Hello,
Knowing your urinary protein is an important variable. If you have none, then whatever is going on will likely have an indolent course. If your kidney function stabilizes at this level and you lack proteinuria then in my opinion, there is little cause for concern. However, if your urinary protein is significantly elevated and/or kidney function declines, then I would think a nephrologist might suggest undergoing a renal biopsy to know what is causing this. In all cases, maintaining excellent blood pressure is very important and use of ACE inhibitors or angiotensin receptor blockers might have particular value especially if urinary protein is elevated.
I can only base my opinion on the information provided and your health-care provider might arrive at different conclusions once you have provided an entire history and had a physical examination performed. As always, this forum provides general medical information only and is limited to educational use only. Please discuss the above remarks with your health-care provider.
