a new hormonal landscape
once menopause has passed, the body settles into a hormonal pattern that's quite different from the cyclical rhythm of the reproductive years. rather than rising and falling across a monthly cycle, oestrogen and progesterone remain consistently low, produced only in small amounts by other tissues rather than the ovaries.
what changes, and why
during the reproductive years, the ovaries are the main source of oestrogen and progesterone, working together with follicle stimulating hormone (fsh) and luteinising hormone (lh) from the brain to drive ovulation each month. after menopause, the ovaries largely stop responding, so fsh and lh levels tend to rise and stay elevated, while oestrogen and progesterone remain low.
testosterone, which women produce in small amounts throughout life, also gradually declines with age, though this change tends to be more gradual than the drop in oestrogen.
why this matters beyond periods
oestrogen receptors exist throughout the body, not just in reproductive tissue. that means the drop in oestrogen after menopause can influence:
- bone density, as oestrogen plays a role in maintaining bone strength
- cardiovascular health, including cholesterol balance and blood vessel flexibility
- skin elasticity and hydration
- mood, sleep, and cognitive function
- vaginal and urinary tissue health
this is why menopause is often described as a whole body transition rather than something that only affects the reproductive system.
cortisol and the stress response
some women notice that stress feels harder to manage after menopause. this may be partly related to the way oestrogen and cortisol interact. oestrogen has traditionally been thought to help buffer the stress response, so its decline may leave the body more reactive to daily stressors. prioritising rest, gentle movement and habits that reduce stress can be genuinely supportive during this stage.
supporting hormonal balance nutritionally
although the ovaries are no longer driving hormone production after menopause, nutrition still plays an important supporting role. a varied diet rich in fibre, healthy fats, phytoestrogens and key micronutrients can help support overall hormonal and metabolic wellbeing during this life stage. seed cycling, which involves rotating specific seeds through the month, is traditionally associated with the reproductive years, but many of the individual nutrients in flax, pumpkin, sesame and sunflower seeds, like lignans, zinc, and vitamin e, remain relevant for postmenopausal wellbeing too.
speak with a professional
hormone levels and how they affect you are individual. if you're noticing symptoms that concern you, or want to understand your options, including whether hrt might be suitable for you, a conversation with your gp is the best place to start.
