It is impossible to provide a prognosis based on the information that you provide. Stage 3 chronic kidney disease (CKD) is an early stage of kidney disease. I suggest that you continue to consult with your physician on how best to delay the progression of your CKD. I suggest that you also seek to understand the cause of the CKD and that you be provided with a specific diagnosis of your CKD, if that is possible. There are some types of CKD that are associated with Hepatitis C (HEP C) and with your recent treatment for HEP C, the disease may be slowed or arrested as a result of the successful treatment.
