Understanding Creatinine: How it Reflects Kidney Function

TLDRCreatinine is a measure used to understand how well your kidneys are filtering waste products. It comes from the breakdown of muscle cells and is excreted by the kidneys. However, creatinine levels can be influenced by factors like muscle mass, medications, and diet. While it is a valuable marker, it is not perfect and should be interpreted by a medical professional.

Key insights

💧Creatinine comes from the breakdown of muscle cells and is excreted by the kidneys.

💪Muscle mass can impact creatinine levels in the blood, with more muscular individuals having higher levels.

💊Certain medications can affect creatinine levels, either increasing or decreasing them.

🥩High-protein diets, especially those rich in animal protein, can transiently increase creatinine levels.

💧Dehydration and volume depletion can also cause creatinine levels to rise.
