Chronic kidney disease develops after an insult to the kidney for many years. Once developed it’s not reversible. Treatment is mainly focussed to slow down the damaging process to the kidney and the overall health.
Two things basically play role in prevention of progression of chronic kidney disease:
Good control of blood pressure is very important to minimise the damage to the kidneys.
Low protein diet to decrease the load of potassium and nitrogenous waste on the kidneys (since kidneys are responsible for getting our body freed from the nitrogenous waste burdens, so the weak kidney’s workload reduces).
