How long can a person live with one kidney?
I am really concerned and need some advice. My cousin, who is only like 30, found out she has a kidney disease and they’re saying she might have to get one kidney removed. I dunno, it’s all very sudden and scary. She’s always been so healthy and active, you know? The doctors said she could live with one kidney, but honestly I keep wondering, how long can a person live with one kidney? Are there any lifestyle changes she should make to stay healthy? Like, what if she ends up needing dialysis or something later? I mean, do people with one kidney have a shorter life expectancy? It feels like such a heavy thing to deal with. A friend brought up how athletes sometimes have one kidney and they do okay, but it’s got me thinking, how long can a person live with one kidney anyway? Will she have to be super careful all the time, or can she live a normal life? Just trying to wrap my head around all this. Any thoughts or personal experiences would be super helpful! Thanks!

Doctors' responses
A person can absolutely live a full, healthy life with just one kidney. Many people are in this situation, either from birth, due to an injury, or through kidney donation. Life expectancy is generally not reduced as long as the remaining kidney stays healthy. The body adapts well, and this single kidney can function effectively, filtering the blood as needed. That said, there are a few lifestyle adjustments and health considerations to keep in mind to ensure the kidney remains in good condition. She’ll want to maintain a healthy, balanced diet and stay well-hydrated, though it’s important not to overdo fluid intake either. Limiting salt and protein might be recommended to reduce kidney stress. Blood pressure and blood sugar levels should be monitored regularly, as they can significantly impact kidney health. Regular follow-ups with her healthcare provider will be crucial to monitor kidney function over time. Incorporating regular exercise is beneficial, but high-contact sports might carry some risk; it might be worth discussing this with her doctor. As for dialysis, it’s generally not needed unless both kidneys are compromised—having one working kidney is typically sufficient for normal body functions. In rare cases where further kidney decline occurs, a nephrologist would be the go-to person for management advice. Ultimately, living with one kidney typically still allows for a normal life without significant restrictions, focusing more on preventive care to stay as healthy as possible.
