Rather than “rapidly lowering” creatinine, the key is identifying why it rose. If the elevation is due to dehydration or intense exercise, 24–48 hours of proper hydration, rest, and avoiding very high meat/protein loads may help values normalize. If medications contribute (e.g., certain pain relievers/NSAIDs, some antibiotics), clinician-guided adjustments may be needed. With true kidney function decline, the fundamentals are blood pressure and diabetes control, salt management, kidney-protective therapies, and treating the underlying cause. “Herbal quick fixes” are not reliable; some may be harmful. The best plan is individualized: eGFR trends, urine albumin/creatinine ratio, imaging if needed, and a nephrology review when indicated.
