Q: If an elderly person is going into kidney failure and quits taking the anti-rejection drugs, how long would he live?

A:If a person with the transplanted kidney stops taking the anti-rejection medications as prescribed, the kidney would reject, which would be obvious through a rising serum creatinine level. Later, as the patient progresses towards kidney failure, there would be other complications such as severe anaemia, bone disease, fluid gain, rising blood pressure, poor appetite and weakness, and the risk of underlying heart disease that often accompanies the worsening kidney disease.
