The prostate ages faster than most organs. Here is how PSA, inflammation, and lifestyle connect prostate health to biological age in men over 50.
Fasting insulin normal range by age: useful zones, not one universal cutoff
Fasting insulin ranges by age, with practical zones for HOMA-IR, lab reference intervals, repeat testing, and safer metabolic trend interpretation.
Perimenopause and biological age: which markers change before menopause
Perimenopause shifts your biological age years before your final period. Learn which biomarkers move first, how to track them, and what changes mean.
Creatinine high but eGFR normal: what does it really mean?
High creatinine with normal eGFR is often benign, but context matters. Learn common causes, cystatin C, UACR, trends, and when to ask a clinician.
