Yes, this is very serious and requires immediate medical attention. An eGFR of 6 means the kidneys are functioning at only 6% of normal capacity â this is Stage 5 Chronic
Kidney Disease (End-Stage Renal Disease). Combined with a
creatinine of 7.92 and urea of 101 (both severely elevated), waste products are accumulating in the blood at dangerous levels. At this stage, urgent nephrologist evaluation is needed and dialysis is very likely required to prevent life-threatening complications like high potassium levels, fluid overload, and uremic encephalopathy.
Next Steps
Take your grandfather to a hospital with a nephrology department IMMEDIATELY â today, not tomorrow. This is an emergency. Do not wait. The nephrologist will decide whether emergency dialysis is needed based on symptoms and full clinical assessment. Please consult me directly on Practo for a detailed evaluation.
