These changes can alter the aging process by altering cell gene expression, and immunosenescence can increase susceptibility to osteoporosis, cardiovascular disease and some cancers. Furthermore, altering epigenetic mechanisms through environmental factors (such as nutrition, exercise and stress management) and lifestyle offers promising strategies for maintaining health during menopause and reducing the risk of chronic disease. Menopause-associated epigenetic alterations are not only linked to accelerated biological aging but also play a critical role in the pathogenesis of major chronic diseases, including cardiovascular disease, osteoporosis and hormone-related cancers.
