Yes, a human can survive with one kidney. The kidneys are essential organs responsible for filtering waste products and excess fluids from the body, regulating blood pressure, and maintaining the balance of electrolytes in the body.
Most people are born with two kidneys, but the body can function normally with just one kidney. In some cases, a person may need to have one kidney removed due to injury, disease, or donation for transplantation. After surgery, the remaining kidney may need to work harder to compensate for the loss of the other kidney, but in most cases, it can still maintain normal kidney function.
However, it's important to take care of the remaining kidney by following a healthy lifestyle, managing underlying conditions such as high blood pressure and diabetes, and avoiding behaviors that can damage the kidney, such as smoking and excessive alcohol consumption. It's also important to have regular check-ups with a healthcare provider to monitor kidney function and manage any potential complications.
