Creatinine

What This Marker Means

Creatinine reflects kidney filtration efficiency and muscle metabolism. Stable values typically indicate healthy kidney function. Higher creatinine can suggest reduced kidney filtration, while very low levels can indicate low muscle mass.

How Alcohol Affects This Marker

Alcohol does not directly affect creatinine, but dehydration from drinking can mildly reduce kidney filtration, temporarily influencing results. Heavy long-term drinking may compound kidney stress over time.

How to Discuss With Your Doctor

Ask whether your creatinine is appropriate for your muscle mass and hydration levels. If elevated, inquire whether repeat testing or kidney follow-up is recommended.
