people with one kidney - #16229
I am really confused about a few things after learning about people with one kidney. My uncle had to have a kidney removed a while back due to cancer, and at first, I thought it was the end of the world for him! But he seems okay most days. I mean, he still plays golf, and he says he feels fine. But I keep wondering how people with one kidney manage long-term, like is there anything he needs to do differently? He doesn’t talk about it much, and when I ask, he’s like “I’m fine!” But then there’s this little voice in my head nagging me, what if he’s not? I read that people with one kidney can live just as good a life, but do they have to watch their diet or stay away from certain activities? Are there signs or symptoms he should be looking for to make sure he’s healthy? I’m a bit worried, not sure if I should push him to get more check-ups or just let him live his life. Really curious about how people with one kidney function normally, or if they have to make a ton of changes that they don’t always talk about!

Doctors’ responses
People can lead a normal and healthy life with a single kidney, but it’s important to take some precautions to ensure long-term health. A single kidney can adapt by enlarging and increasing its function to compensate for the one that’s missing. Generally, there aren’t special dietary restrictions solely because someone has one kidney, but maintaining a balanced diet and staying hydrated are crucial. It’s definitely wise to limit excessive intake of protein, sodium, and caffeine, as these can burden the kidney over time. Encouraging fiber-rich foods, fruits, and vegetables is beneficial too. Physical activity doesn’t need to be limited, and as you’ve seen with your uncle playing golf, staying active is good. However, avoiding contact sports that carry a higher risk of injury to the remaining kidney is typically advised. Regular check-ups are key—aim for at least annual visits to monitor kidney function with blood pressure checks and lab tests like serum creatinine and estimated GFR (eGFR). Watching for symptoms such as unexplained fatigue, swelling (especially in the legs or around the eyes), high blood pressure, changes in urination, or signs of kidney infection like back pain and fever is important. If he experiences any of these, he should see a healthcare provider promptly. It might be helpful to gently suggest these check-ups to your uncle, just to catch any potential issues early. It’s perfectly reasonable for you to express your concern and desire for him to maintain his health, so long as it’s done in a non-intrusive way. Overall, with appropriate precautions and regular medical follow-up, someone with one kidney can live long and fully.
