ARF unfolds in three stages: Stage 1 (Oliguric Phase): Here, the kidneys slow down, leading to less urine output. Toxins pile up, and you might feel bloated and fatigued. Stage 2 (Diuretic Phase): Urine output starts to pick up, but kidney function isn't back to 100%. Electrolyte issues and complications might stick around. Stage 3 (Recovery Phase): Kidney function gradually improves, and urine output returns to normal or close to it. This recovery journey can last from weeks to months
