What problem will a person most likely have if her kidney did not work correctly?

If a person's kidneys do not work correctly, they are likely to experience a buildup of waste products and excess fluids in the body, leading to symptoms such as swelling, fatigue, and difficulty breathing. Additionally, the imbalance of electrolytes can cause complications like high blood pressure, heart issues, and bone disease. Ultimately, impaired kidney function can result in serious health risks, requiring medical intervention such as dialysis or transplantation.
