I have been diagnosed with kidney and liver disease a year ago and i just founding about it now. what is kidney and liver disease what's going to happen to my liver and kidney disease and what the treatments? is there a life expanded is??

A little more will be needed, both kidneys and liver can be acutely affected with a good chance for recovery most of the time at younger ages. Proper follow up with your primary care doc will give you the best chance of better understanding what to expect in the future.

There is not enough info in the question to give you an exact answer. What will happen will the cause/causes and the degree of damage. Hope and wish it is small and treatable
