Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Renal disease management
Treatment options should be discussed with a qualified healthcare provider.
Renin-angiotensin system blockade
ACE inhibitors or ARBs to reduce proteinuria and slow glomerular disease progression through hemodynamic and anti-inflammatory mechanisms. First-line renoprotective strategy.
SGLT2 inhibitors
Sodium-glucose cotransporter-2 inhibitors provide renoprotective benefits beyond glycemic control through improved hemodynamics and reduced inflammation in the kidney.
Additional treatment options
Kidney-protective diet
Sodium restriction, moderate protein intake, and emphasis on plant-based proteins to reduce kidney workload and minimize inflammation. Individualized based on disease stage and comorbidities.
dietaryCorticosteroid therapy
Short courses of systemic steroids for episodes of acute glomerulonephritis or rapidly progressive disease. Tapering protocols essential to minimize adverse effects.
medicationRenal function surveillance
Regular monitoring of serum creatinine, eGFR, proteinuria, and blood pressure to detect disease progression and adjust treatment regimens accordingly.
