kidney so far.
My mom's mother—my grandma—was in the same boat and had one removed too, and she managed to live another 25 years after the surgery. She eventually passed away at 82, though it wasn't even kidney stuff that got her; it was colon cancer.

So, about two months back, I ended up with an injury that required having one kidney removed. Now I’m wondering—how long can you actually live with just one? Does the remaining kidney take on too much work or wear out faster? My doctor told me I just need to come in for checkups once a year, and since everything else looks solid and I'm only 29, I figured I'd ask if anyone here knows anything about this. Thanks in advance...

Look, if that remaining kidney is solid and working right, you can live your whole damn life with it. Seriously. For example, my brother is 46, lives with one kidney, and he's totally fine—healthy as a horse.😍 Plus, I've had a close friend who's been living the same way for 20 years now, no issues whatsoever.

So, how’s your brother eating these days? Everything normal? Does he ever just grab a beer and chill🙂\n\nAnd hey, thanks for getting back to me. Honestly, any bit of info helps more than you know...

Look, you gotta watch his diet as much as possible. I'm talking almost zero salt, cutting way back on red meat, staying far away from soda, regular checkups with the doctor, all that jazz... As for the beer? Nah, definitely not. It's just straight-up alcohol, after all.

I mean, for routine checkups, it was pretty vague. I always figured once a year was way too infrequent—I was under the impression it happened every six months or so.

Look, I don't know exactly who's handling it, but I do know he's hitting up the doctor at least two or three times a year. Plus, those blood tests for kidney function? You gotta do those multiple times a year, pretty frequently. Maybe that's why his other kidney is starting to act up now.

My grandad's heading in for kidney removal because of a tumor, so I was wondering—how long does the recovery actually take after surgery?
