Dmii and proteinuria. if proteinuria untreated, how long will kidneys last?

Progressive: Uncontrolled proteinuria will lead to progressive kidney failure . It's hard to give a time limit.It also depends on your sugar, cholesterol and blood pressure control.

Depend: Every person is different. I do not think i can tell you a time frame but i can tell you what to do to prevent it from happening. Close bs follow up with HGB a1c less than 6, BP less than 130/80, use ace inhibitors, good healthy diet, exercise, and follow microalbuminuria in urine closely.

Proteinuria : You need to take steps, along with your doctor, to control not only your BP but to reduce the amount of your proteinuria (p). Proteinuria can lead to other cardiovascular problems. Patients with it have more strokes, mi's and renal failure than those without it. You can take ace-i, arb's and calcium channnel blockers like Diltiazem to reduce both BP and p.
