What to watch with CLOCK and Wechseljahre?

The interplay between CLOCK gene variants and menopause is not yet well understood. CLOCK (Circadian Locomotor Output Cycles Kaput) regulates the internal clock, influencing sleep, hormone release, and metabolism. During menopause, hormonal shifts can disrupt circadian rhythms, potentially worsening symptoms like insomnia or hot flashes. Some studies suggest CLOCK polymorphisms may affect menopause timing or symptom severity, but evidence is mostly mechanistic or from GWAS, not clinically actionable. A home test for CLOCK variants cannot diagnose menopause or guide treatment. Measured biomarkers (e.g., cortisol, hormones) fluctuate daily and require clinical correlation. Do not change medications or supplements based solely on such results. Use the test as a conversation starter with a doctor, not a standalone decision tool. Be critical of marketing claims linking single genes to complex conditions.
