Oliguria in chronic nephritis may be due to patients' dislike of drinking water, resulting in reduced fluid intake and subsequently decreased urine output, which is usually a physiological phenomenon. However, if chronic nephritis is not actively treated and the condition gradually worsens or continuously deteriorates, leading to kidney tissue damage and severe renal failure, oliguria commonly occurs as well. Patients with chronic nephritis experiencing oliguria are advised to seek timely medical evaluation to determine the underlying cause and follow medical instructions for appropriate treatment.
