How are Homocystein and Wechseljahre related?

Homocysteine and menopause are linked through estrogen metabolism. Estrogen naturally lowers homocysteine by supporting enzymes like MTHFR and cystathionine beta-synthase. After menopause, estrogen decline can lead to rising homocysteine levels. Elevated homocysteine is an independent risk factor for cardiovascular disease, which becomes more common postmenopause. It is also associated with osteoporosis and cognitive decline. The evidence is human-moderate (epidemiological and mechanistic), but not from the provided context. A blood test for homocysteine can be informative, but home tests give only approximate values and are not diagnostic. Any elevated result should be discussed with a doctor before supplementing with folate, B12, or B6. Note: The provided knowledge context does not directly address this relationship; the answer is based on general medical knowledge.
