Yes, moderating protein intake can help stabilize or improve eGFR in IgAN patients. A low-moderate protein diet (0.8-1.0 g/kg/day) is typically recommended. However, don't restrict protein too much - you need some to maintain health. Work with your doctor or dietitian to find the right balance for your specific situation.

A low protein diet works best when combined with other treatments your doctor has prescribed. Always discuss dietary changes with your healthcare team first.
