eGFR

What This Marker Means

eGFR estimates how effectively your kidneys filter waste. Higher numbers are good; lower values may indicate early or chronic kidney impairment. Age, ethnicity, and hydration influence this value.

How Alcohol Affects This Marker

Alcohol-related dehydration can temporarily lower eGFR. Chronic heavy drinking may gradually contribute to kidney strain that shows up as reduced filtration capacity.

How to Discuss With Your Doctor

Ask your doctor if your eGFR is appropriate for your age and demographic group. If low, ask whether hydration, alcohol intake, or medications could explain it—and whether retesting is needed.
