Question: how serious is stage 1 kidney disease?
Answer: Stage 1 CKD means you have mild kidney damage and an eGFR of 90 or greater. Most of the time, an eGFR of 90 or greater means your kidneys are healthy and working well, but you have other signs of kidney damage. Signs of kidney damage could be protein in your urine (pee) or physical damage to your kidneys.
