Organ Age: Do Heart, Brain, Muscle, and Metabolic Aging Occur at the Same Rate?
Short answerAging does not progress at the same rate across all organs. The cardiovascular system, brain, muscle, kidneys, liver, and metabolic system can exhibit different risk profiles. The concept of “organ age” is used to describe this heterogeneity; it is not a single universal clinical test.

How is organ age evaluated?

For the heart and blood vessels, blood pressure, lipids, ApoB/Lp(a), PWV, and imaging when necessary; for muscle, dynamometry, muscle mass, and physical performance; for the brain, cognitive evaluation, sleep, and vascular risk; for the kidneys, markers such as eGFR, cystatin-C, and albuminuria can be used.

Why is a single score not sufficient?

An individual may have a favorable cardiovascular profile while having low muscle strength or elevated metabolic risk. For this reason, a longevity plan should be based on the combined evaluation of organ and functional domains rather than a single biological age score.

Our approach at our Bodrum clinic

We use organ age not as a marketing score, but as a framework that helps identify which system needs closer monitoring. Measurements are selected based on individual risk, family history, and clinical goals.
