<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor.My father has kidney problem.Creatinine is at 8.He sleeps whole day.Skin has changed the color its looking black.We are thinking of starting Diaysis but can we stop Dialysis come back on medicines?Our nephrologist said if he gets more side effects then we will stop the Dialysis start medicines. Is that really possible?  <response>: Hello, creatinine levels of 8 means there is already 80 damage to the kidneys. Sometimes some patient after doing 1 or 2 dialysis can revert to better functioning of the kidneys and they wont require any further dialysis and can be managed only on medicines. But great of 8 does need dialysis to get the accumulated toxic products out of the body, so kidneys could restart their functioning. So I would suggest going with the advice of your nephrologist and undergo dialysis and then follow up regularly. Thank you
